Which option is not an appropriate preventive measure listed for diarrheal diseases?

• A. Provision of safe water in sufficient quantity
• B. Building of latrines
• C. Distribution of soap
• D. Do whatever is necessary to make yourself the SME

Answer: (D)

Preventing diarrheal diseases hinges on interrupting transmission through water, sanitation, and hygiene (WASH). Providing safe water in adequate quantities reduces the ingestion of pathogens. Building latrines lowers fecal contamination in the environment and decreases exposure to fecal matter. Distribution of soap enables effective handwashing, cutting the spread of pathogens via hands.

The option about doing whatever is necessary to make yourself the SME does not translate into a public health action and would not reduce transmission. It lacks a concrete, evidence-based preventive mechanism and isn’t something that would prevent diarrheal disease in a community.

So, focus on measures that directly reduce exposure to fecal-oral pathogens: safe water, proper sanitation, and good hygiene practices.
