Medi-Cal Dental Funding Protected for Another Year in New State Budget

The 2026–27 California state budget preserves Proposition 56 funding for Medi-Cal Dental for another year, maintaining reimbursement rates that support access to dental care for millions of Californians. While this provides short-term stability for providers and patients, long-term funding remains uncertain. The California Dental Association continues to advocate for permanent protection of these critical investments in oral health.

New World Screwworm: Consider Travel History in Patients with Non-Healing Wounds

The recent detection of New World screwworm in animals in parts of the southern United States serves as a reminder to obtain a thorough travel history when evaluating patients with non-healing wounds. While there have been no locally acquired human cases in the United States and no cases in Marin County, providers should consider New World screwworm (myiasis) in patients with persistent or worsening wounds following travel to affected areas in Central America.

Patients may present with painful, draining wounds, a sensation of movement within the lesion, or visible larvae. If New World screwworm is suspected, avoid routine wound closure, collect any larvae for identification if possible, and promptly consult Marin County Public Health.

Tick-Borne Illness Reminder: Think Beyond Lyme Disease

As tick season continues, remember that anaplasmosis is one of the more commonly reported tick-borne diseases in Northern California. Patients often present with non-specific symptoms such as fever, headache, chills, muscle aches, and fatigue, which can resemble Lyme disease and other viral illnesses.

Maintain a high index of suspicion in patients with recent tick exposure or outdoor activities. Diagnostic testing should include PCR during the acute phase or paired serology when appropriate. Because early treatment improves outcomes, do not delay empiric doxycycline while awaiting test results when anaplasmosis is clinically suspected. Prompt recognition and treatment can prevent severe complications, particularly in older adults and immunocompromised patients.

Seasonal Reminder: Prepare for Heat-Related Illness

As temperatures rise this summer, consider heat-related illness in patients presenting with dizziness, weakness, syncope, dehydration, altered mental status, or exacerbations of chronic medical conditions. Older adults, infants and young children, outdoor workers, unhoused individuals, and patients with cardiovascular disease, kidney disease, or medications that impair thermoregulation are at increased risk.

Take the opportunity to counsel patients on staying hydrated, limiting strenuous activity during the hottest parts of the day, checking weather forecasts before outdoor activities, and developing a plan for extreme heat events. Encourage patients to sign up for AlertMarin to receive emergency notifications and local weather alerts.

Infant Formula Recall: Nara Organics

Healthcare providers should be aware of the recent recall of Nara Organics Whole Milk Organic Infant Formula due to a potential risk of Clostridium botulinum contamination. Although infant botulism is rare, it can cause life-threatening illness. Consider infant botulism in infants presenting with constipation, poor feeding, weak cry, decreased muscle tone, or progressive weakness. Advise families to stop using recalled products immediately and report suspected cases to Marin County Public Health without delay.

Screening Considerations for Women of Childbearing Age

Syphilis is on the rise. Test women of childbearing age for syphilis and follow CDPH syphilis screening recommendations for testing during pregnancy, including at the first prenatal visit, during the third trimester, and at delivery. Contact Marin County Public Health at 415-473-4163 for testing and treatment guidance.

Perinatal hepatitis B transmission remains preventable through routine screening, timely reporting, and newborn prophylaxis.  Providers are encouraged to screen all pregnant patients for hepatitis B surface antigen (HBsAg) during each pregnancy and report HBsAg positive patients to Public Health by completing a CMR. Communicating maternal hepatitis B and syphilis status to the delivery hospital helps ensure timely newborn follow up and prophylaxis when indicated.

Increasing Reports of Extensively Drug-Resistant (XDR) Shigella

Healthcare providers should be aware of increasing reports of antimicrobial-resistant and extensively drug-resistant (XDR) Shigella infections in California and across the United States. XDR Shigella strains have been identified among several populations, including men who have sex with men (MSM), international travelers, and persons experiencing homelessness.
 
Most Shigella infections are self-limited and do not require antibiotic treatment. However, when antibiotics are being considered, CDC recommends confirming diagnosis with stool culture and obtaining antimicrobial susceptibility testing (AST), as resistance to commonly used antibiotics is increasingly reported. The Marin County Public Health Laboratory does not currently perform susceptibility testing for Shigella isolates; AST must therefore be coordinated through a clinical laboratory.

FIFA World Cup: What You Need to Know

The 2026 FIFA World Cup will occur from June 11–July 19, 2026, with matches hosted in the Bay Area at Levi’s Stadium in Santa Clara. Significant international and domestic travel to and from the Bay Area is expected throughout the tournament period.

Large international events and mass gatherings may contribute to temporary increases in healthcare utilization and presentations for infectious diseases, sexually transmitted infections (STIs), environmentally-related illness, substance-related morbidity, and injury.

Recent local and regional activity, including mpox cases and increasing STI rates, further heightens the importance of early detection, testing, isolation, and reporting. Please review the latest Public Health Advisory with more detail.

Hantavirus

Ebola and Other Viral Hemorrhagic Fevers

Provider Considerations
Although the risk remains very low, providers should obtain a travel history for patients presenting with fever and severe illness following recent international travel. Consider viral hemorrhagic fevers, including Ebola, in patients with compatible symptoms and epidemiologic risk factors. Immediately implement appropriate infection control precautions and consult Public Health for guidance.

Vector Borne Diseases

Provider Considerations
International travelers may present with mosquito-borne illnesses such as dengue, chikungunya, Zika, or malaria. Consider these infections in patients with fever, rash, headache, myalgias, or thrombocytopenia and obtain a detailed travel history. Early diagnosis can improve patient management and support public health surveillance. Advise travelers to continue mosquito bite prevention measures after returning home, particularly if diagnosed with dengue.

STI

Provider Considerations
Large gatherings and increased travel may contribute to increased STI transmission. Consider risk-based screening for HIV, syphilis, gonorrhea, chlamydia, and mpox, and discuss prevention strategies with patients at increased risk. HIV PEP remains an important prevention tool following a potential exposure and should be started within 72 hours. Patients with ongoing risk may also benefit from discussion of HIV pre-exposure prophylaxis (PrEP). Prompt diagnosis, treatment, and reporting remain critical to reducing transmission and improving outcomes.

Ask About Electrical Needs

Summer brings warm weather and the risk for power outages. Ask patients if they have power needs for medications, nebulizers and CPAP machines and if they have battery backups. Remind patients to sign up for AlertMarin.

CalFresh Work Requirements: What Your Patients Need to Know

Starting June 1, 2026, new federal rules require able-bodied CalFresh recipients ages 18–64 without children under 14 to complete at least 20 hours per week of work, education, job training, or community service. Non-compliant recipients lose benefits after 3 months. They cannot regain them for the remainder of that 3-year window unless they come into compliance with the work requirement. Older adults > 65 years old, people with disabilities, and adults caring for children under 14 are exempt. Help patients understand these changes and connect them with Marin Health and Human Service's Employment & Training services before the deadline.

Medi-Cal Dental Changes

Marin’s health care providers can help mitigate the impact of upcoming Medi-Cal dental changes. Starting July 1, 2026, adults 19+ without satisfactory immigration status (UIS) will transition to emergency-only dental coverage, while children and pregnant or postpartum individuals remain fully covered. Encourage affected patients to complete exams and treatment now, screen for oral health needs, and refer early. Share Smile, California resources and the Find a Dentist tool to support timely access.

Measles is Back - Born Before '85? Check your Patients MMR Status

California has confirmed 43 measles cases in 2026 (0 cases in Marin at the time of publication), with one active outbreak ongoing. Nationally, more than 1,792 cases have been reported — the highest in decades. Approximately 92% of cases are among unvaccinated individuals or those with unknown status. Verify that your patients have two documented MMR doses, especially if they are at high risk for exposure. Adults born in or after 1957, especially those vaccinated before 1989, may have received only one dose. If patients recall just one childhood shot or are unsure, review and vaccinate accordingly. Call ahead before evaluating suspected cases and report immediately to Marin County Public Health (415-473-4163).

Home Renovations, Hidden Risk: A Growing Silicosis Crisis

May Mental Health Month: One Simple Step - Promote 988 in Every Visit

A recent JAMA study found an 11% decline in youth suicide deaths following the launch of the 988 Suicide & Crisis Lifeline. This is an encouraging signal for Marin, where suicide remains a leading cause of death among young people and ED visits for mental health needs are still high. Reinforce 988 awareness in your practice. During May Mental Health Month, connect patients to local events, incorporate brief mental health screening, and encourage youth and families to engage in community-based supports that reduce stigma and improve access to care.

Paralytic Shellfish Poisoning Alert

Dangerous levels of paralytic shellfish poisoning (PSP) toxins have been detected in mussels from Sonoma, Marin, and San Mateo counties. PSP toxins are not destroyed by cooking and can cause serious neurologic illness, including tingling, ataxia, and respiratory paralysis. Advise patients to avoid recreationally harvested mussels from these areas and to check current state advisories before harvesting. Consider PSP in patients with compatible symptoms and recent shellfish consumption.  Learn more at Marine Biotoxin Quarantines and Health Advisories.

Anesthesia Safety Alert: Screening for Venezuelan Ancestry

Recent guidance from the American Society of Anesthesiologists (ASA) and the Society for Pediatric Anesthesia highlights a rare but serious risk of severe neurologic injury and death associated with certain inhaled anesthetics in patients with maternal Venezuelan ancestry. This appears to be linked to a genetic susceptibility.

Providers evaluating patients—particularly children—for surgery should consider asking about maternal family history, including ancestry and any history of difficulty waking from anesthesia or prior adverse events. While rare, identifying at-risk patients may help guide safer anesthetic planning. These conversations should be approached with care and cultural sensitivity to support informed, patient-centered care.

CDPH Extends RSV Immunization Recommendation Through April 30

Due to persistent RSV activity, CDPH now recommends continuing RSV immunization with antibody products through April 30, 2026. Providers should ensure all infants aged 0–7 months receive RSV immunization within one week of birth unless the pregnant parent received RSV vaccine at 32–36 weeks’ gestation at least 14 days before delivery. Timely protection remains critical as RSV continues circulating. Please review the full CDPH guidance and implementation details here: https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/Immunization/RSV.aspx.

Screening Teens for Vaping: Marin Communities Take Action

In Marin, 17% of 11th graders report vaping (vs. 10% statewide), with increasing use of discreet nicotine pouches (e.g., ZYN, Velo, On!). On February 4, 2026, Fairfax, led by Councilmember Barbara Coler, became the first in the nation to explicitly ban the sale of nicotine and tobacco pouches. Belvedere and Tiburon have ended the sale of all tobacco products. Corte Madera, Novato, and Mill Valley are exploring additional retail policy options, including ordinances to set minimum prices and ban youth-targeted products, ordinances to end all tobacco/nicotine sales, or a combination of both. These actions strengthen prevention and underscore the importance of routine screening and early intervention in clinical care.

Strengthening Suicide Prevention for Older Adults

Suicide prevention is a critical public health priority in Marin County. Adults 65 and older represent 19% of our population but account for 31% of suicide deaths, with those older than 85 at highest risk. White men in this age group face the greatest vulnerability, often involving firearms. Risk increases following diagnoses of serious or degenerative illness, including dementia, especially within the first year. Notably, 45% of older adults who die by suicide saw a primary care provider within one month of death. The Marin County Suicide Prevention Collaborative offers trainings, data presentations, safety planning resources, support groups, and lethal means safety tools to support you and your patients. Visit the Marin County Suicide Prevention website to register for upcoming trainings, access resources, and request materials for your practice.  Resource?

From Barnyards to Beaches: H5N1 in California Seals

UC Davis has confirmed California’s first cases of highly pathogenic avian influenza (H5N1) in northern elephant seals, marking the virus’s first detection in this species in the state. Marin County benefits from the expertise of the Marine Mammal Center, whose marine wildlife health surveillance strengthens regional One Health awareness and coordination. As H5N1 continues to circulate in wildlife, including dairy cows and poultry, healthcare providers play a critical role in early recognition. When evaluating patients with influenza-like illness, please ask about recent exposure to wildlife, marine mammals, backyard flocks, commercial poultry, or dairy cattle, and follow current public health guidance for testing and reporting suspected cases.

Rising Measles Cases in California

When Seconds Count: Clinical Actions that Change Stroke Outcomes

Stroke remains a leading cause of death and disability in Marin County. Clinicians can improve outcomes by prioritizing routine blood pressure screening and aggressive management of hypertension, which is the most significant modifiable stroke risk factor. Patient education is equally critical. Ensure patients and caregivers recognize stroke warning signs using FAST (face drooping, arm weakness, speech difficulty) and understand the need to call 911 immediately. Promote community preparedness by recommending the PulsePoint app to help locate nearby AEDs and mobilize trained responders.

Every Visit Counts: Strengthening Cancer Prevention in Marin County

Cancer prevention and early detection are critical to improving health outcomes in Marin County, where cancer is the leading cause of premature death. Clinicians can help reduce cancer burden by routinely assessing risk, reviewing screening status, and following evidence-based screening guidelines. Vaccination is a key prevention strategy. Strongly recommend the HPV and Hepatitis B vaccines when indicated, using clear, evidence-based counseling to address hesitancy. National Cancer Prevention Month is an opportunity for Marin County clinicians to strengthen prevention conversations, close screening and vaccination gaps, and connect patients to timely preventive care.

Fluoride, Drinking Water, and Children's Oral Health

This month, the Marin County Board of Supervisors recognized National Children’s Dental Health Month, reaffirming the County’s commitment to prevention and evidence-based oral health. In Marin County, some patients receive fluoridated water through public systems, while others, especially those on private wells or small systems do not. Fluoride has a long, strong safety record and is effective in preventing cavities, especially children with limited access to dental care. Health care providers can support oral health by asking about water sources, reinforcing twice-daily brushing with fluoride toothpaste, encouraging regular dental visits, and connecting families to local dental resources.

Caring for Children Under 5 Exposed to Infectious Tuberculosis

Young children exposed to infectious tuberculosis face unique and urgent risks. Compared to adults, TB in children under five can progress rapidly, present with subtle or atypical findings, and lead to severe disease if not recognized early. To support clinicians navigating these challenges, the Mayo Clinic Center for Tuberculosis (MCCT) has released the Children Under 5 Exposed to Infectious TB Guide. This evidence-based resource outlines key steps for timely evaluation, diagnosis, and management.

A School Outbreak, A Clinical Reminder: Think TB

Recent TB activity in the Bay Area, including an outbreak at Archbishop Riordan High School in San Francisco, underscores the need for vigilance across the TB spectrum. Providers should maintain clinical suspicion for active TB in patients with persistent cough, fever, night sweats, or weight loss, particularly with congregate setting exposures, and promptly initiate airborne precautions and report to Marin County Public Health. Health care providers must complete this confidential online report for all suspect and active tuberculosis cases among Marin County residents. Please do not wait for laboratory confirmation before reporting.

Fourth Case of Measles in the Bay Area

Vaccine Guidance Update: California Aligns with AAP - Not CDC

This week the the California Department of Public Health (CDPH), in coordination with its partners in the West Coast Health Alliance (WCHA), endorsed the 2026 American Academy of Pediatrics (AAP) Recommended Child and Adolescent Immunization Schedule. This schedule differs from recent national changes issued by the CDC.  Providers are encouraged to refer to AAP guidance and clinical resources for the recommended vaccine schedule and counseling tools to ensure immunization practices align with California-endorsed standards and best support pediatric patients and families.

DEA Extends Telehealth Flexibilities for MAT

In partnership with HHS, the DEA issued a fourth temporary extension of COVID-19 telehealth flexibilities, ensuring medication-assisted treatment (MAT) for opioid use disorder can continue via telemedicine through December 31, 2026. DEA-registered practitioners may prescribe Schedule II–V controlled medications, including Schedule III–V OUD medications, via audio-video visits without a prior in-person exam. New final rules effective December 31, 2025 further clarify telehealth options for OUD and veterans’ care.

Staying connected matters. Strong professional community helps us share knowledge, support one another, and respond when it matters most. One way to stay engaged locally is through the San Francisco Marin Medical Society, which offers opportunities to connect with colleagues and stay informed. We also encourage providers to consider joining the Marin Medical Reserve Corps—an important way to serve the community and be ready during public health emergencies.

Contra Costa Measles Case Highlights Local Risk and Early MMR Guidance

A measles case confirmed in Contra Costa County this week was not travel related, suggesting possible local measles activity in the Bay Area. This follows a large U.S. measles resurgence (over 2,000 cases nationwide) and recent airport exposures during the holiday travel period, increasing the risk of regional spread. Measles is highly contagious, can spread before symptoms appear, and can remain airborne or on surfaces for hours. Marin County Public Health urges providers to counsel families on early MMR vaccination for children with upcoming travel. Infants 6–11 months should receive one early MMR dose before travel; children 12 months and older should follow the routine 2-dose schedule (minimum 28 days apart). Review travel plans, confirm immunity, and vaccinate at least two weeks before departure when possible. Suspect measles in patients with fever and a generalized maculopapular rash, especially when accompanied by cough, coryza, or conjunctivitis. Contact Marin County Public Health immediately to report and coordinate testing: 415-473-4163 (business hours) or 415-479-5305 (after hours).

New Vaccine Resources for Marin Parents

Winter Respiratory Season Has Arrived; Encourage Patients to Get Vaccinated

Winter respiratory viruses are increasing in Marin, raising the risk of serious illness especially for young children, older adults, and individuals with chronic conditions. Vaccination remains the most effective way to prevent severe disease and hospitalization. Clinicians should strongly recommend routine and seasonal vaccines and provide clear, evidence-based answers to patient questions. Kaiser members can find convenient, no-cost vaccine locations at https://mydoctor.kaiserpermanente.org/ncal/flu-and-covid-19-vaccine-locations/. If you don’t offer vaccines at your clinic, please direct patients to Marin County Public Health’s Vaccine Finder, which provides up-to-date information on available vaccines and sites across the county: https://coronavirus.marinhhs.org/vaccinefinder.

Clinical Guidance: Hepatitis B

Hepatitis B is a serious, vaccine-preventable liver infection that can lead to chronic disease, cirrhosis, or cancer. Routine vaccination beginning at birth and continuing through all age groups remains the most effective prevention strategy. Most people develop protective immunity, but an estimated 5–15% may not respond and need evaluation and counseling about repeat vaccination or post-exposure prophylaxis. Providers should screen for Hepatitis B, vaccinate eligible patients and address non-response appropriately.

Preventing TB Disease Starts in Primary Care

Latent tuberculosis infection (LTBI) should be managed like other chronic conditions identified in primary care. Without treatment, LTBI can progress to active TB, leading to preventable hospitalizations and complications. Treating LTBI markedly reduces reactivation risk, especially in higher-risk populations such as Asian American, Black, and Latino patients. California law now requires TB risk-based screening in adult primary care, reinforcing the role of PCPs in identifying, treating, and preventing TB disease.

Vaccine Disinformation at the Federal Level

The Centers for Disease Control and Prevention (CDC) recently revised language on its vaccine safety webpage, to suggest that the statement “vaccines do not cause autism” is not evidence-based. This wording conflicts with decades of rigorous, peer-reviewed research showing no causal relationship between vaccines and autism. Although neurologic vaccine adverse events are extremely rare and significant for the families affected, the benefits of vaccination overwhelmingly outweigh these risks. Vaccines are safe, effective, and essential for protecting children and communities. Regardless of evolving federal communications, Marin County Public Health (MCPH) remains committed to providing clear, evidence-based information and to supporting healthcare providers in promoting vaccination as a cornerstone of preventive care. We encourage providers to consult Immunize.org and the Vaccine Safety Resource Center (vaccinesafety.edu) for clear, evidence-based guidance on vaccine science and safety.

COVID-19 Vaccines for Children 6 Months to < 3 Years

CDPH Recommendation: Male Partner Treatment for Recurrent BV

The CDPH Office of STIs and HCV has issued a new Dear Colleague Letter advising clinicians to consider concurrent treatment of male partners of women with confirmed recurrent bacterial vaginosis in ongoing monogamous relationships. This approach aims to reduce recurrence and improve treatment outcomes.

Clinical Guidance: Infant Botulism Linked to ByHeart Infant Formula

Following the ongoing infant botulism outbreak associated with ByHeart infant formula, MCPH issued an advisory earlier this month. We ask healthcare providers to maintain a high index of suspicion for infant botulism in formula-fed infants. Key symptoms include constipation, poor feeding, weak cry, diminished suck/gag, and respiratory difficulty. If infant botulism is suspected, immediately consult the Infant Botulism Treatment and Prevention Program (IBTPP) for guidance.  Please report suspected cases immediately by calling 415-473-4163.

Marin Rallies in Response to Food Insecurity

Earlier this month, the County of Marin activated its Emergency Operations Center (EOC) when SNAP/CalFresh benefits were delayed. Working with community partners, the county rapidly distributed food to affected individuals and families. The Marin Community Foundation also launched the Food on Every Table Fund, which provided direct assistance to those in need and will support the development of a countywide nutrition security plan. Healthcare providers play a key role in promoting nutrition security by routinely screening for food insecurity and referring to programs including CalFresh, WIC, and community-based resources. We encourage all providers to integrate food insecurity screening and referral into everyday practice to support patients and strengthen community health.

World AIDS Day Event - December 5

Newborn Screening - Termination and New Coalition

Advances in genomic sequencing may soon allow us to screen for hundreds of conditions with a single test, and the Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC) remains disbanded following its abrupt termination by the U.S. Department of Health and Human Services (HHS) in April 2025. This decision, made without public explanation, has sparked widespread concern among medical professionals, patient advocacy groups, and policymakers due to the committee’s central role in guiding the Recommended Uniform Screening Panel (RUSP)—the list of conditions recommended for newborn screening across U.S. states. In response to the ACHDNC’s dissolution, the American College of Medical Genetics and Genomics (ACMG) announced the formation of a Newborn Screening Coalition in October 2025. While this coalition represents a crucial stopgap measure to prevent immediate harm, experts stress it cannot fully replace federal coordination. The coalition is expected to launch in early 2026 and include 15 voting members from diverse professional backgrounds.

mpox (Monkeypox)

Last week, the California Department of Public Health issued an advisory that there had been community spread of Clade I mpox in Southern California.

Respiratory Virus Season 2025-2026: Protecting Our Community

As the respiratory virus season begins, vaccination remains the most effective way to prevent severe illness from COVID-19, influenza, and RSV.  Marin County Public Health (MCPH) and leading medical organizations recommend the updated COVID-19 vaccine and the annual influenza vaccine for everyone 6 months and older. In addition, RSV vaccination is recommended for all adults 75 and older, adults aged 60 –74 with risk factors, and pregnant patients to protect their newborns. Updated vaccines are widely available this fall, including free walk-in access for Kaiser Permanente members ages 6 months and older. California’s new AB 144 secures vaccine access by establishing a statewide schedule and extending liability protection for providers through 2030. Make every patient visit a prevention opportunity by co-administering vaccines when appropriate and proactively scheduling high-risk patients.

Preserving Vaccine Choice to Protect Marin's Children

Back-to-School Resilience

As students return to school, Marin data reveal urgent concerns: local 11th graders report social-emotional distress at rates above the state average—the highest of any grade in California—and teens continue to present with elevated rates of emergency visits for self-harm, suicide attempts, and alcohol-related disorders. The Ask. Listen. Connect initiative calls on clinicians to embrace their critical role in suicide prevention by asking directly about suicidality, listening with empathy, and connecting patients to hope and help. To support providers in this work, resources such as the AAP Bright Futures Toolkit (validated screening tools), the  AAP SBIRT clinical report (substance use guidance) and additional resources on suicide risk screening provide practical evidence-based tools to strengthen early identification and intervention in youth mental health.

ACOG Affirms Safety of Acetaminophen in Pregnancy

The American College of Obstetricians and Gynecologists (ACOG) has reaffirmed that acetaminophen remains the safest first-line analgesic and antipyretic during pregnancy. A comprehensive review of decades of evidence shows no clear causal link between in-utero acetaminophen exposure and adverse neurodevelopmental or reproductive outcomes. Untreated maternal fever and pain carry well-established risks, making effective management essential. ACOG advises clinicians to recommend acetaminophen as indicated, at the lowest effective dose for the shortest duration necessary. This guidance underscores the importance of reassuring pregnant patients that acetaminophen use is safe and beneficial when clinically appropriate. Unsubstantiated claims about the safety risk of acetaminophen undermines clinical guidance and may lead to delays or avoidance of appropriate treatment, increasing potential harms for both maternal and fetal health.

Protecting Reproductive Health Access

Reproductive health care is under mounting pressure nationwide. A federal court ruling has suspended Medicaid reimbursements to Planned Parenthood for one year, and mifepristone faces ongoing legal challenges. Locally, the need is clear: between 2021 and 2023, chlamydia rates among Marin teens nearly tripled, and nearly 100 teen births were recorded. These trends highlight the importance of sustaining trusted providers and ensuring timely, evidence-based care. To support clinicians, UCSF has launched the Reproductive Health Hotline (ReproHH)—a free, nationwide, confidential resource offering real-time guidance from UCSF specialists in sexual and reproductive health. Call 1-844-ReproHH (1-844-737-7644), Monday–Friday, 8 a.m.–4 p.m. PT, or learn more at reprohh.ucsf.edu.

Ebola Advisory: What Marin Providers Need to Know

The CDC has issued a health advisory following a new Ebola outbreak in the Kasai Province of the Democratic Republic of the Congo, the second most populous (and the 2^nd largest) country in Africa. With 37 confirmed cases and 19 deaths, including health care workers, clinicians in Marin should remain alert. While the risk to the U.S. is low, providers should remain vigilant for infectious symptoms in patients who have recently traveled to the affected area. If Ebola is suspected, immediately isolate the patient, use appropriate PPE, and call Marin County Public Health immediately (415-473-4163); after hours call (415 479 5305).  Marin County Public Health’s Healthcare Preparedness Program (HPP) supports clinics, hospitals, and healthcare facilities in staying prepared for these rare but high-risk threats.

Maintaining Vaccine Confidence: The Role of Local Healthcare Providers

This month is National Immunization Awareness Month. The national spotlight has returned to vaccine safety with the relaunch of the federal Task Force on Safer Childhood Vaccines, led by NIH Director Jay Bhattacharya. It’s the first time in 25 years such a panel has been convened, and it comes at a time of wavering confidence in public institutions and in science itself. The CDC’s authority is being reduced, reflecting a broader shift in federal priorities regarding data, scientific standards, and evidence-based practices. At the same time, social media is amplifying vaccine-related misinformation, contributing to public confusion and a decline in trust in health guidance. Your impact starts here. Patients rely on you for clarity. By addressing concerns directly and connecting families to trusted resources such as Let's Get Real about Vaccines and Johns Hopkins Institute for Vaccine Safety, you build trust and strengthen vaccine confidence. Vaccination embodies the values we uphold as healthcare providers—family, community, and personal responsibility—protecting not only each patient but also our children, older parents, and immunocompromised neighbors.

Hepatitis B Birth Dose: A Critical Step in Preventing Chronic Infection

Healthcare providers play a crucial role in preventing lifelong hepatitis B virus (HBV) infection by providing timely vaccinations and educating families. HBV is 100 times more infectious than HIV, and perinatal infection carries up to a 90% risk of chronic disease, often progressing silently to cirrhosis or liver cancer. Before universal infant vaccination began in the early 1990s, over 18,000 U.S. children under age 10 were infected annually; routine immunization—beginning with a birth dose—has since reduced pediatric HBV cases by 95%.

Administering the first dose of the HBV vaccine within 24 hours of birth is essential, even if maternal screening is negative. It initiates early immunologic priming and immune memory, offering long-term protection. With its strong safety record, the hepatitis B vaccine is a trusted, life-saving intervention providers can confidently recommend.

Valley Fever: Don't Miss the Diagnosis

Although Valley fever is uncommon in Marin County, it may be under-recognized and under-tested. Consider this diagnosis in patients with respiratory or systemic symptoms lasting more than 7–10 days (e.g., cough, fever, night sweats, dyspnea, chest pain, fatigue). Take a detailed exposure history, including:

• Recent residence, work, school, or travel in endemic regions (Central/Southern California, the Southwest).
• Activities with soil or dust exposure (digging, construction, off-road recreation, agriculture).
• Outdoor occupations, especially construction, agriculture, and wildland firefighting—risk increases during fire season when soil disruption is common.

Early recognition and testing support timely management and patient education.  Learn more from the California Department of Public Health (CDPH): Valley Fever (Coccidioidomycosis).

Clinical Perspective: Understanding Mifepristone's Safety and the Importance of Informed Access

Mifepristone has been an FDA-approved component of early abortion care and miscarriage management for over two decades. Its safety and efficacy are well established, with serious adverse events remaining rare when used as directed. Major medical organizations, including ACOG and the AMA, continue to support its use based on a robust body of clinical evidence. Ideological groups seeking to restrict abortion access have promoted inflated complication rates based on unverified, non-peer-reviewed data. These claims lack clinical context and aim to undermine trust in safe, evidence-based reproductive care. As providers, it’s critical to assess such claims through the lens of evidence-based practice and uphold standards of scientific rigor. Ensuring continued access to mifepristone protects patient autonomy and reproductive health.

FDA's Juul Authorization Threatens Youth Health: What Providers Can Do

The FDA’s decision to authorize the sale of Juul e-cigarettes, including menthol flavors, is a step backward in protecting youth from nicotine addiction. Juul played a central role in the youth vaping epidemic due to its sleek design and flavored products that were especially appealing to teenagers. Despite national progress, youth use remains high, and local data indicate cause for concern. In Marin County, nearly 1 in 4 11th graders report vaping nicotine or marijuana in their lifetime. More concerningly, 14% are currently vaping nicotine and 12% are currently vaping marijuana — underscoring the urgent need for prevention and intervention. Providers should screen adolescents for nicotine and marijuana vaping, educate families about the risks of e-cigarettes, refer youth to evidence-based cessation resources, and advocate for local policies that reduce commercial tobacco and nicotine use. Learn more at https://kickitca.org.

Helping Families Navigate Healthy Social Media Use

Healthcare providers can help families address youth anxiety, depression, and social isolation linked to excessive social media use—especially doom scrolling. Instead of focusing on screen time alone, guide families to reflect on how media is used and how it makes their teens feel. Recommend screen-free routines (e.g., before bed), advise families to co-create a Family Media Plan and to have open conversations about online content. Encourage positive alternatives like outdoor activities and in-person social time. Remind parents that teens may need support their teens replacing harmful habits with healthy coping strategies. For quick guidance, review the AAP’s The 5 Cs of Media Use, which is a simple framework to help families foster intentional, balanced digital habits that support mental health and connection.

Vaccines and Informed Consent: Your Role in the Wake of ACIP Misinformation

At the June 2025 ACIP meeting, Lyn Redwood revived long-debunked claims about thimerosal and vaccine safety, misleadingly linking vaccines to autism and misrepresenting mercury science. While routine pediatric vaccines have been thimerosal-free since 2001, and extensive research confirms no connection between vaccines and autism, such misinformation continues to influence patient perceptions. Despite the lack of scientific basis, the panel voted 5-1 to recommend thimerosal-free single-dose influenza vaccines for children, pregnant women, and all adults. As a health care provider, informed consent means more than listing risks and benefits—it requires anticipating fears, dispelling myths with empathy, and grounding your guidance in clear, current evidence. Be proactive: tell patients what’s in their vaccines, what isn’t, and why vaccines remain among the safest, most effective tools in medicine. Learn more at https://www.vaccinesafety.edu/.  

Bird Flu isn't on Summer Break

Feline Flu

Marin County Public Health (MCPH) reminds doctors and veterinarians that any case of influenza A in cats must be reported immediately, as required by Title 17 CCR Section 2500. Influenza A, including H5 strains, is considered a novel virus infection with pandemic potential and poses a public health risk. Feline influenza A infection may signal a new source of human exposure. Prompt reporting allows health officials to monitor contacts and investigate sources, such as raw meat or milk. If you suspect feline flu, contact MCPH to coordinate testing (415-473-4163). For more information, visit What Veterinarians Need to Know about Bird Flu.

Firearm Injury Prevention: A Vital Role for Healthcare Providers

Each year, Marin County loses community members to firearm-related deaths—many of which are preventable. As healthcare providers, we are in a unique position to help reduce this risk and save lives.
If a patient—or someone they care about—is in emotional distress, encourage them to call or text 988, the Suicide & Crisis Lifeline. This free, confidential service is available 24/7. However, the future of this critical lifeline is at risk, as the federal government is considering cuts to its funding. Now more than ever, it’s important to raise awareness and ensure our patients know help is still available.
One of the most effective suicide prevention strategies is to increase time and distance between a person in crisis and a firearm. This means promoting safe storage practices: keeping firearms locked, unloaded, and stored separately from ammunition.
You can help by incorporating safe firearm storage counseling into clinical conversations. You should ASK (Asking Saves Kids), "is there an unlocked gun in your house?” and reinforce the importance of storing firearms unloaded and locked up. The resources below offer practical guidance:

• Marin Gun Safety Collaborative
• AAP: Gun Safety for Pediatricians
• UCSF BulletPoints Project – Provider tools for firearm injury prevention counseling

Fast Bikes, Young Riders, Big Risks: What Providers Need to Know

In response to a sharp rise in youth e-bike injuries, three more Marin jurisdictions—Larkspur, Corte Madera, and Fairfax—have joined the county in banning riders under 16 from operating class 2 e-bikes. These bikes, as manufactured, are capable of reaching 20 mph with a throttle, pose heightened safety risks, particularly for youth aged 10–15, who experience five times the accident rate of other age groups. Concerningly, it's not uncommon for e-bikes to be illegally modified to reach speeds of up to 40 mph, further increasing injury risk. The ordinance also mandates helmet use. Health care providers can support this effort by counseling families on e-bike safety, injury risks, and the importance of helmet use during routine visits.  Learn more in this article co-authored by Marin Health’s Drs. Maa and Alfrey:  Electric Bikes Are Emerging as Public Health Hazard.

Prepare Vaccine Storage for Emergencies and Power Outages

In preparation for wildfire season, all vaccine providers are recommended to register with their utility company to receive local emergency alerts.  Review and update your organization's plan for managing and relocating vaccines during emergencies, and confirm your organization has the necessary supplies, equipment, and trained staff to transport refrigerated vaccines and frozen vaccines if needed.  Identify a backup storage site that maintains proper vaccine temperatures, and if storing Vaccines for Children (VFC) Program vaccine, ensure the location complies with all VFC program requirements.  In areas prone to outages, consider installing backup power sources.  After any emergency event or power outage, document any temperature excursions, consult vaccine manufacturers if vaccines were exposed to out-of-range temperatures, and report any issues involving VFC vaccines in myCAvax.

Navigating COVID-19 Vaccine Updates: Guidance for Patients and Providers

Recent changes in federal COVID-19 vaccination recommendations have raised questions among patients and health care providers alike. It is important to understand that longstanding vaccine guidance has been developed over decades through a transparent, science-based process led by the Advisory Committee on Immunization Practices (ACIP). This committee carefully reviews data and expert input to ensure vaccine recommendations prioritize safety and effectiveness. The extensive body of scientific evidence demonstrates that COVID-19 vaccines are safe and effective for people aged 6 months and older, including pregnant individuals and young children. Vaccination remains a key tool in preventing severe illness, hospitalization, and complications associated with COVID-19, including risks during pregnancy and early infancy. Health care providers should proactively address concerns by discussing the known risks and benefits of vaccination. Encouraging patients to receive the 2024–2025 COVID-19 vaccine supports individual and public health and helps maintain broad protection against the evolving virus.

Protecting Newborns: Preventing Hepatitis B and Congenital Syphilis

What Medi-Cal Cuts Could Mean in Marin

Governor Newsom’s May Revise budget proposes significant Medi-Cal cuts that will directly impact access to care in Marin County. These include freezing enrollment for adults with unsatisfactory immigration status, adding $100/month premiums, and eliminating dental, in-home support, and long-term care benefits for certain populations. The plan also reinstates the $2,000 asset limit for seniors and limits access to one class of prescription drugs. These changes will delay care, crowd emergency rooms, and increase uncompensated costs, straining our already burdened community health centers and hospitals. Immigrants and low-income residents are essential to Marin’s agriculture, construction, hospitality, caregiving, and domestic work sectors. Limiting their access to care risks disrupting vital services and frays the connections that make Marin thrive. Learn more about #Health4All at https://health-access.org/.

Mental Health Month Reminder: Keep It Top of Mind, Every Day

As May Mental Health Month wraps up, Marin Health and Human Services (HHS) thanks all healthcare providers who joined us in raising awareness, reducing stigma, and promoting healing. Your role in supporting mental wellness—both for patients and yourselves—is essential. Despite Marin’s strong health rankings, we continue to see elevated rates of suicide, substance use, and mental health needs. Mental health must remain a priority in our everyday patient interactions, not just once a year.  Share these resources with your patients and their families:

Alert: Emerging Drug Threats — Medetomidine and Carfentanil

Two dangerous substances—medetomidine and carfentanil—are increasingly appearing in the illicit drug supply, posing serious risks for overdose and death. Medetomidine is a veterinary sedative not approved for human use. Since 2022, it has been detected in street opioids across North America. Carfentanil is an extremely potent synthetic opioid—100 times stronger than fentanyl—used to sedate large animals. It has re-emerged in parts of the illicit drug supply and may not respond to standard naloxone doses, significantly increasing the risk of fatal overdose.  Last month Santa Clara Department of Public Health confirmed the first carfentanil-related overdose death. These trends point to an increasingly toxic and unpredictable drug supply. Advise patients to avoid non-prescription pills, use fentanyl test strips, and carry naloxone (Narcan), an opioid-reversal drug. While naloxone can be effective in reversing overdoses, multiple high-dose administrations may be required in cases involving carfentanil.

TB on the Rise in Marin

Last week we Marin County Public Health (MCPH) issued an Advisory on an increase in TB cases countywide. In 2024, we treated 13 active TB cases — a 44% increase from 2023 and a 225% increase from 2022. While many cases result from reactivation of latent TB infection (LTBI) in older adults and high-risk groups, we are seeing more U.S.-born residents in local transmission patterns. MCPH and the California Department of Public Health (CDPH) are investigating a large TB outbreak. Three healthcare workers, including first responders, were diagnosed with new TB infections in the past year. California law requires primary care providers to assess adult patients for TB risk. Please review TB risk factors with your patients at their next visit.

Protecting Young Lives: Teen Driver Safety

We are deeply saddened by the recent loss of four young lives in our community. This tragedy underscores the critical reality that motor vehicle crashes remain the leading cause of death among U.S. teens. As prom and graduation season approaches—a time of both celebration and increased risk—it is vital that we work together to promote teen driver safety. Healthcare providers can play a key role by counseling families about the dangers of distracted and impaired driving, encouraging clear driving rules, and promoting safe decision-making. Impact Teen Drivers – California offers free, evidence-based resources for parents, teens, and educators to help prevent accidents.

Protecting Patient Care Amid Rising Deportations

The new administration’s immigration policies focus on ramping up border restrictions and interior enforcement, including rescinding protections at sensitive locations including health care facilities. These actions heighten fear among immigrant families, including U.S.-born children, impacting health, well-being, and access to care.  Detentions and deportations create fear and trauma in families, leading to mental health struggles and causing many to avoid seeking needed health care. Health care providers can support immigrant families by creating safe, welcoming environments, reinforcing patient confidentiality, developing protocols for potential encounters with immigration enforcement, and ensuring access to essential care.

Message from the Health Officer

When I heard about the Woodacre accident, my heart — like the hearts of so many in Marin — broke. My children are 12 and 14 years old; it easily could have been them. As our family prayed for the grieving families and friends, we also took time to talk about the importance of safe driving. In our daily gratitude practice, we reflected on how much we take for granted in this fragile, precious, and fleeting life. Even as we continued with the routines of daily life, the weight of the community’s grief stayed with us — a reminder of how deeply we are all connected in times of sorrow. Let’s look out for each other and drive with extra care — every choice we make can mean everything to someone else.

Measles Exposure Among International Travelers

Marin County Public Health recently investigated two cases involving travelers exposed to measles during a long-haul international flight. A key challenge in our response was the inability to access vaccination records quickly. Exposed individuals may be subject to quarantine, school or work exclusion, and public health monitoring without documented proof of immunity.
This serves as an important reminder:

• Encourage patients to review and carry copies of their vaccine records.
• Ensure travelers are up to date on MMR vaccination, particularly for international travel.
• Discuss the risks of exposure without immunity, including potential quarantine and post-exposure protocols.

Please support your patients in preparing for safe travel and help us strengthen community protection against measles and other vaccine-preventable diseases.

Time to Prepare for a Spring COVID Wave

Ask. Screen. Connect.: Supporting Mental Health

Bird Flu Update

As flocks of wild birds return to the north, we are preparing for another surge in bird flu activity statewide.  Migratory birds play a key role in the global spread of avian flu by shedding the virus along seasonal flyways and infecting poultry flocks and dairy herds. We are also seeing more cases among cats from direct contact with infected birds or consumption of raw meat or milk from infected animals. Healthcare providers should consider avian flu in patients with conjunctivitis or respiratory symptoms and animal exposure. Suspected cases must be reported immediately to Marin County Public Health by calling 415-473-4163. Collect respiratory and eye swabs for testing; initiate antiviral treatment and offer prophylaxis to close contacts. Providers should stay updated with guidance to ensure early detection and response. Marin County Public Health provides local updates on our Bird Flu (H5N1) webpage.

Message from the Health Officer: Public Health is Essential

I still wear a t-shirt from the pandemic that says, “Apparently, I’m essential. #PublicHealth.” It was a quiet badge of honor from a time when thousands of Marin residents stood up to protect our community. History tells us public health is easy to forget—until the next crisis hits. Marin County Public Health along with health departments nationwide are now grappling with the CDC’s abrupt and short-sighted withdrawal of $11.4 billion in COVID-era funding. This critical investment in a chronically underfunded public health system enhanced disease surveillance, prevented outbreaks in nursing homes, and supported rapid responses to rising threats like avian flu, measles, and resurgent tuberculosis. Public health is our first line of defense. Vaccination, education, and infection control don’t just prevent illness—they save lives and reduce hospitalizations, long-term complications, and health care costs. For example, a single measles vaccine costs under $30; one outbreak can cost hundreds of thousands.
Now is the time to champion sustained public health funding. An ounce of prevention is worth many times more than a pound of cure.

Thank you for your continued support of public health and partnership.

Fentanyl Deaths in Sonoma County

Last weekend, two teens died in Santa Rosa due to suspected fentanyl poisoning; two other teens were hospitalized. It was reported that the youth believed they were using cocaine; however, their drug supply contained fentanyl.  Overdose is the leading cause of death in Marin County for residents aged 55 and younger. Fentanyl, a high potency synthetic opioid, is the most common substance involved in local overdose deaths.  Visit Data Dashboard — OD Free Marin to learn more about overdose in Marin County.  See the Public Health Update published this week.
 Providers are asked to share the following messages with people who use drugs:

• Carry Naloxone. You may need to use multiple doses. Get free Naloxone: odfreemarin.org/nalaxone/
• Test your drugs before using. Fentanyl test strips are available through Ritter Center.
• Start low and go slow.
• Do not use drugs alone. If no one will be close by while you are using, call Never Use Alone at 1-800-484-3731

Flu Update

Bird Flu Update

The H5N1 bird flu continues to spread, affecting wild birds, poultry, and dairy cows. While the risk to the general public remains low, there have been over 70 confirmed human infections, mostly from direct contact with sick animals. The virus hasn't yet mutated to spread between humans. The U.S. has ramped up its response, including financial aid for poultry producers and research into vaccines. Primary care providers should advise at-risk individuals, such as farmers and families with backyard poultry, on precautions to prevent infection:  avoid direct contact with birds and other animals that could be infected with bird flu; get the seasonal flu vaccine; only consume pasteurized dairy products; and cook poultry and eggs to an internal temperature of 165°F.  Marin County Public Health will provide local updates on our Bird Flu (H5N1) webpage.

Eating Disorders

In recognition of Eating Disorder Awareness Week, Kelly Harvard, Senior Program Coordinator in our Maternal, Child, and Adolescent Health program, published an Op-Ed in the Marin IJ discussing the critical role of negative body images in adolescent eating disorders.. As healthcare providers, it is essential to understand the profound impact body dissatisfaction has on both mental and physical health, particularly among adolescents and marginalized populations, such as LGBTQ+ youth. Negative body image is a significant contributing factor to eating disorders, depression, anxiety, and self-harm, with the onset typically occurring between the ages of 12 and 25. Providers are in a unique position to offer early recognition, intervention, and ongoing support for individuals affected by body image issues.

Possible Medi-Cal Cuts Ahead

Message from the Deputy Health Officer

In an ever-changing world, the partnership between communities and healthcare providers is crucial. Communities are the bedrock of public health, offering the social, cultural, and environmental context for our lives. Effective public health strategies are rooted in community engagement, including health education, disease prevention, and promoting healthy lifestyles.
 
Healthcare providers extend beyond their role in clinical care by collaborating with community organizations, contributing to public health research, and sharing data. These partnerships lead to improved health outcomes, reduced healthcare costs, and increased health equity. By working together, communities and healthcare providers can eliminate disparities and ensure that everyone has access to quality care. Together, we can build a healthier and more just future for all.

Updated Return to Work Guidelines for Healthcare Personnel with Contagious Illness

This month, the California Department of Public Health (CDPH) issued updated guidance on work exclusions for healthcare personnel (HCP) with contagious illness.  This guidance applies to HCPs with COVID-19, influenza, and other acute respiratory viral infections, regardless of diagnostic testing results.  Healthcare personnel are not to return to work until at least 3 days have passed since symptom onset and at least 24 hours have passed with no fever (without using fever-reducing medicines), symptoms are improving, and they feel well enough to return. Returning healthcare personnel should wear masks when they return to work.

Winter Respiratory Virus Season

Bird Flu Update

H5 bird flu is still widespread in wild birds and continues to infect California poultry and dairy cows. There are now 67 confirmed human cases nationwide, primarily among dairy and poultry workers, and one death. It is suspected that H5N1 may be underdiagnosed, especially in California, where 536 dairy herds are experiencing outbreaks and remain under quarantine.  Centers for Disease Control and Prevention (CDC) has advised hospitals, laboratories, and clinicians to test and subtype for non-seasonal flu to enhance disease surveillance. While the H5N1 avian influenza remains a low risk to the public, enhanced surveillance is needed to monitor for potential human-to-human transmission. If you see symptoms consistent with bird flu, including fever and conjunctivitis, after contact with animals (e.g., backyard flocks) or consumption of raw milk products, contact Marin County Public Health to coordinate testing (415-473-4163).

Southern California Wildfire Update

Message from the Health Officer

This week, the rise in Immigration and Customs Enforcement (ICE) removal operations hits close to home for me. As a descendant of both documented and undocumented immigrants—who worked both “legally and illegally” to support their families—and the wife of a refugee, I deeply understand the sacrifices that allow my family the privilege to live, work, and attend school in Marin. Most immigrants in our country have faced unimaginable challenges to create a better life for their loved ones.  They and their children, who are citizens, make valuable contributions to our communities. Our local economy depends on an undocumented workforce in essential industries like agriculture, caregiving, construction, and hospitality. While we await a fair immigration system that balances security, offers a pathway to citizenship, and meets the needs of immigrants and the labor market, I hope our community will support a compassionate approach that ensures undocumented residents have access to essential services, legal aid, and economic opportunities. I am thankful for partners like Canal Alliance for helping immigrants and their families “achieve their dreams.”

Stay strong and kind,

Bird Flu

Last week Marin County issued a public health advisory in response to increasing H5N1 activity statewide, and after investigating what was considered by CDPH a suspect case in a toddler who became ill after raw milk consumption.  Additionally, the Governor proclaimed an emergency to coordinate a multi-agency response to H5N1.  CDC has confirmed the first severe case of bird flu in a person in Louisiana, who was hospitalized with severe symptoms after interacting with an infected backyard bird flock. CDC maintains that there is no evidence of human-to-human transmission, and that the virus is not considered endemic to the U.S. in either animals or humans. While the risk to the public remains low, clinicians should inquire about potential occupational and/or raw milk exposures particularly for patients presenting with red eyes as part of their clinical complaint.  Public health’s H5N1 webpage is up to date.

Advisory: Masking and Vaccination in Health Care and Long-term Care Facilities

As respiratory viruses surge this winter, Marin County Public Health issued an advisory strongly recommending that healthcare and long-term care facilities implement masking policies from November 1, 2024, to March 31, 2025. All staff and visitors should wear high-quality masks during close contact with patients and residents. Facilities are urged to review Cal/OSHA standards, promote vaccinations, enforce hand hygiene, enhance cleaning protocols, and monitor respiratory virus activity. These measures aim to reduce transmission risks and protect vulnerable populations during the winter season.

National Respiratory Syncytial Virus (RSV) Month

October is National Respiratory Syncytial Virus (RSV) Month. RSV is the leading cause of hospitalization for infants in the United States. Pregnant people can help protect their babies before birth by getting the RSV vaccine at 32 through 36 weeks of pregnancy, from September 1 – January 31.  Pregnant people also need updated 2024-25 COVID-19 and flu vaccines as well as the Tdap vaccine at 27-36 weeks gestation.  Centers for Disease Control and Prevention (CDC) has updated its Guidelines for Vaccinating Pregnant Persons.

Updated Syphilis Screening Recommendations

• Once in a lifetime screening of all sexually active persons 15-44 years old.
• Annual screening whenever a person is tested for HIV or other sexually transmitted infections, including mpox.
• All pregnant persons at confirmation of pregnancy or first prenatal encounter, early in the third trimester and at delivery.
• All persons 15-44 years old who enter a correctional facility at the time of intake.

Marburg Virus Disease in Rwanda

Rwanda is experiencing its first outbreak of Marburg virus disease (MVD), with 65 reported cases and 15 deaths as of October 28, 2024. Most infections are among healthcare workers. The CDC is assisting the Rwandan Ministry of Health, deploying scientists to support case tracking, laboratory testing, and infection control. Currently, there are no Marburg cases in the U.S., and the risk remains low. Most ill travelers returning from an area with an active MVD outbreak are usually ill with a more common infection, such as malaria. Healthcare providers are urged to stay informed about the outbreak. Marin County Public Health is working with local hospitals to ensure their readiness to receive and isolate a person of interest and care for the patient.  Health care providers should contact Marin County Public Health immediately if a confirmed traveler from a filovirus affected area or a close contact presents with viral symptoms.  Call (415) 473-4163 during business hours; after hours call (415) 479-5305.
