Toxoplasmosis in Serbia: time for an action plan*

Abstract

Known for a century, Toxoplasma gondii has been studied in Serbia half this time, ever since the introduction of the Sabin-Feldman test at the Institute for Medical Research (IMR) in 1959. However, despite 50 years of continuous efforts, exact data on the frequency of acute clinical disease, acute infections in pregnancy and congenital infection in the offspring are still lacking, due to the vague regulatory provision that toxoplasmosis is subject to reporting “in case of epidemiological indications”. It is, however, clear that the major Toxoplasma-induced public health issue in Serbia, like elsewhere in Europe, is congenital toxoplasmosis (CT). Continuous monitoring of particular patient groups showed a dramatic decrease in the prevalence of infection over the past two decades, and a consequently increased proportion of women susceptible to infection in pregnancy, suggesting a potential increase in the incidence of CT. Studies of risk factors for infection transmission have provided data to guide national health education campaigns. It is expected that the recent appointment of the National Reference Laboratory for Toxoplasmosis as the focal point for the collection of data from the primary level, will provide the means for accurate assessment of the measure of the problem, which is a prerequisite of an evidence-based nation-wide prevention program. In the meantime, health education of all pregnant women, focused at risk factors of major local significance, is advocated as a sound and financially sustainable option to reduce congenital toxoplasmosis.
