The diagnosis of some infectious diseases contracted during pregnancy is very important, as these diseases can be transmitted to the fetus. Four hundred and eighty-one pregnant women were studied, of an average 24.5 years of age (from 14 to 46), during their first prenatal visit to the State of S. Paulo's Health Care Centres in the subdistrict of Paz (Butantan), City of S. Paulo, Brazil, between April and October, 1988. Classified by trimester of pregnancy, 230 patients (47.8%) fell into the first, 203 (42.2%) into the second and 48 (10%) into the third trimester. Of the 474 patients that declared their income, 309 (65.2%) earned 1 MSPC (minimum salary per capita) per month, which gives some indication of the low socioeconomic status of our patients is. The serologic tests for syphilis, toxoplasmosis and Chagas' disease were analysed for each patient, more than one technique being used for each. The results were as follows: 25 patients (5.2%) had a positive test for syphilis; in 67 patients (13.9%) active toxoplasmosis was diagnosed (Presence of IgM antibodies in 6); 14 patients (2.9%) were positive for Chagas' disease, among which 10 (71.4%) came from the States of Bahia and Minas Gerais, where this disease has a high prevalence.
