Introduction:

toxoplasmosis is a zoonotic infection caused by Toxoplasma gondii, an intracellular protozoan that can affect children of pregnant women and cause severe sequelae; therefore, serological monitoring should be performed.

Objective:

to determine the prevalence of low avidity IgG anti-Toxoplasma gondii and the risk behavior for toxoplasmosis disease in pregnant women during the 2017-2019 time period, who attended the Health Sciences Research Institute of the Universidad Nacional de Asuncion - Paraguay.

Methodology:

a total of 371 patient records with positive IgG serology for toxoplasmosis, whose samples were processed in the Production Department of the Instituto de Investigaciones en Ciencias de la Salud between the years 2017-2019 were analyzed. Subsequently, in 2020, 149/371 digital surveys of the same women were conducted on their knowledge and risk behavior for toxoplasmosis.

Results:

a low avidity prevalence of 18 % for toxoplasmosis was observed. 98 % knew about the disease, 73 % acquired information during pregnancy, and 50.3 % received preventive orientation. 65 % reported that eating undercooked meat and raw vegetables is a form of disease transmission. Regarding risk behavior, 46 % of the participants consumed poultry, 20 % consumed medium-rare-cooked meat, and 78 % consumed raw vegetables. Fifty-four percent of the patients performed farming activities, 44.3 % had cats as pets, 82 % had dogs, and 9 % slept with their pets.

Conclusion:

some risk behaviors for toxoplasmosis were evident in the women surveyed, demonstrating the need to implement primary prevention programs in our country.
