Cytomegalovirus antibodies among healthy blood donors at Lagos University Teaching Hospital
Abstract
Objectives. Cytomegalovirus (CMV) is found worldwide in all geographical locations and socio-economic groups and is the virus most frequently transmitted to a developing child before birth. This study aimed to determine the prevalence and risk factors for CMV antibodies among healthy blood donors at Lagos University Teaching Hospital (LUTH).Methods. A cross-sectional study was carried out among consecutively recruited replacement blood donors attending the blood donor clinic at LUTH. A 5 ml blood sample was collected from each consenting participant and serum-assayed for CMV IgG/IgM using an enzyme-linked immunosorbent assay (ELISA)-based kit.
Results. A total of 122 healthy donors were recruited; 96% of the donors were IgG anti-CMV positive while 19.5% were IgM anti-CMV positive. Previous history of blood transfusion was not significantly related to CMV positivity.
Conclusion. The seroprevalence of CMV appears to be very high in this environment among healthy blood donors. Based on previous studies that showed a decrease in the incidence of CMV disease when blood is screened for CMV (IgM), the incidence of the disease can be decreased in Lagos if blood is screened for CMV.
