Physicians are required to report hepatitis A cases to the Department of Public Health (Public Health)
To help stop the spread of hepatitis A, especially among vulnerable populations such as the homeless and illicit drug users, physicians are urged to report cases to Public Health.
  • In the current outbreaks, hepatitis A is primarily being transmitted person-to-person through close contact or through contact with a fecally-contaminated environment.Button for vaccination clinics
  • To prevent an outbreak in Los Angeles County, the hepatitis A vaccine is recommended for people who are homeless and/or who use illicit drugs.
  • Public Health has further expanded its hepatitis A vaccine recommendations during the outbreak. Hepatitis A vaccination is now recommended for persons who are homeless and/or who use illicit drugs and to persons who have frequent close contact with the homeless or drug-using populations. This includes those who handle or serve food or who provide personal care, janitorial, maintenance, or sanitation services for these populations.
  • Timely identification and reporting of confirmed and suspect hepatitis A cases is critical for an effective public health response and to guide outbreak prevention strategies.
  • Suspect cases of hepatitis A should be reported immediately by phone, while the patient is still at the clinical facility, in order to facilitate an on-site interview by a public health investigator and prophylaxis of contacts; phone: 888-397-3993. After hours, call: 213-974-1234.
