Prospective study of Hepatitis E Virus infection among pregnant women in France.

Abstract : BACKGROUND: Hepatitis E Virus (HEV) infection has a poor prognosis among pregnant women from high endemic countries. HEV-prevalence and incidence among pregnant women is unknown in high-income countries such as France. This prospective study was conducted to assess HEV infection in this setting. FINDINGS: An overall HEV prevalence of 7.74% was observed among 315 pregnant women. Seroprevalence was higher in south than in north of France (29.3% vs. 3.6%, p < 0.0001), and women with detectable IgG were older. No IgG seroconversion or IgM detection were observed during pregnancy. CONCLUSIONS: Data suggest that HEV infection is a rare occurrence during pregnancy even in regions of western countries with high seroprevalence rates.
