Seroprevalence and risk factors for Toxoplasma infection in pregnant women in Jordan.

To determine the seroprevalence and risk factors for toxoplasmosis among pregnant women in Jordan, sera from 280 pregnant women were tested during the period January 2000-May 2001. Blood samples were taken after the first antenatal visit. Serum was separated and tested for Toxoplasma IgG antibodies using an indirect fluorescent antibody. Seroprevalence gradually increased with age, from 31.7% at 15-24 years to 90.0% at 35-45 years. Regression analysis showed that seroprevalence of toxoplasmosis is positively correlated with age and residence. Consumption of undercooked meat and contact with soil were significant risk factors.
