SF officials report jump in hep A cases among gay and bi men

An increase in hepatitis A cases has been identified among men who have sex with men in San Francisco, officials said in a health advisory Thursday.

“Seven cases have been confirmed since August 1, 2017,” the advisory says. “All seven cases lacked documentation of prior immunization. No clear chain of transmission or common exposure among these cases has been identified, nor was international travel a risk factor.”

Officials said that there’s no evidence linking the cases to hep A outbreaks among homeless people or “illicit drug-using individuals” in other parts of California and the U.S.

“However, limited genotype information suggests at least some of the cases could be linked” to other hep A outbreaks among gay and bi men in the U.S. and Europe.

Transmissions of the hep A virus occur “by consuming contaminated food or liquid and in the context of close personal contact, sexual contact, and by sharing equipment related to illicit drug use,” officials said, adding that transmission “is preventable with immunization,” and a vaccine for the virus “has been routinely recommended” for gay and by men bi the Advisory Committee on Immunization Practices for more than 20 years.
