Drought can fuel some infectious diseases, new research shows
A new review of nearly 100 studies reveals that drought can paradoxically increase the spread of certain infectious diseases like cholera, West Nile virus, and dengue, even though water-borne pathogens might be expected to decline. The phenomenon, termed the 'drought-disease paradox,' occurs because reduced water can concentrate pathogens or alter animal behavior. Researchers are studying how drier conditions shape disease transmission across ecosystems.
