[Chronic toxoplasmosis in pregnant women--an epidemiological and social problem].

Frequency of pregnancy miscarriage was analized in 52 women with chronic toxoplasmosis treated clinically. The pregnancy miscarriage was found in 78.4% of cases including abortion-48.7%, premature and immature delivery resulting in death-17.1% and newborns with congenital defects-12.6%, of with 78.6% died shortly after the delivery. The percentage of normal pregnancy amounted to 21.6% and in 3 cases newborns with congenital defects survived.
