Using low-cost mosquito repellent chairs to provide day and night protection against mosquito borne illness

Objectives

Protecting people against mosquito bites before bedtime is still a challenge. This project aims at testing the concept of using chairs fitted sisal spatial mosquito repellent as a tool against mosquito bites which occur before going to sleep underneath a protective bed net.

In the timeframe of 12 months, this project intends to achieve the following objectives;

1. To design and create prototypes of highly scalable, low-cost and fashionable chairs treated with area-wide transfluthrin mosquito repellents that last for at least 6 months
2. To determine the minimum dose (D_m) of transfluthrin required for the chair prototype in objective 1 to provide > 80% protection against malaria free laboratory reared Anopheles arabiensis mosquitoes and arbovirus- free laboratory reared Aedes aegypti mosquitoes in large cage experiments for at least 3 months, and in real life situation against several taxa of mosquitoes.
3. This study will also enable to determine the retreatment frequency.
4. Assess the perception of repellent chairs and the willingness to use this proposed intervention, and their perceived cost
