Nudge toward malaria elimination – development of novel integrated strategy in tropical Africa

This study will examine mass medication including ivermectin, and economic incentives to minimize the risk of infection and “nudge” the population to receive early diagnosis and treatment if symptoms develop. Through a strategy that integrates these two and multifaceted monitoring, the aim is to suppress the residual transmission of malaria in target areas and to prove the concept of the proposed comprehensive community-led malaria eradication strategy in tropical Africa.
Eradication of malaria is a task for humanity in the 21st century. Despite the recent scale-up of insecticide-treated mosquito nets and artemisinin-based combination therapy, high levels of transmission continue in many tropical African malaria-endemic areas. As factors supporting this residual transmission, it was found that (1) the existence of many asymptomatic infected persons, (2) insecticide-resistant outdoor blood-sucking vector mosquitoes, and (3) inappropriate behavior of residents to prevent infection. rice field. The purpose of this research proposal is not only to suppress these residual transmissions, but also to demonstrate the concept of a comprehensive and community-led malaria eradication strategy in tropical Africa that aims to eradicate malaria. As an approach, we seek the fusion of medical science and behavioral economics, and propose a new academic field that can be called “behavioral medical science.” This year, based on the preliminary survey, we started an intervention test. The target area is Suba South Sub-County in the area surrounding Lake Victoria, Kenya. The intervention was based on a behavioral economics approach, with a scheme that rewards households for achieving malaria control. Regarding the payment method of incentives, there is a plan (Conditional Cash Transfer) that uniformly pays households that achieve their goals, and a plan that allows them to participate in a lottery where they can receive a large reward (Lottery Incentive Scheme). In order to promote appropriate preventive behavior based on these incentives, we conducted community health education using an e-learning system on correct and effective malaria preventive behavior and improvements to the current situation before intervention. The intervention is being developed as a cluster-randomized controlled trial utilizing a community health volunteer system. A household survey was conducted prior to the intervention to determine study clusters, and a large cross-sectional survey of pre-intervention malaria infection rates was conducted.
