Cholera risk in Luanda

Cholera Risk Prevention Guide for Luanda

Risk Score: 67/100

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

Luanda faces several specific challenges. The city's rapid urban growth has outpaced water and sanitation infrastructure. Many residents rely on informal water vendors and shallow wells that are easily contaminated during rains. Overcrowded neighborhoods with limited sewage systems, combined with tropical flooding, create ideal conditions for outbreaks. Street food vendors often use untreated water for preparation. Bairro-level markets sell produce washed in river water, and household water storage containers are frequently uncovered and contaminated.

Prevention steps:

1. Treat all drinking water. Boil for at least one minute or use chlorine tablets. Store water in clean, covered containers and use a tap or pour method to avoid dipping hands inside.

2. Practice strict handwashing with soap after using the toilet and before handling food. If soap is unavailable, use ash and water as an alternative.

3. Eat food that is thoroughly cooked and served hot. Avoid raw vegetables, unpeeled fruits, and street food unless you can confirm safe water was used in preparation.

4. Dispose of human waste properly. Use latrines and keep them away from water sources. If flooding occurs, do not allow children to play in standing water near waste areas.

5. Report suspected cases immediately to local health authorities. Early rehydration with oral rehydration salts saves lives. Keep a supply at home.

Seek medical care urgently if you develop watery diarrhea or vomiting.
