  •   Monterey County Declares Hepatitis A Outbreak Among Homeless Population

    Since early 2017, the San Diego and Santa Cruz County Health Departments have been investigating local hepatitis A outbreaks among individuals who are homeless or use illicit drugs. Unfortunately, disease levels in Monterey County have now reached outbreak levels. Since October 2017, hepatitis A has been diagnosed in 9 individuals with a history of homeless in Monterey County. These individuals did not travel outside of Monterey County so are assumed to have become ill due to transmission within the homeless and illegal drug use communities in Monterey County.
