S5. Transmission potenital (Index P) data

Transmission potential (index P) quantifies the risk of dengue virus transmission in a specific region, taking into account climate-based factors such as temperature and humidity, which directly influence the breeding, survival, and biting behaviour of the mosquito vectors responsible for spreading the virus. This index provides insight into how favourable environmental conditions are for dengue circulation in a given area. The spatio-temporal estimates of transmission potential for African countries and territories used in this review were developed by Nakase et. al (2023) .
