How humidity changes temperature-driven malaria risk in cities

Redefining thermal suitability for urban malaria transmission in the context of humidity

NIH-funded research Cornell University · NIH-11177918

This project looks at how humidity changes the way temperature affects city-dwelling malaria mosquitoes so public health teams can better predict urban malaria risk.

What this research studies

You will hear that researchers are running lab experiments on urban malaria mosquitoes to see how humidity modifies their ability to transmit malaria at different temperatures. They will combine those results with weather and city data to build computer models that map when and where malaria risk rises in specific neighborhoods. The team will compare model predictions to existing surveillance and case data to find hotspots and improve timing of control actions. Findings will be used to guide more targeted prevention and early-warning efforts in at-risk cities.

Who could benefit from this research

Good fit: People who live in malaria-prone cities—especially in South Asia where Anopheles stephensi is common or in African cities at risk of invasion—are the groups this work aims to help and whose local data would be most useful.

Not a fit: People living in rural areas or regions without urban-adapted malaria transmission (or areas not affected by Anopheles stephensi) are less likely to see direct benefits from this urban-focused research.

Why it matters

Potential benefit: If successful, this work could help public health officials predict and prevent urban malaria outbreaks, reducing infections for people who live in affected cities.

How similar studies have performed: Previous studies have shown strong links between temperature and malaria risk, but coupling temperature and humidity for urban malaria—particularly for Anopheles stephensi—is relatively novel and less well tested.
