Cholera risk in Lagos

CHOLERA RISK IN LAGOS Risk Score: 68/100 What is cholera? Cholera is an acute diarrheal illness caused by the bacterium Vibrio cholerae. It spreads through contaminated water and food and can cause severe dehydration and death within hours if untreated. Symptoms include profuse watery diarrhea, vomiting, and leg cramps. Lagos-specific risk factors Lagos faces elevated cholera risk due to several local conditions. Overcrowded areas like Mushin, Ajegunle, and Makoko experience frequent outbreaks because of limited clean water access and poor sanitation infrastructure. The rainy season, typically April through October, increases flooding that contaminates water sources. Open defecation remains common in informal settlements. Many residents rely on sachet water and boreholes that can become contaminated. Street food vendors often use unsafe water for preparation. The Alaba and Oshodi markets see high transmission due to dense vendor populations and limited handwashing facilities. Prevention steps 1. Treat your water always. Boil water for at least two minutes before drinking or use approved water treatment tablets. Avoid ice made from unknown sources. 2. Wash hands with soap and clean water after using the toilet and before eating. If soap is unavailable, use ash as a substitute, common in many Lagos households. 3. Eat food that is thoroughly cooked and served hot. Avoid raw vegetables and fruits you cannot peel yourself. Street food carries higher risk, so choose vendors who use clean water and practice visible hygiene. 4. Dispose of feces safely. Use designated latrines and keep children from playing near open sewage channels common in flood-prone areas. 5. Report cases immediately to the nearest primary health center. Early treatment with oral rehydration salts prevents severe outcomes. Contact the Lagos State Ministry of Health hotline at 08023169485. If you experience watery diarrhea, begin oral rehydration immediately while seeking medical care.
