Hepatitis E virus (HEV) infection can lead to adverse maternal and perinatal outcomes and is a risk for mortality in pregnant women.  There are few published data on the seroepidemiology of HEV infection in pregnant women and none are available from Sudan specifically. A cross-sectional study was conducted to investigate the seroepidemiology of anti-HEV Immunoglobulin G (IgG) antibodies in mothers and newborns in Medani Hospital, Sudan. Socio-demographic, clinical and obstetric characteristics of the women were gathered using questionnaires. Anti-HEV IgG antibodies were investigated in the paired maternal and newborn sera using an enzyme-linked immunoassay (ELISA). Two hundred and nine women were enrolled to the study. The mean (SD) of their age, parity and gestational age was 27.5 (5.5) years, 2.2(1.5) and 38.8 (1.8) weeks, respectively. Out of these 209, 25 (12.5%) women had a positive result for anti-HEV IgG and two (1.0%) newborns had a positive result for anti-HEV IgG.In logistic regression none of the investigated factors (age, parity, gestational age, residency and education) were associated with anti-HEV IgG seropositivity. There is a high seroprevalence of HEV among pregnant women in central Sudan regardless of their age, parity and gestational age. Optimal preventive measures against HEV infection should be employed.
