Overview

Randomized trial evaluates triatomine presence and infection in Brazil, highlighting ongoing transmission risks.

Key Points

  • To assess triatomine population dynamics and identify high-risk areas for Trypanosoma cruzi transmission in Rio Grande do Norte, Brazil.
  • Evaluated vector control and entomological indicator activities across different mesoregions from 2005 to 2022.
  • Analyzed secondary data of triatomine captures in domiciliary units from multiple municipalities.
  • Conducted active searching and entomological surveillance in domestic environments.
  • High infestation index recorded in the West and Central mesoregions.
  • Triatoma brasiliensis and Triatoma pseudomaculata were the most frequently captured, with the West exhibiting the greatest diversity.
  • Elevated natural infection index by Trypanosoma cruzi observed in all three mesoregions.
