<i>Toxoplasma gondii</i> seroprevalence in the Portuguese population: comparison of three cross-sectional studies spanning three decades

Abstract

The scenario observed for the latter indicates that more than 80% of childbearing women are susceptible to primary infection yielding a risk of congenital toxoplasmosis and respective sequelae. Since there is no vaccine to prevent human toxoplasmosis, the improvement of primary prevention constitutes a major tool to avoid infection in such susceptible groups.
