  1. Models for prediction of the frequency of toxoplasmosis in pregnancy in situations of changing infection rates.

    Article - En anglais

    Background

    Estimation of the number of women infected during pregnancy with Toxoplasma gondii from seroconversion or seroprevalence data meets with various difficulties.

    Because of the high risk of transmission of the infection to the fetus such infections are however a major concern in pregnancy-related health planning.

    Methods

    The expected annual percentage of pregnant women infected with Toxoplasma was calculated using models with varying assumptions with regard to the infection rate, assumed to be independent of age but dependent on calendar time.

    Three situations were studied : a stable situation, a sudden fall in the infection rate and a gradually declining (slower or faster) infection rate over the lifetime of the pregnant women.
