San Diego Hepatitis A Outbreak
On January 23, 2018, the County ended the local health emergency, declared on September 1, 2017, in response to the local hepatitis A outbreak. The action does not mean the outbreak is over, and the County will continue efforts it has taken to control the spread of the disease.
Anyone who received their first hepatitis vaccination before mid-September, 2017, should get a second dose now to complete the series and assure long-term protection. Although the first dose of the vaccine is considered to be around 95 percent effective, that protection will eventually begin to decrease and a second shot boosts immunity for between 20 and 40 years, according to the Center for Disease Control and Prevention.
The outbreak is being spread person-to-person and through contact with fecally contaminated environments. The majority of people who have contracted hepatitis A during this outbreak have been homeless and/or illicit drug users.
Efforts of the County and its community partners to halt the hepatitis A outbreak focus on three key areas: vaccination, sanitation and education
