Salvador, BA, BrasilFollowing reports of an unusually high incidence of acute Chagas’s disease and the appearance of large numbers of Triatoma infesrans in the southwestern region of the State of Bahia, triatomine bugs (Hemiptera: Reduviidae) and domestic animals in one of the affected communities were surveyed and examined for infection with Trypanosoma cruzi. Triatoma infestans was prevalent in houses and was also found in peridomestic habitats. T. sordidu and T. pseudomaculata occupied peridomestic and svlvatic habitats and T. brasiliensis was found onlv , among rocks far from houses. Panstrongylus megistus, formerly present in the region, was not found. Trypanosoma cruzi was detected in 19.5 ‘Iii of Triatoma infestans, 11.5”,, of T. sordida, 19”,, of dogs, 29:,, o f cats and 100” u of rats examined. A dlsproportionate number of early instar bugs were infected with Trypanosoma cruzi, suggesting that a rapid increase in the rate of transmission had recently occurred. The history of the domestic triatomine fauna of the region since 1912 is reviewed, and it is proposed that the relatively recent arrival of Triatoma infestans initiated a domestic cycle linked to peridomestic and sylvatic cycles of’ TryDanosoma cruzi transmission. Increased human mobility, the use of DDT for malaria control. and drought conditions are considered as factors which miiht have contributed to the outbreak of human infection.engOxford University PressDoença de ChagasTriatomaTriatomíneosTrypanosoma cruziPanstrongylusAnimaisRatosTransmissãoAn outbreak of acute Chagas’s disease in the Sao Francisco Valley region of Bahia, Brazil : triatomine vectors and animal reservoirs of Trypanosoma cruziinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZLICENSElicense.txtlicense.txttext/plain;
