Control of Zika transmission using low-cost transfluthrin repellent emanators
Existing repellent products are designed for middle and high income country markets, where users can afford to replace or retreat them every day, week, or month. However, these are too expensive and impractical for routine use in communities of low-income countries.
We recently developed a low-technology emanatory which releases repellent transfluthrin vapour more slowly, to provide protection against mosquitoes for months or even a year at a time. Thus far however, this device has only been assessed against night-biting vectors of malaria and filariasis. The overall goal of this study is therefore to repeat these assessments of efficacy for the day-biting Aedes aegypti, the most globally important vector of Dengue, Chikungunya and Zika. The project will be implemented in Dar es Salaam, where Aedes aegpti is abundant and has been responsible for Dengue epidemics.
