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.
在哥伦比亚，恰加斯病的病原体克氏锥虫的主要传播媒介是长红猎蝽和二色锥蝽。二色锥蝽在哥伦比亚东部地区以家栖、近家栖和野生种群的形式存在，这给其防治带来了困难。一种经济有效的房屋处理优先排序方法是根据风险因素对房屋进行分层。在本研究中，评估了风险因素与二色锥蝽住所感染之间的潜在关联。与混合屋顶（优势比[OR]=36.14，95%置信区间[95%CI]=12.21-106.97）、猫（OR=3.94，95%CI=1.36-11.38）、石堆（OR=5.28，95%CI=1.64-16.98）以及高度超过10米的灌木丛（OR=11.21，95%CI=2.08-60.45）的存在相关的是家栖感染可能性增加。这些因素可用于将二色锥蝽的监测和防治目标锁定在感染风险增加的房屋上。
