KEMRI Housing Cuts Malaria Risk

S 1 - 2 D I ID RK RT C - 0

Scientists at the Kenya Medical Research Institute reported that low-cost housing modifications reduced indoor heat and malaria risk in rural western Kenya. A randomized pilot study in Siaya County found electricity-free changes lowered indoor temperatures by up to 3.3°C and cut malaria-carrying mosquitoes by 77%. Interventions included reflective roofs, cross-ventilation, and mat ceilings with full screening. Researchers said the approach complements bed nets and supports climate adaptation. The findings inform public health housing policy.
