Hepatitis A Outbreak in Los Angeles County
On September 19, 2017, The Los Angeles County Department of Public Health (DPH) declared a local outbreak of hepatitis A in Los Angeles County (LAC) because of recently identified locally-acquired cases (press release, 9/19/17). Cases have occurred in persons who are homeless and/or use illicit drugs (injection and non-injection), with several cases also occurring among people who provide services to the homeless.

In addition, LAC DPH announced an increase in cases of hepatitis A among men who have sex with men (MSM) on November 2, 2017. The increase in cases is consistent with other worldwide outbreaks nationally and internationally.  HEALTH ALERT
