Warming temperatures reduce lifespan and vectorial capacity of Anopheles mosquitoes in Ghana.

ABSTRACT: Climate change and variability are altering the ecology of malaria vectors, with implications for disease transmission in sub-Saharan Africa. In this study, we analysed long-term historical temperature, rainfall and relative humidity data across Ghana's climatic zones to evaluate their trends. We then incorporated these data into simple climate-driven biological models to assess how they impacted Anopheles mosquito lifespan, their Vectorial Capacity and Extrinsic Incubation Period of malaria parasites. This approach allowed us to assess the potential impacts of climate change on malaria transmission dynamics in the country. The analysis revealed, on the long-term, significant temperature warming (over 1.5°C), marked decline in relative humidity, and no clear trends in rainfall across all c
