Sero-prevalence and risk factors for cytomegalovirus infection among pregnant women in a teaching hospital in Ogun state, Nigeria

Background: Infection with cytomegalo virus is usually asymptomatic however in pregnant women the risk of congenital infection and foetal  abnormalities makes antenatal screening for CMV infection necessary. The aim of this study was to determine the sero-prevalence and risk factors for  CMV infection among pregnant women in Babcock University Teaching Hospital (BUTH), Ilishan Remo, Ogun State, Nigeria.Methods: The study was a cross-sectional descriptive study conducted between January and May, 2017 on patients attending the antenatal clinic of  Babcock University Teaching Hospital. Enzyme Linked Immunosorbent Assay (ELISA) Kits were used to determine IgM and IgG anti CMV antibody titresinvenous blood samples obtained from study participants.Results: A total of 80 patients were recruited into the study. The mean age was 30 years.All (100%) respondents were sero-positive for anti CMV IgG  antibodies while 28.75% of respondents were seropositive for anti CMV IgM antibodies.Conclusion: There was a highsero-prevalence rate of CMV infection in the study. Screening of pregnant women for CMV infection is necessary due to the  risk of congenital infection and fetal defects.
