Cholera risk in Cotonou

Cholera Prevention Guide for Cotonou, Benin

Risk Score: 66/100 - Moderate to High

Cholera is a bacterial infection spread through contaminated water and food that causes severe diarrhea and dehydration. Cotonou faces elevated risk due to seasonal flooding, crowded neighborhoods like Dantokpa market area, limited sanitation infrastructure, and frequent reliance on untreated well water and lagoon water sources. The humid climate and warm temperatures allow bacteria to thrive year-round, with cases typically increasing during the rainy season from April through October.

Protection Steps

1. Drink only treated water. Boil all water for at least one full minute or use chlorine purification tablets. Avoid ice from street vendors since it may be made from untreated water. Bottled water with sealed caps is safest.

2. Wash hands with soap and clean water before eating and after using any toilet. If soap is unavailable, use ash and water. This single step dramatically reduces transmission risk.

3. Eat food thoroughly cooked and served hot. Avoid raw vegetables, shellfish from the lagoon, and food left standing at room temperature. Peel fruits yourself.

4. Use proper sanitation. Do not defecate near water sources. Use latrines or designated facilities, especially in areas around Akpakpa and Saint Rita where open defecation remains common.

5. Seek treatment immediately if you develop watery diarrhea. Oral rehydration salts are critical. Clinique de Porto-Novo and CNHU in Cotonou have cholera treatment centers. Early treatment prevents severe dehydration and death.
