Seroepidemiological Survey of Cytomegalovirus Infection among Pregnant Women in Sudan.

Human Cytomegalovirus (HCMV) is a leading healthcare problem associated with stillbirth and congenital abnormalities. Determining the seroprevalence and the possible risk factors related to HCMV infections may be a cornerstone in preventing its complications. This cross-sectional study was conducted in Kassala and River Nile States to determine the seroprevalence and risk factors associated with HCMV infection in pregnant women. One hundred eighty-four (n = 184) blood specimens were collected from pregnant women from February 2018 to January 2020. Enzyme-linked immunosorbent assay (ELISA) was used to detect HCMV-specific IgG and IgM antibodies. Socio-demographical characteristics of the women were collected using structured questionnaires. The results showed that HCMV IgG was detected in 170 (92.4%) of the blood specimens, and IgM was detected in 29/93 (31.2%). There was a significant relationship between the history of miscarriage and the presence of IgG and IgM with a p-value = 0.001 and between HCMV IgM and gestational stage (p-value = 0.028). The study found a strikingly high seroprevalence of HCMV infections among pregnant women in the investigated States. This high percentage of illiterate housewives living in rural areas makes it possible to reduce the incidence of HCMV infection in pregnant women by improving their knowledge, attitude, and practice regarding the route of viral transmission, which may reflect in lowering the rate of congenital diseases in their infants.
