Low-cost Treated Sandals

Transfluthrin-treated Sandals For Providing Round-the-clock Protection Against Mosquito Bites

Organization: Ifakara Health Institute

Location: Ifakara & Dar es Salaam-Tanzania, Minas Gerais & Belo Horizonte - Brazil

Problem: Mosquito-borne diseases such as Malaria, Dengue, Chikungunya, and Zika present major public health and global security concerns. Interventions like long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) have jointly contributed about 78% of all gains made against malaria since 2000. However, these interventions have proven insufficient due to the fact that they mostly target night and indoor biting mosquitoes leaving people unprotected for the most part of the day. Additionally, many mosquitoes have developed resistance to the insecticides commonly used in these interventions.

Solution: Mosquitoes predominantly bite people around the feet and ankles. Protecting the lower limbs of individuals has been proven to prevent two thirds of mosquito bites. In this project we are exploiting this mosquito behaviour by using footwear as a platform to release highly effective wide-area spatial mosquito repellents, thereby creating full-time protection against both day-biting and night-biting mosquitoes at individual and household level. We have designed and developed a new line of footwear treated with spatial repellent, transfluthrin that is highly effective against both day and night-biting mosquitoes.

"Even though current tools have had a great impact on malaria transmission, they are unable to eliminate this disease. The motivation for this project was to develop a tool that could offer complete protection, is simple to use, and cost effective."
