Cholera risk in Pointe-Noire

Cholera is an acute diarrheal illness caused by the bacterium Vibrio cholerae. It spreads through contaminated food and water and can cause severe dehydration and death if untreated.

Pointe-Noire faces a cholera risk score of 67/100 due to overcrowded neighborhoods, inconsistent water supply, open drainage systems, limited sewage infrastructure, and reliance on untreated well or river water in some areas. Markets and street food vendors may also pose contamination risks, especially during rainy seasons when flooding spreads waste into water sources.

Five practical prevention steps:

1. Treat all drinking water. Boil water for at least one full minute, or use chlorine tablets or certified water filters. Avoid ice from unknown sources and drink only sealed bottled water when treatment is unavailable.

2. Wash hands thoroughly with soap and clean water before eating, after using the toilet, and after handling waste. If soap is not available, use ash or hand sanitizer with at least 60% alcohol.

3. Cook food thoroughly and eat it while hot. Avoid raw seafood from local waters, unpeeled fruits, and street food left exposed to flies or dust. Peel fruits yourself with clean hands.

4. Use latrines or designated toilets. Never defecate in open areas, drainage channels, or near water sources. Ensure children's waste is disposed of safely.

5. Act immediately at the first sign of watery diarrhea. Begin oral rehydration with a solution of clean water, salt, and sugar. Seek medical care at the nearest health center without delay, as early treatment saves lives.
