Hepatitis A virus (HAV) has begun to spread globally among men who have sex with men (MSM). Hepatitis E virus (HEV) also may be transmitted through sexual contact among MSM. To assess the current status of these viruses among MSM in Japan, the seroprevalence of both viruses using 503 plasma samples collected between 2009 and 2018 from human immunodeficiency virus (HIV)-positive male donors who were presumed to be mainly MSM was investigated. Our results suggested that HAV may be spreading within this population, as reported elsewhere. By contrast, the spread of HEV was confirmed only among younger HIV-positive donors.
甲型肝炎病毒（HAV）已开始在男男性行为者（MSM）中在全球范围内传播。戊型肝炎病毒（HEV）也可能通过 MSM 之间的性接触传播。为了评估这两种病毒在日本 MSM 中的现状，使用 2009 年至 2018 年间从假定主要为 MSM 的 HIV 阳性男性供体采集的 503 份血浆样本，检测了这两种病毒的血清流行率。我们的结果表明，HAV 可能像其他地方报道的那样在该人群中传播。相比之下，仅在较年轻的 HIV 阳性供体中证实了 HEV 的传播。
