Abstract

Toxoplasmosis is a parasitic disease caused by infection with the protozoan Toxoplasma gondii. In 2018, the first cases of people with clinical signs of acute febrile syndrome were reported, and in the same year, the largest outbreak of human toxoplasmosis ever described in the literature was reported. In this sense, the present work sought to describe the evolution of the outbreak cases in the municipality of Santa Maria, Rio Grande do Sul State, Brazil, as well as the studies conducted and published during and after the outbreak in the municipality (the period between 2018 and 2023). In addition, the discussion of public policies and their modifications after the notification of this outbreak. As a result of this research, verifying the evolution of notified and confirmed cases, the possibility of detection and genotypic characterization of T. gondii and the possibility of co-infections and evaluation of the humoral response is possible. With regard to public policies, the importance of detecting the agent through the heel prick test and increasing the monitoring of water quality to prevent outbreaks.
