Seroprevalence of toxoplasmosis and rubella in pregnant women attending antenatal private clinic at Ouagadougou, Burkina Faso

ObjectiveTo evaluate the prevalence of toxoplasmosis and rubella among pregnant women at Ouagadougou in Burkina Faso.MethodsAll patient sera were tested for rubella and toxoplasmosis anti-IgG using commercial ELISA kits (Platelia™ Rubella IgG and Platelia™ Toxo IgG). The presence of anti-rubella and anti-toxoplasmosis IgM in serum samples was tested using commercial ELISA kits Platelia Rubella IgM and Platelia Toxo IgM.ResultsAmong all the pregnant women tested for toxoplasmosis and rubella, their prevalence were 20.3% and 77.0%, respectively. Pregnant women in the age group of 18-25 years showed the highest frequency of anti-toxoplasmosis (34.5%) and anti-rubella IgG (84.6%). The prevalence of anti-toxoplasma and anti-rubella IgG decreased between 2006 and 2008 from 32.7% to 12.1% and 84.6% to 65.0%, respectively. There was no significant association between age and the mean titer of anti-toxoplasmosis IgG among pregnant women.ConclusionsThe diagnosis of toxoplasmosis and rubella is necessary in pregnant women in Burkina Faso because of the low immunization coverage rate of rubella and the high level of exposure to these two infections which can be harmful to the newborn if contracted by women before the third trimester of pregnancy.
