Researchers say climate patterns can affect when and where infectious, parasitic diseases emerge by altering the survival and behavior of disease-carrying vectors and animal hosts. They note that weather information can sometimes help forecast some disease risks days or weeks ahead, but predicting how those risks shift across seasons and years is still challenging.
In interviews discussing their recent work, researchers Adrià San José Plana, who models infectious diseases, and Xavier Rodó, a research professor and founding director of the Catalan Institute of Climate Sciences in Barcelona, describe efforts to connect environmental signals—such as ocean conditions and desert rainfall—with disease dynamics. The reporting across outlets centers on how climate variability may create conditions that influence transmission, and on the limitations of current forecasting methods over longer time horizons.
Overall, the articles highlight emerging research that aims to improve understanding of climate–disease linkages, while emphasizing that translating these patterns into reliable long-term risk forecasts remains difficult.
