[Congenital toxoplasmosis in the Poznan region].

Among 3,734 women, hospitalized for giving birth, 58.9% had a positive Toxoplasma serological test (DA). No clinical expression of congenital toxoplasmosis was observed in 4,311 newborns; seven had a false positive ISAGA test with cord blood. Only 24% of the women were aware of congenital toxoplasmosis and only 3% were serologically examined before. Health education should be intensified and serological tests more commonly performed especially in the risk groups.
