Low prevalence of IgG antibodies against antigens of HEV genotypes 1 and 3 in women with a high‐risk pregnancy

The aim of the study was to assess whether high‐risk pregnant women have a higher prevalence of HEV during the perinatal period. This was a cross‐sectional study of 428 patients: Group 1, 127 women with a high‐risk pregnancy; Group 2, 97 asymptomatic people with reactivity to HCV or HBV; Group 3, 94 patients with clinical symptoms suggestive of HEV infection; and Group 4, 110 healthy blood donors from an urban area of Mexico City. ELISA was used to measure antibody to HEV genotypes 1 and 3. The prevalence rates of anti‐HEV IgG antibodies were 0.79% in Group 1, 2.1% in Group 2, 7.4% in Group 3, and 0% in Group 4. Women with a high‐risk pregnancy did not have a higher prevalence of HEV infection in this clinical setting.
