“…It is estimated that 6 to 7 million people worldwide are infected, and the disease is found mainly in endemic areas of continental Latin American countries (MEDEIROS, 2022). Although triatomine insects are the primary vectors of CD transmission, the oral route through contaminated food was considered the main means of transmission in the Brazilian Amazon (ORTIZ, 2021). Oral transmission has been associated with the consumption of food contaminated with triatomines, their feces, or the ingestion of raw or undercooked meat from reservoirs of infected wild mammals.…”

Chagas disease (CD) is caused by the protozoan Trypanosoma cruzi, whose transmission involves triatomine insects. However, in the Brazilian Amazon there is a predominance of oral transmission through the ingestion of food contaminated with Trypanosoma cruzi. Brazil is one of the largest endemic centers of Chagas Disease in Latin America, and this disease is associated with human actions. An ecological, crosssectional and retrospective study was designed. The number of diagnosed cases of Chagas Disease in the states of the Brazilian Amazon from 2009 to 2019 were analyzed. The North Region had 2,832 cases of CD in the period in question, corresponding to 94.3% of the total cases in the country. Pará was the state with the highest number of cases (2,251), followed by Amapá (161) and Amazonas (138). Oral transmission was the main means of transmission (76.2%), followed by vectorial (8.43%) and vertical (0.39%). In this scenario, the consumption of açaí was the factor associated with the highest number of cases in the region, since the pulp of this food can be contaminated by waste from reservoir animals or vectors. Thus, the handling of açaí must be carried out properly to prevent this public health problem. Still, it is necessary to carry out further studies in the affected regions, evaluating such preventive measures.

ObjectivesThis study aims to provide a comprehensive analysis of clinical and epidemiological data related to Chronic Chagas Cardiomyopathy (CCC) in the Amazon region of Brazil.MethodsA review of observational, retrospective, and cross-sectional studies related to Chagas Disease in the Amazon region of Brazil was conducted, and a case series addressing CCC in patients treated at the FMT-HVD outpatient clinic, a reference center for Chagas disease in Brazil, was carried out.ResultsClinical characteristics of 55 patients from the Amazon region with CCC were described. The most common electrocardiographic alteration observed was abnormal ventricular repolarization (AVR), present in 40% of cases. The most common echocardiographic finding was left ventricular systolic dysfunction (49%), followed by akinesia or hypokinesia of the inferior and/or inferolateral walls (38.1%) and the presence of an apical aneurysm (32.7%).ConclusionsOverall, this study demonstrates that CCC in the Amazon region presents clinical characteristics and severity that are similar to those observed in other regions. However, certain peculiarities, such as the frequency of right bundle branch block (RBBB) and anterior and septal involvement during the acute phase, require additional investigation to better comprehend the disease in the region. Overall, the study provides crucial clinical insights for the diagnosis and treatment of CCC in the Amazon region.
