Insect vectors of Chagas disease (Trypanosoma cruzi) in Northeastern Brazil

Abstract: These results verify the presence of triatomines in both intra- and peridomiciliary areas, thereby ensuring persistence of the pathogen and consequently, the disease, as the presence of infected vectors in households is an important risk factor. According to these findings, the Chagas Disease Control Program should intensify its efforts in order to prevent the spread of the disease.

“…In this municipality, estimated seroprevalence rates of 2.6% (4/154) and 4.2% (34/812) were observed in 2011 and 2013, respectively 6,7 . This region presents a high risk of vectorial transmission due to the high rate of natural infection by T. cruzi (estimated in 7.9%) in triatomines 8 .…”

“…The dispersion of triatomines in different environments may be related to mating or a search for food 19 . In this study, the presence of nymphs intradomicile indicates the formation of colonies in these environments represented by the phenomenon of domiciliation, and consequently high risk for human infection 7,12 .…”

“…In Brazil, the presence of these reduvids has been reported in different regions, since they are adapted to distinct ecotypes 5,6 . These specimens may live in intradomiciliary and peridomiciliary environments 7,8 . Peridomiciliary ecotypes, including animal facilities and building remains, play an important role as a bridge between the domestic and wild cycles of the disease 8,9 .…”
