[Seroepidemiology of toxoplasmosis in pregnant women and neonatal infants].

A serological screening among pregnant females for toxoplasmosis in the Belgorod Region has shown a rise in the incidence of this infection in them during seven years (1996-2002). There is also a more than 2-fold increase in the rate of Toxoplasma infection by the second trimester. This increases a risk for fetal congenital malformations and the severity of neonatal congenital malformations. Different awareness levels are shown in fertile-age females from different administrative areas of the region.
