This research was carried out in both domestic and wild environments throughout a Northeastern rural locality. Triatomines were captured in both peridomicile and wild environments, obtaining 508 specimens of triatomines, of which 99.6% were <jats:italic>Triatoma brasiliensis<\/jats:italic>. Insects were captured in 10 (18.5%) peridomiciles with an average of 8.3 triatomines per residence. <jats:italic>Triatoma brasiliensis<\/jats:italic> nymphs and adults were found in six peridomiciles, generating a 11.1% colonization. No <jats:italic>T. cruzi<\/jats:italic> infection was detected in the 447 peridomestic insects analyzed. On the other hand, of the 55 sylvatic <jats:italic>T. brasiliensis<\/jats:italic> molecularly examined for <jats:italic>T. cruzi<\/jats:italic>, 12 (21%) were positive, all harboring <jats:italic>T. cruzi<\/jats:italic> I. The blood meal analysis by enzyme-linked immunosorbent assay from gut content revealed that both peridomestic and wild triatomine populations fed mainly on birds, refractory to the parasite, which may explain the null rate of natural infection prevalence in the domestic environment. However, infected triatomines for potential home infestation within the radius of insect dispersion capacity were registered in rock outcrops around the dwellings. Anthropogenic environmental influences are able to rapidly alter these scenarios. Therefore, to avoid disease transmission to humans, we recommend constant vector control combined with periodic serological surveillance. The associated methodology presented herein may serve as a model for early detections of risk factors for Chagas disease transmission in the Brazilian Northeast.<\/jats:p>","DOI":"10.4269\/ajtmh.18-0480","type":"journal-article","created":{"date-parts":[[2019,2,7]],"date-time":"2019-02-07T07:14:43Z","timestamp":1549523683000},"page":"296-302","source":"Crossref","is-referenced-by-count":9,"title":["Multiple Approaches to Address Potential Risk Factors of Chagas Disease Transmission in Northeastern Brazil"],"prefix":"10.4269","volume":"100","author":[{"given":"Natalia Faria","family":"Daflon-Teixeira","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Ecoepidemiologia da Doen\u00e7a de Chagas, Instituto Oswaldo Cruz, IOC\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carolina","family":"Coutinho","sequence":"additional","affiliation":[{"name":"Instituto de Comunica\u00e7\u00e3o e Informa\u00e7\u00e3o Cient\u00edfica e Tecnol\u00f3gica em Sa\u00fade\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ta\u00eds Ferreira","family":"Gomes","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Ecoepidemiologia da Doen\u00e7a de Chagas, Instituto Oswaldo Cruz, IOC\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena Keiko","family":"Toma","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Diagn\u00f3stico Molecular e Hematologia, Universidade Federal do Rio de Janeiro (UFRJ), Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosemere","family":"Duarte","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Biol\u00f3gicas, Escola Nacional de Sa\u00fade P\u00fablica (ENSP)\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00e1rcio Neves","family":"B\u00f3ia","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Biologia e Parasitologia de Mam\u00edferos Silvestres Reservat\u00f3rios, IOC\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filipe Anibal","family":"Carvalho-Costa","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Epidemiologia e Sistem\u00e1tica Molecular, IOC\/Fiocruz, Rio de Janeiro, Brazil;"},{"name":"Escrit\u00f3rio Regional Fiocruz Piau\u00ed, Funda\u00e7\u00e3o Oswaldo Cruz, Teresina, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Eduardo","family":"Almeida","sequence":"additional","affiliation":[{"name":"Instituto de Biologia, Universidade Estadual de Campinas, Unicamp, Campinas, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marli Maria","family":"Lima","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Ecoepidemiologia da Doen\u00e7a de Chagas, Instituto Oswaldo Cruz, IOC\/Fiocruz, Rio de Janeiro, Brazil;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Parasitol Res","first-page":"1687","article-title":"Chagas disease and housing improvement in northeastern Brazil: a cross-sectional survey","volume":"114","author":"Lima","year":"2015"},{"key":"b2","series-title":"World Health Popul","first-page":"14","article-title":"Reasons for persistence of dwelling vulnerability to chagas disease (American trypanosomiasis): a qualitative study in northeastern Brazil","volume":"14","author":"Gomes","year":"2013"},{"key":"b3","series-title":"Cad Saude Publica","first-page":"S35","article-title":"Situa\u00e7\u00e3o do controle da transmiss\u00e3o vetorial da doen\u00e7a de chagas nas Am\u00e9ricas","volume":"16","author":"Silveira","year":"2000"},{"key":"b4","series-title":"Mem Inst Oswaldo Cruz","first-page":"1009","article-title":"Morbidity of chagas heart disease in the microregion of Rio Negro, Amazonian Brazil: a case-control study","volume":"108","author":"Coura","year":"2013"},{"key":"b5","series-title":"Vetores da Doen\u00e7a de Chagas no Brasil","first-page":"289","author":"Galv\u00e3o","year":"2014"},{"key":"b6","series-title":"Rev Saude Publica","first-page":"999","article-title":"Biogeografia, origem e distribui\u00e7\u00e3o da domicilia\u00e7\u00e3o de triatomineos no Brasil","volume":"40","author":"Forattini","year":"2006"},{"key":"b7","series-title":"Mem Inst Oswaldo Cruz","first-page":"11","article-title":"Southern Cone Initiative for the elimination of domestic populations of Triatoma infestans and the interruption of transfusional chagas disease.
