HOW DO I?
Hepatitis A is a liver infection caused by the hepatitis A virus (HAV). Hepatitis A is highly contagious. It is usually transmitted by the fecal-oral route, either through person-to-person contact or consumption of contaminated food or water. Hepatitis A is a self-limited disease that does not result in chronic infection. More than 80% of adults with hepatitis A have symptoms but the majority of children do not have symptoms or have an unrecognized infection. Antibodies produced in response to hepatitis A last for life and protect against reinfection. The best way to prevent Hepatitis A is by getting vaccinated.
March 16, 2018: There is an ongoing outbreak of hepatitis A virus in San Diego, Los Angeles, and Monterey Counties. Santa Cruz County Health Department declared an end to a hepatitis A outbreak in Santa Cruz County on February 6, 2018. There have been 12 cases of hepatitis A reported among Monterey County residents that are linked to the outbreak. Of these 12 cases, 11 were homeless people or individuals who used illicit drugs. These individuals did not have a history of travel to the other outbreak counties, suggesting transmission of the virus is occurring in Monterey County among the homeless and illicit drug use communities. If you provide services to homeless individuals, illicit drug users, and/or incarcerated individuals, please review the information under the "For Health Care Providers" section of this page.
