Low-tech Treated Fabric for Outdoor Use

Testing Transflutherin-treated Fabric for Protection from Mosquitoes Outdoors

Organization: Liverpool School of Tropical Medicine

Location: Liverpool, United Kingdom

Problem: Existing repellents are too expensive and impractical for continuous, indefinite use. New, affordable, rapidly scalable repellent products are urgently needed to protect at-risk populations against mosquito-borne pathogens.

Solution: This simple, affordable low-tech transfluthrin emanator provides more than 90% protection for over 6 months against nocturnal Anopheles and Culex mosquitoes. This project will test it against Aedes populations. The emanator costs only $0.15, and uses widely-available Hessian fabric, which can be treated and re-treated safely by any individual, community, program or local manufacturer.

"After struggling for years to develop a practical, affordable technology to protect poor rural African communities against outdoor exposure to malaria vector mosquitoes, we finally feel we’ve got something here that really is fit for purpose, for which simultaneous protection against Zika, Dengue and Chikunungunya was an obvious spin-off application. The global Zika pandemic emerged just after we had made our most critical breakthroughs with these prototype transfluthrin emanators, so I felt we were well placed to offer something practical and rapidly scalable to address this new and deeply worrisome challenge. I also felt Haiti was an important country to work with on this project, because it has perhaps the greatest needs and challenges in the Americas, and will test the technology to its limits."

"I was born and raised in a malaria endemic area in rural Western Kenya and I felt the need to join the fight against malaria by studying the disease and finding ways to prevent bites. Evidently, increased use of bed nets has reduced malaria cases considerably but efficacy is undermined by vectors that avoid bed nets by feeding and resting outdoors. We therefore developed a simple and practical low-technology emanator that can be used by people living in rural areas to protect against a range bites of mosquito-borne diseases including Zika, malaria, Dengue and Chikungunya that mainly bite outdoors where effective long-term personal protection tools are lacking."
