Marin Hepatitis C Dashboard

Marin County Hepatitis C Dashboard

Hepatitis C virus (HCV) is the most common cause of liver cancer and liver failure in the United States. HCV is easily diagnosed and can be cured with treatment. HCV is transmitted through blood and it is recommended that every adult is tested at least once in their lifetime. Expanding treatment can save lives and reduce community transmission. For more information about HCV, please visit the Marin County HCV Testing and Prevention page. We are using data to track the goal of the Marin Hepatitis C Coalition to eliminate HCV in Marin County.

Newly Reported Chronic Hepatitis C Infections among Marin Residents

Measuring newly reported chronic hepatitis C cases is an indicator of the burden of the virus in Marin. However, approximately 50% of people living with HCV in the U.S. are unaware they have it, because of under-screening for infection. Confirmed cases underestimate community burden, but help track progress as we promote increased screening county-wide.

Data source: California Department of Public Health Chronic Hepatitis C Registry. Includes residents of Marin at the time of diagnosis (2013-March 2022) and excludes San Quentin inmates. The chart showing data by year uses date of new diagnosis; 2022 data are incomplete. Race/ethnicity was unknown for 55% of individuals. These data will be updated annually.

Deaths Related to Hepatitis C, Cirrhosis, and Liver Cancer

Untreated HCV infection can cause premature preventable death. Deaths in which HCV, cirrhosis, and/or liver cancer is an underlying cause reflect the most serious impacts of HCV in Marin.

Data Source: California Vital Records. Marin resident deaths with hepatitis C as a primary or subsequent diagnosis are included. San Quentin inmates are excluded. 2022 data may be incomplete as causes of death are determined.

Data Source: California Vital Records. Marin resident deaths with cirrhosis or liver cancer as a primary or subsequent diagnosis are included. San Quentin inmates are excluded. 2022 data may still be incomplete as causes of death are determined.

Coalition Goal: At least 100 Marin residents will start treatment for hepatitis C in 2023

Marin Residents Treated for Hepatitis C

HCV treatment effectively cures infection, saves lives, and limits spread of the virus in our community. Successful initiation of treatment reflects success in all preceding clinical steps, including screening and evaluation for treatment. Current HCV treatment data, while not comprehensive, marks progress toward our goal of starting at least 100 people on treatment in 2023. Note because of improvements in HCV treatment in 2014, the number of newly treated infections increased in 2015 as providers began treating people living with HCV who had opted out of earlier treatments.

Data Source: Kaiser Permanente and Partnership HealthPlan. Includes Kaiser Permanente data from 2015 through 2022 and Partnership HealthPlan treatment data from 2018 through 2022. Note that these data are not yet complete as they do not include all providers. San Quentin inmates are not included.
