Researchers at the Indian Institute of Technology (IIT) Kharagpur have developed CliMed, a climate-informed and spatially explicit modelling framework for dengue risk assessment over India. The model brings together daily climate information, land-use characteristics, human population data, settlement context and mosquito-species suitability to generate interpretable risk signals for Aedes-borne dengue transmission.

Dengue risk is shaped by several interacting conditions. Temperature influences mosquito biting, development, survival and the time required for the virus to become transmissible inside the mosquito. Rainfall can create breeding opportunities, while very heavy rainfall may also disturb...
