Hepatitis A Outbreak 
In September, LA County declared a hepatitis A outbreak affecting homeless people and illicit drug users. In addition, there has been an increase in hepatitis A cases among men who have sex with men (MSM).
  • Hepatitis A is secreted into feces and transmitted by the fecal-oral route such as ingesting food or water contaminated with the feces of an infected person, touching a contaminated surface or objects, or having sexual contact with an infected partner.
  • Hepatitis A is best prevented through good hand and environmental hygiene and by vaccination. MSM are routinely recommended to receive the hepatitis A vaccine. In the context of the current outbreak, LA County has further expanded its HAV vaccine recommendations to include 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 to these populations.
  • LAC DPH Health Update: Need for Continued Vigilance for Hepatitis A infection and Vaccination for High Risk Groups (3-15-18)   

Suspect cases of HAV in a person who is homeless 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.
