Abstract
INTRODUCTION:
This retrospective study conducted from 2001 to 2018 investigated the residual foci of Triatoma infestans infestation in Rio Grande do Sul, Brazil.
METHODS:
The data were obtained via entomological surveillance and the distribution of vector occurrence. The coverage of active research was mapped.
RESULTS:
The largest coverage rate for active research was observed in the northwest region of the total of 515,081 domiciles researched. Most T. infestans specimens were captured in the peridomicile.
CONCLUSIONS:
Infestation has decreased significantly since 2008, and T. infestans has not been captured since 2015.
