Cholera risk in Douala

Cholera Prevention Guide for Douala Risk Score: 66/100 Cholera is an acute diarrheal illness caused by the bacterium Vibrio cholerae, usually spread through contaminated water and food. Without treatment, severe dehydration can lead to death within hours. In Douala, your risk is elevated due to several local factors: the city's dense population, frequent flooding during rainy seasons, limited access to safe municipal water in many neighborhoods, overcrowded informal settlements near the Wouri River estuary, heavy reliance on street-vended food and water, and inadequate sewage infrastructure in large parts of the city. These conditions allow cholera to spread quickly, especially between May and November when rains intensify. Here are practical steps to protect yourself: 1. Treat all drinking water. Boil water for at least one full minute, or use chlorine tablets or certified filters. Never drink from public taps, wells, or river water without treatment. Store water in clean, covered containers. 2. Eat only thoroughly cooked, hot food. Avoid raw vegetables washed in tap water, unpeeled fruits, and street food sitting uncovered. Peel fruits yourself and discard the skin. 3. Wash hands with soap and clean water before eating, after using the toilet, and after handling money or surfaces in public areas. Carry hand sanitizer as backup. 4. Avoid swimming or wading in the Wouri River, drainage canals, or standing floodwater, especially after heavy rains. These are common contamination sources. 5. If you develop sudden watery diarrhea, begin oral rehydration immediately using a solution of clean water, sugar, and salt, and seek medical care at a nearby health facility without delay. Early rehydration saves lives.
