Resumo
Toxoplasmosis is one of the most prevalent parasitic infections in humans, causing severe clinical
complications in immunocompromised patients or in foetuses. Estimates on the toxoplasmosis
seroprevalence in human populations vary widely, even within the same region. This study
aimed to estimate the prevalence of Toxoplasma gondii infection in the municipality of Santa
Cruz, State of Rio Grande do Norte, Brazil, and identify the risk factors for toxoplasmosis. T.
gondii IgG antibodies were measured in 66.2% of the studied population. The factors associated
with infection were as follows: age above 45 years (OR = 7.4; 95% CI = 3.7-14.8); illiteracy (OR
= 2.8; 95% CI = 1.6-5.0); the presence of more than three cats in the home (OR 2.0; 95% CI =
1.2-3.5); no water tank (OR = 2.0; 95% CI = 1.4-3.1); and consumption of raw or unpasteurized
milk (OR = 2.0; 95% CI = 1.3-3.0). The risk factors identified were predominantly related to the
ingestion of oocysts. This study may contribute to public health knowledge of toxoplasmosis and
the definition of control programs, particularly for pregnant women from regions similar to the
area studied.
