Epidemiological profile of acute Chagas disease in the northern region during the period from 2020 to 2024

Abstract

Objective: Present the epidemiological profile of acute Chagas disease in the northern region of Brazil, between the years 2020 and 2024. Methods: The study consists of an ecological, retrospective, observational, and descriptive research with data from SINAN. Results: Between the years 2020 and 2024, the northern region accounted for 95.71% of national notifications, with the most prevalent states being Pará (86.42%) and Amapá (8.21%). The sociodemographic profile shows a predominance of self-declared brown individuals (85%), males (54%), aged 20 to 39 years (34.31%). A marked social vulnerability was observed, evidenced by low education levels, particularly incomplete primary education (17.31%). Oral transmission established itself as the main route of infection (90.94%). Diagnosis was predominantly based on laboratory criteria (94.05%). Regarding clinical progression, the condition showed low fatality, with a survival rate of 90.05%. Conclusion: We concluded that DCA in the Northern Region has a strong occupational and socio-environmental character, requiring the implementation of localized public policies focused on health education for agro-extractive populations and on strengthening Primary Health Care to mitigate outbreaks and enable early diagnosis.
