Chagas disease is a parasitic infection transmitted by hematophagous insects popularly known as “barbeiros”, “chupão” or “chupança”. The World Health Organization estimates that approximately 6 to 7 million people are infected worldwide, the vast majority of whom are in Latin America. In Brazil, the northern region is responsible for almost all cases. The general objective of this study is to demonstrate the incidence of acute Chagas disease in the city of Belém/Pará in the years 2021 and 2022. The specific objectives are to determine the type of contamination, verify the seasonality and relate the seasonality to the type of contamination. This is an epidemiological, retrospective, and descriptive study that uses publicly accessible data from the Department of Information Technology of the Unified Health System on notifications of cases of acute Chagas disease reported in 2021 and 2022. Thirty-five cases of Chagas disease were confirmed in the municipality of Belém during the period studied; the main means of contamination was oral transmission, with 31 confirmed cases. The months of August to November represented the period of highest incidence of the disease, with an increase mainly in cases of oral contamination. These results are probably related to the increased consumption of food contaminated with Trypanosoma cruzi. We conclude that acute Chagas disease represents a public health problem and that it is being neglected in combat, treatment, and prevention actions.
