Objetivo: O estudo objetivou avaliar o conhecimento da população adulta acerca dos vetores de doenças do Norte de Minas Gerais. Método: A pesquisa foi realizada na mesorregião Norte de Minas Gerais, Brasil, através das seguintes etapas: elaboração das perguntas, com base na literatura disponível; validação de conteúdo; montagem do jogo em uma plataforma on-line; teste piloto; correção do instrumento e aplicação. Para análise dos dados utilizou-se o programa IBM SPSS Statistics 25.0. Resultados: Houve a participação de 139 pessoas, com prevalência do público feminino, com idade superior a 31 anos e com ensino médio completo. Nenhum dos participantes conseguiu acertar todas as questões sobre os vetores. A questão que abordava as diferenças dos vetores Aedes aegypti e Culex quinquefasciatus, foi apontada como a mais difícil do jogo. Ao mesmo tempo, o índice de acerto foi maior em perguntas relacionadas à Aedes aegypti, piolhos e triatomíneos. Não houve associação significativa (p>0,05) entre as questões de identificação pessoal e dos vetores. Considerações finais: O jogo contribuiu compreender que a população adulta apresenta um conhecimento limitado sobre os vetores de doenças do Norte de Minas Gerais, além de transmitir informações sobre os vetores, como medidas profiláticas ao contágio e disseminação das zoonoses.
The north of the Brazilian state of Minas Gerais is classified as an area of high risk of vectorial transmission of Chagas disease (CD) or of reestablishing transmission in the home, but the Chagas disease control programme is disjointed. The study evaluated the occurrence, natural infection and the spatial distribution of species of triatomines associated with climatic variations in the urban area of Montes Claros, a municipality endemic to CD in the north of Minas Gerais, Brazil. Triatomine data were obtained from passive entomological surveillance actions of the Chagas Disease Control Program (Programa de Controle de Doença de Chagas—PCDCh), registered by the Zoonosis Control Center (Centro de Controle de Zoonoses—CCZ) from 2009 to 2019. A total of 277 triatomines belonging to eight species were collected, and of these, 203 insects were examined. It was found that 46.2% of triatomines were captured inside the home and 8.3% around the home. The natural infection rate was 6.9%; 14 specimens showed natural infection by Trypanosoma cruzi (12 females and 2 males), and of these, 13 were found in the home and one in an uninformed location. The number of triatomine records collected was significantly higher in the month of September (p = .01), and there was an inverse correlation between the number of triatomines and the relative humidity of the air (p < .001). It was verified that the highest triatomine densities are located in transition areas between urban infrastructure (32.12%) and pasture (25.72%). The diversity of species of triatomines infected with T. cruzi in residential units in urban areas in the municipality of Montes Claros is worrying, as it suggests a potential risk of transmission of the parasite to domestic animals and humans.
