Clin Infect Dis. 2019 Mar 19;68(7):1228-1230. doi: 10.1093/cid/ciy592.

Abstract

A high seroprevalence of hepatitis A virus (81%) among human immunodeficiency virus-negative high-risk men who have sex with men is likely why this community was largely spared from a recent hepatitis A virus outbreak in San Diego, California.

Keywords: hepatitis A; immunity; men who have sex with men; vaccination.
