Description
Summary:Acute infections by the protozoan Toxoplasma gondii during pregnancy (gestational toxoplasmosis) are known to cause serious health problems to the fetus (congenital toxoplasmosis). In Brasília, there have been few studies on the incidence of toxoplasmosis. This report summarizes a retrospective study performed on 2,636 selected pregnant women attended by the public health system of Guará, a satellite-city of Brasília. In this survey, 17 cases of gestational toxoplasmosis were detected; 15 of which were primary maternal infection and the remaining 2 were consistent with secondary maternal infection. These results suggest an annual seroconversion rate of 0.64 percent (90 percent confidence interval: 0.38, 0.90). Infecções agudas pelo protozoário Toxoplasma gondii durante a gravidez (toxoplasmose em gestantes) são conhecidas por causar sérios problemas de saúde ao feto (toxoplasmose congênita). Em Brasília, estudos sobre a incidência da toxoplasmose são escassos. Este relato resume um estudo retrospectivo realizado com um grupo selecionado de 2.636 gestantes assistidas pelo sistema público de saúde do Guará, cidade-satélite de Brasília. Nesta investigação, foram detectados 17 casos de toxoplasmose gestacional; 15 dos quais casos de infecção materna primária, e os 2 restantes consistentes com infecção materna secundária. Estes resultados sugerem uma taxa de soroconversão anual da ordem de 0,64 porcento (intervalo de confiança de 90 porcento: 0,38; 0,90).
