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.
