Chagas disease is a major vector-borne disease, and regional initiatives based on insecticide spraying have successfully controlled domiciliated vectors in many regions. Non-domiciliated vectors remain responsible for a significant transmission risk, and their control is a challenge. We performed a proof-of-concept field trial to test alternative strategies in rural Yucatan, Mexico. Follow-up of house infestation for two seasons following the interventions confirmed that insecticide spraying should be performed annually for the effective control of Triatoma dimidiata; however, it also confirmed that insect screens or long-lasting impregnated curtains may represent good alternative strategies for the sustained control of these vectors. Ecosystemic peridomicile management would be an excellent complementary strategy to improve the cost-effectiveness of interventions. Because these strategies would also be effective against other vector-borne diseases, such as malaria or dengue, they could be integrated within a multi-disease control program.
恰加斯病是一种主要的虫媒传染病，基于杀虫剂喷洒的区域性举措已成功控制了许多地区的家庭饲养媒介。非家庭饲养媒介仍然存在重大的传播风险，对其进行控制是一项挑战。我们在墨西哥尤卡坦州的农村地区进行了一项概念验证实地试验，以测试替代策略。干预措施实施后的两个季节对房屋滋生情况的跟踪调查证实，每年进行杀虫剂喷洒是有效控制 Tdimidiata 的方法；然而，它也证实了防虫网或长效浸渍窗帘可能是这些媒介持续控制的良好替代策略。生态系统周边环境管理将是提高干预措施成本效益的绝佳补充策略。由于这些策略对疟疾或登革热等其他虫媒传染病也同样有效，因此它们可以整合到多疾病控制计划中。
