Cholera Prevention: 7 Essential Precautions for Travelers & Communities

Cholera is preventable with consistent barriers. These 7 precautions cover the critical control points:

1. Hand hygiene: Soap + water after toilet, before eating/cooking, after patient care. Alcohol gel if no water (less effective on soiled hands).
2. Safe water: Boil 1 min (3 min >2000m), or chlorine tablets (follow contact time), or certified filter (0.1–0.2 μm), or bottled (sealed).
3. Food safety: Cook thoroughly (≥70°C core). Peel fruits/veggies yourself. Avoid raw seafood, salads, street ice.
4. Sanitation: Use improved latrine/toilet. Dispose of child feces safely. No open defecation near water sources.
5. Avoid contact with sick: Designated caregiver, gloves, bleach disinfection (0.2% for surfaces, 0.05% for laundry).
6. Vaccination: OCV (Shanchol/Euvichol) ≥1 week before travel to endemic area. 2-dose series; single dose if imminent exposure.
7. Early care seeking: Watery diarrhea → start ORS immediately. Continue feeding. Red flags (lethargy, sunken eyes, no urine >6h) → clinic.
