Abstract
The prevalence of infections which have deleterious effects to either the mother or the fetus during pregnancy are unknown in Cameroon. To formulate appropriate antenatal screening policies for the Central Mother and Child Clinic in Yaounde, we tested random sera obtained from 1,014 stored samples previously obtained from pregnant women. One hundred and fifty sera were tested for the presence of the hepatitis B surface antigen (HBsAg), 544 for syphilis antibodies, 192 for antibodies to rubella and 192 for antibodies to Toxoplasma gondii. We found the HBsAg in 25.3% (38/150) of the subjects, antibodies against syphilis in 15.9% (87/544), antibodies to the rubella virus in 83.9% (161/192) and evidence of toxoplasma infection in 77.1 % (148/192). Of the 38 HBsAg-positive subjects, 5.2% and 55.3% were positive for the HBe antigen and HBe antibody, respectively. We found a high prevalence of these infections in the antenatal clinic attendants. The data will be used to develop an appropriate control strategy for them.
