Abstract
- In Colombia, the main vectors of Trypanosoma cruzi, the causative agent of Chagas disease, are Rhodnius prolixus and Triatoma dimidiata. T. dimidiata is present in the east region of Colombia as domestic, peridomestic, and sylvatic populations, resulting in difficulties for its control. A cost-effective way to prioritize houses for treatment is to stratify houses based on risk factors. In this study, risk factors were evaluated for potential associations with domicile infestation of T. dimidiata. There was an increased likelihood of domestic infestation associated with the presence of mixed roofs (odds ratio [OR] = 36.14, 95% confidence interval [95% CI] = 12.21-106.97), cats (OR = 3.94, 95% CI = 1.36-11.38), rock piles (OR = 5.28, 95% CI = 1.64-16.98), and bushes with height above 10 m (OR = 11.21, 95% CI = 2.08-60.45). These factors could be used to target surveillance and control of T. dimidiata to houses with an increased risk of being infested.<br /> (© The American Society of Tropical Medicine and Hygiene.)
