Hygiene practices prevent fecal-oral transmission diseases

Steps:

• Analyze advice: Focuses on food safety (cooking, peeling) and handwashing with boiled water to avoid contamination.
• Identify transmission: Targets ingestion of pathogens from unclean water/food, indicating fecal-oral route.
• Match to options: Cholera spreads via contaminated water/food; others use different routes.
• Confirm: Advice aligns with WHO guidelines for cholera prevention.

Why A is correct:

• Cholera, caused by Vibrio cholerae, transmits through fecal-oral route in contaminated food/water, directly prevented by boiling water, cooking food, and hand hygiene.

Why the others are wrong:

• B: Malaria spreads via Anopheles mosquito bites, not food/water.
• C: Measles transmits through respiratory droplets/airborne, unaffected by food hygiene.
• D: Tuberculosis spreads via airborne droplets from coughs, not ingestion.

Final answer: A
