UN warns El Nino to worsen malnutrition, cholera, vector-borne disease globally

WHO and other UN agencies warn that a rapidly strengthening El Nino will intensify health crises worldwide, including malnutrition, cholera, and mosquito-borne diseases, as food insecurity rises. The claim is based on UN agency projections, with uncertainty over the magnitude and regional distribution of impacts. This matters because it signals a looming public-health emergency that could strain health systems and drive humanitarian needs.
