ABSTRACT
Background:
We assessed the distribution of triatomines in an endemic area for Chagas disease.
Methods:
This retrospective study used secondary data extracted from the Official System of the National Chagas Disease Control Program (Sistema Oficial do Programa Nacional de Controle da Doença de Chagas - SisPCDCh).
Results:
A total of 7,257 (725.7 ± 221.7 per year) specimens were collected from 2013 to 2022. Most of them (6,792; 93.6%) were collected in the intradomicile and 465 (6.4%) in the peridomicile. A total of 513 (7.1%) triatomines tested positive for the presence of trypomastigote forms, similar to Trypanosoma cruzi.
Conclusions:
The spatial analysis revealed a heterogeneous distribution of triatomines across different municipalities.
