The seroprevalence and incidence of hepatitis E virus (HEV) infection were investigated in 416 men who have sex with men (MSM). Older age was the only factor associated with testing seropositive for HEV. Factors such as geographical origin, use of recreational drugs, number of sexual partners, and other sexually transmitted infections were not associated. Among the HEV-seronegative patients, 9 individuals seroconverted during the follow-up period.
Background: Men who have sex with men (MSM) have an increased risk of infection by pathogens transmitted by the oro-fecal route. Here, we investigated the seroprevalence and incidence of hepatitis E virus (HEV) infection in 416 MSM included in the ANRS IPERGAY PrEP trial.Results: Among the 62 (14.9% (95% CI: [11.6%-18.7%]) seropositive for HEV at inclusion, the only factor associated with testing seropositive for HEV was older age. Geographical origin, use of recreational drugs, number of sexual partners, status for HAV and bacterial sexually transmitted infection (STI) at inclusion were not associated. Among the 342 HEV-seronegative patients with available samples, 9 seroconverted after a median of follow-up of 2.1 years (IQR (interquartile range): [1.6; 3.0]).Conclusion: Overall, the HEV incidence was 1.19% per 100 person-years [95% CI: 0.54%; 2.26%]. Sexual transmission does not seem to be a major route of HEV infection in MSM, unlike HAV.
