Distribution and natural infection status of synantrophic triatomines (Hemiptera: Reduviidae), vectors of < i > Trypanosoma cruzi < /i > , reveals new epidemiological scenarios for chagas disease in the Highlands of Colombia

ConclusionsAfter some municipalities were certified free of natural transmission within houses (intradomiciliary transmission) ofT.cruzi byR.prolixus,T.dimidiata has become the most prevalent vector present, and represents a significant risk of resurgent CD transmission. However,T.venosa,P.geniculatus, andP.rufotuberculatus also contribute to the increased risk of transmission. The presence of residualR.prolixus may undo the successes achieved through vector elimination programs. The molecular and spatial analysis used here allows us to identify areas with an ongoing threat of parasite transmission and improve entomological surveillance strategies.
