## El Niño's Global Impact

El Niño, a natural climate phenomenon, disrupts global weather patterns, causing heatwaves, floods, and droughts. These events pose significant health risks, from waterborne diseases to malnutrition. Communities worldwide must prepare for these challenges by integrating health warnings into weather forecasts.

## Health Risks in Africa

Southern Africa faces severe drought risks during El Niño, threatening the 2026-27 growing season. Conversely, the Horn of Africa experiences increased rainfall, raising the risk of flooding and mosquito-borne diseases. These conditions highlight the diverse health threats El Niño brings to different regions.

## Southeast Asia and Chile

In Southeast Asia, dry conditions fuel wildfires and deplete water supplies. Meanwhile, Chile experienced heavy October rains, leading to mudslides that disrupted homes and communities. These events underscore the varied and severe impacts of El Niño on local health and infrastructure.

## US Weather Patterns

In the US, El Niño typically brings wetter conditions to the South, drought to the Northern Plains, and fierce storms along the Pacific Coast. These weather shifts can lead to health emergencies, emphasizing the need for comprehensive preparedness plans.

## Long-term Health Effects

Extreme weather events linked to El Niño can cause long-term health issues, including psychological distress and chronic stress. Floodwaters may carry infections like hepatitis and cryptosporidium, while droughts can lead to poor air quality and malnutrition.

## Vulnerable Populations

Individuals with existing illnesses or those living far from medical care face heightened risks during El Niño. Early warnings can help these populations prepare, ensuring access to essential healthcare and reducing the impact of extreme weather on their health.

## Community Preparedness

Effective weather warnings provide actionable information, helping residents stay safe during disasters. Communities can prepare by identifying high-risk areas, ensuring continuity of clinical care, and educating the public about storm risks and available resources.

## Preventive Measures

Preparation is key to mitigating El Niño's health impacts. By integrating health risks into early warnings and providing practical actions, communities can empower residents to face disasters with confidence and reduce the overall health burden.
