Vigilância entomológica da doença de Chagas no leste de Minas Gerais, Brasil.

Abstract

The Chagas Disease Control Program (PCDCh) is currently in the epidemiological surveillance phase in Brazil. One of the main challenges for PCDCh is to maintain and improve surveillance in the epidemiological area in which it is functioning. With the decentralization of health actions, transferring responsibilities for the control of endemic diseases to state and municipal governments in eastern Minas Gerais, the Regional Health Superintendence of Governador Valadares (SRS / GV) is responsible for the operation of the Program in 51 municipalities different. This study analyzes the current situation of the entomological surveillance of the disease in the SRS / GV, in order to understand and verify the functioning of the PCDCh notifications. From January to December of the years 2014, 2015 and 2016, 775 insects were captured, of which 680 adult triatomines and 19 nymphs were found in 46 different municipalities. Of these, 537 were examined for infection to Trypanosoma cruzi, where 256 were infected. The species present in this SRS are Triatoma vitticeps (443), Panstrongylus diasi (132), Panstrongylus megistus (99) and Rhodnius neglectus (6). The findings suggest that PCDCh is functioning in most SRS / if the question is asked in relation to the 05 silent municipalities, if they are even exempt from tritatomines or if the notification system has not worked in them.
