El Niño: Public Health Situation Analysis.

This Public Health Situation Analysis (PHSA), covering July-September 2023, identifies the current and potential health impacts that vulnerable populations may face as a result of the global El Niño climate event, and describes health systems’ capacities to respond.The ongoing El Niño is highly likely to have wide-ranging health implications on a global scale. In the coming months, the most severe health threats are likely to arise from malnutrition due to ongoing food insecurity compounded by the effects of El Niño, heat stress, environmental pollution, cholera, and other diarrhoeal diseases.Detailed information on key health threats and at-risk countries is presented throughout the document. WHO acts as part of a UN-wide coordination and monitoring mechanism for El Niño, and supports countries through programmatic work to address key health threats, and via direct support to countries.
