Marin County Public Health urges the public to take precautions if traveling to Zika Virus (ZIKV) transmission areas.
Pregnant women should avoid travel to areas with active ZIKV outbreaks, including Puerto Rico, and the U.S. Virgin Islands. Pregnant women should also consider postponing non-essential travel to South Florida.
If you must travel to or live in one of these areas, talk to your healthcare provider first and strictly follow steps to prevent mosquito bites.
If you or your partner live in or travel to an area with Zika, use condoms the right way, every time you have sex or do not have sex throughout the pregnancy. Sex includes vaginal, anal, and oral sex.
Women trying to get pregnant
Before you or your partner travel, talk to your healthcare provider about your plans to become pregnant and the risk of Zika virus infection.
You and your partner should strictly follow steps to prevent mosquito bites.
Prevent exposure to mosquito bites by practicing the "Three Ds": use DEET or other EPA-registered insect repellent; wear proper clothing and repellent if outside from Dusk to Dawn; and Drain all sources of standing water.
The invasive mosquito responsible for ZIKV transmission has not been found in Marin County. To date, there have been no locally-acquired, mosquito-borne cases of ZIKV disease in Marin County, the Bay Area, or California.
What is the Zika virus?
Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito
How does Zika virus spread?
Zika is spread to people primarily through the bite of an infected Aedes species mosquito (Aedes aegypti and Aedes albopictus). A pregnant woman can pass Zika virus to her fetus during pregnancy or around the time of birth. Also, a man infected with Zika virus can pass it to sex partners.
What are the symptoms of Zika?
The most common symptoms of Zika virus disease are fever, rash, joint pain, and red eyes. Other symptoms include muscle pain and headache. Many people infected with Zika won't have symptoms or will have mild symptoms, which can last for several days to a week.
How is Zika diagnosed?
To diagnose Zika, your doctor will ask you about recent travel and symptoms you may have, and collect blood or urine to test for Zika or similar viruses. View California Department of Public Health's Zika Patient Self Assessment Form.
How is Zika treated?
Zika virus disease is usually mild and requires no specific treatment. People sick with Zika virus should get plenty of rest, drink enough fluids, and treat pain and fever with acetaminophen. If symptoms worsen, they should seek medical care and advice.
How can Zika be prevented?
The best way to prevent Zika is to protect yourself and your family from mosquito bites:
- Avoid TRAVEL to areas that are known to have active Zika transmission: World Map of Areas with Risk of Zika
- Use Environmental Protection Agency (EPA)-registered insect repellents
- Wear long-sleeved shirts and long pants
- Sleep under a mosquito bed net if air conditioned or screened rooms are not available or if sleeping outdoors
Zika can be spread by men to their sex partners. People whose male sex partners have traveled to or live in an area with Zika can prevent Zika by using condoms correctly every time they have sex or by not having sex.
What is the risk of Zika in pregnancy?
Microcephaly and other problems (eye defects, hearing loss, and impaired growth) have been detected among fetuses and infants infected with Zika virus before birth.
Is there a Zika vaccine?
Currently, no vaccine or medication exists to prevent or to treat Zika virus infection.
