## El Niño health risks
El Niño shifts global weather patterns, causing heat waves, floods and droughts that threaten health.
## Southern Africa drought risks
Southern Africa faces rising drought risks that could affect the 2026-27 growing season in key farming regions.
## Horn of Africa flooding risks
Wetter-than-normal conditions in the Horn of Africa raise risks of flooding and mosquito-borne disease outbreaks.
## Southeast Asia wildfires
Dry conditions in Southeast Asia fuel wildfires and reduce water supplies.
## Chilean floods
October 2026 storms in Chile triggered mudslides that left homes and yards difficult to clean.
## US weather patterns
The US South gets wetter during El Niño, while the Northern Plains face higher drought risks.
## Health impacts of floods
Floodwater carries infections like hepatitis, cryptosporidium and fungal diseases.
## Drought health effects
Drought causes poor air quality and malnutrition in some areas.
## Vulnerable populations
At least 2.5 million Americans rely on home medical equipment that could fail during power outages.
## Rural access challenges
Rural Americans live 10.5 miles from hospitals, with many taking over 30 minutes to reach care.
## Early warnings save lives
Communities with early warnings can prepare medical equipment and help vulnerable people during disasters.
## Key takeaway

El Niño weather patterns increase health risks like floods and droughts, but early warnings with specific actions can save lives.
