Med Biotech is a research-focused NGO based in Kampala, Uganda, that has developed Home Decoration for Malaria Control (HD4MC), which adapts the customary practice of plastering the walls of mud-walled homes with soil by mixing in World Health Organization-approved insecticide and using this insecticide-mixed soil to plaster walls for household vector control. Funding will be used for field testing to assess the safety and efficacy of HD4MC, which will enroll 420 households and an estimated 2,100 people across ten villages in northern Uganda, generating critical data to support the use of HD4MC for vector control and malaria transmission.
