Cholera risk in Fortaleza

Cholera is a bacterial infection caused by Vibrio cholerae, spread through contaminated water and food. It triggers severe diarrhea and dehydration and can become fatal without prompt treatment. Fortaleza's risk score of 59/100 reflects moderate-to-elevated danger, especially during rainy season (January–June), when flooding overwhelms sewage systems and contaminates water sources.

Local risk factors in Fortaleza include: intermittent water supply leading to unsafe storage, overcrowded neighborhoods with poor sanitation infrastructure, street food vendors using untreated water, and widespread informal settlements near contaminated waterways.

Prevention steps:

1. Treat all drinking water. Boil for one minute or use chlorine tablets or certified filters. Avoid tap water, even if it looks clear, and never drink from street vendors offering untreated options.

2. Practice strict hand hygiene. Wash hands with soap and clean water after using the bathroom, before eating, and before food preparation. If soap is unavailable, use alcohol-based sanitizer.

3. Eat only thoroughly cooked food. Avoid raw vegetables, unpeeled fruits, and seafood from unregulated vendors. Choose busy food stalls where turnover is high and food is freshly prepared and served hot.

4. Store water safely. Use containers with narrow openings and lids. Avoid dipping hands or cups directly into stored water; pour instead.

5. Know dehydration signs and act fast. If you develop sudden watery diarrhea, begin oral rehydration immediately using WHO-available packets or a homemade solution: six teaspoons sugar, half teaspoon salt, one liter clean water. Seek medical care promptly—cholera is treatable with antibiotics and rehydration therapy.
