Cholera risk in Bandung

Cholera Prevention Guide for Bandung Residents Cholera is a bacterial infection caused by Vibrio cholerae that leads to severe watery diarrhea, vomiting, and rapid dehydration. Without prompt treatment, it can become fatal within hours. Bandung carries a moderate-to-high cholera risk score of 67/100 due to several local factors. The city experiences frequent flooding during the rainy season, which contaminates water sources with sewage. Dense urban neighborhoods often have limited access to clean piped water, and street food culture is widespread. Open drainage systems and occasional sanitation infrastructure failures create conditions where the bacteria spread easily through contaminated water and food. Here are five actionable steps you can take to protect yourself and your family. Always treat your drinking water. Boil water for at least one minute or use chlorine purification tablets before drinking. In areas with unreliable tap water, avoid drinking directly from the source. Wash your hands thoroughly with soap and clean water before eating and after using the toilet. Handwashing is the single most effective way to prevent cholera transmission. Eat thoroughly cooked food. Avoid raw or undercooked seafood, and be cautious with street food, especially dishes that may have been sitting at room temperature for long periods. Peel fruits yourself before eating. Keep your living environment clean. Ensure waste is disposed of properly and drains around your home are kept clear, especially during the rainy season when flooding spreads contamination. Know the warning signs and act fast. If you experience sudden onset of watery diarrhea, seek medical attention immediately. Oral rehydration salts can be life-saving while you get to a health facility. Bandung's community health centers (puskesmas) provide free or low-cost treatment. Vaccination is also available for high-risk groups. Ask your local puskesmas about the oral cholera vaccine.
