Preventing a Hepatitis A Outbreak in San Francisco
San Diego, Santa Cruz, and Los Angeles counties are currently having outbreaks of hepatitis A infection, primarily among homeless persons and/or users of injection and non-injection drugs. Cases with the same strain of hepatitis A infection have begun to appear in other California counties. There have been no cases of hepatitis A this year among these same populations in San Francisco.
Health care facilities and providers should offer hepatitis A vaccine to all at-risk patients who are not known to be immune or to have completed a series with hepatitis A or hepatitis A/B vaccine. Screening for serological immunity prior to vaccination is not necessary. Vaccination consists of 2 doses of hepatitis A vaccine given at least 6 months apart. The first dose rapidly protects about 98 out of 100 persons and the second dose ensures lifetime protection. A combination hepatitis A/B vaccine is also available; at least 3 doses are required; the first dose is not as protective but this difference disappears once the full series is completed.
Persons seeking hepatitis A vaccination should visit their regular provider, or visit our SF Hepatitis A Outbreak Prevention page or dial 311 to learn the location and hours of SF clinics where they are welcome to drop in and receive free hepatitis A vaccine.

Flu Season is Here: Get a Flu Shot to Protect Yourself and Others
It’s influenza (flu) season, and flu activity is picking up in the San Francisco Bay Area. Flu season can last until May, and flu illnesses are usually highest during the winter months. Flu is a virus causing mild to severe illness, and can result in hospitalization or death. Flu is spread from person to person by coughing or sneezing or by touching your eyes, nose or mouth after touching a surface with flu virus on it.
The best way to protect yourself from the flu is to get a flu vaccine (flu shot) each year. Everyone ages 6 months or older can get the flu shot. When you get the flu shot you protect yourself as well as other people, including young children, older persons, pregnant women, and people with chronic medical conditions who are more likely to develop serious illness from the flu. The flu shot is safe, effective, and cannot cause flu illness. You can also protect yourself and others from flu by washing your hands often, covering coughs or sneezes with your sleeve or a tissue, and staying home when you are sick. See your regular health care provider to get a flu shot, or visit our resource page to find out where to get flu shots in San Francisco.
