Global warming is expected to exacerbate heat-related illness, especially in Africa. This not only has an impact on an individual’s health, but also their ability to work, and therefore reduces the economic productivity at a community level.

Dr Abong’o will lead a team investigating the effectiveness of simple housing modifications, assessing their impact on cooling internal temperatures as well as their ability to lower the incidence of malaria by preventing indoor entry of mosquitoes.
