Cholera risk in Ouagadougou

Cholera is an acute diarrheal illness caused by the bacterium Vibrio cholerae, spread primarily through contaminated water and food. It can kill within hours if untreated, but it is both preventable and treatable.

In Ouagadougou, several factors keep the risk score at 59 out of 100. Seasonal flooding during the rainy season spreads sewage into drinking water sources. Overcrowded neighborhoods like Tanghin, Kilwin, and parts of Pissy face unreliable tap water supply, forcing residents to rely on untreated wells and vendors. Street food vendors often wash hands and utensils in contaminated water, and open defecation persists in areas lacking proper sanitation infrastructure. The warm climate allows the bacteria to thrive year-round.

Five actionable prevention steps for residents of Ouagadougou:

1. Treat your water before drinking. Boil water for at least one full minute or use chlorine-based purification tablets. Store treated water in clean, covered containers with narrow openings to prevent recontamination.

2. Avoid untreated street food during the rainy season. If eating out, choose freshly cooked, hot foods. Peel all fruits and vegetables yourself rather than eating pre-cut produce from vendors.

3. Wash hands with soap at critical moments: before eating, after using latrines, and after handling children. Where soap is scarce, use ash and clean water as an alternative.

4. Support household latrine maintenance. Ensure your family latrine is at least 30 meters from any water source. Report broken latrines to community health workers for prompt repair.

5. Recognize symptoms early and act fast. Watery diarrhea with vomiting requires immediate oral rehydration salts. Visit the nearest health center within hours, not days. Do not wait for confirmation.

Community health workers in Ouagadougou distribute oral cholera vaccines during outbreaks. Ask at your nearest CSPS about availability. Prevention starts with household habits.
