What is the most effective measure to prevent diarrheal diseases in detainee camps?

• A. Provision of safe water in sufficient quantity
• B. Building of latrines
• C. Distribution of soap
• D. Appropriate site planning to avoid overcrowding

Answer: (A)

Access to safe, sufficient water is the most effective measure to prevent diarrheal diseases in detainee camps. Diarrhoea spreads mainly through ingestion of contaminated water and through poor hygiene; when clean water is readily available in adequate quantities, people can drink enough to stay hydrated and perform essential hygiene practices such as handwashing and cleaning utensils, which interrupts the fecal-oral transmission route.

Other measures matter, but their impact hinges on having reliable safe water. Latrines reduce environmental contamination, yet if water is unsafe or scarce, people may still consume contaminated water or struggle with proper hygiene. Soap supports handwashing, but without enough water, its effectiveness is limited. Thoughtful site planning to avoid overcrowding reduces transmission risk, but it doesn’t directly ensure water safety or hygiene practices.
