Análise dos casos de leptospirose no âmbito nacional, estadual e do município de Governador Valadares-MG

Abstract

Human leptospirosis is a disease caused by a spirochete of the genus Leptospira. Although it is potentially lethal, its impact on the health of the population is still underestimated. The objective of this work was to evaluate the occurrence of leptospirosis cases nationwide in the state of Minas Gerais (MG) and the municipality of Governador Valadares (GV) based on data obtained from the information system for notifiable diseases (SINAN) – DATASUS , in order to carry out a dynamic diagnosis of this infection in the three spheres. An observational, retrospective study was carried out considering the period from january 2007 to december 2020. The data obtained for Brazil (BR) and MG were compared with those for GV, considering age group, race, sex, education, diagnostic criteria, evolution of the disease, among others. 50,912 cases of Leptospirosis in BR were observed, 1,876 (3.7%) in MG and 33 (0.064%) in GV. leptospirosis affects a population, predominantly, of working age, male and with low education. The majority of cases occurred in urban areas, in the home environment and mainly during periods of greatest rainfall and flooding. The clinical-laboratory criterion was the most used to confirm cases, which, in the majority, progressed to cure. This work highlighted the need for investment in public policies that promote better sanitary conditions for the population, better drainage and management of rainwater with a reduction in flooding during rainy periods and information for the population regarding preventive measures and control of this disease.
