Cholera
9 Épidémie ActivesCholera is an acute diarrheal disease caused by contaminated water or food. It can kill within hours if untreated but is easily treatable with immediate rehydration. While rare in developed countries, cholera remains a major threat in areas with poor sanitation.
Qu'est-ce que Cholera?
Cholera has caused seven pandemics since 1817, with the current pandemic beginning in 1961. The disease causes profuse watery diarrhea ('rice-water stool') and vomiting, leading to severe dehydration and death within hours if untreated. An estimated 2.9 million cases and 95,000 deaths occur annually worldwide. Simple oral rehydration solution (ORS) has a 99%+ success rate, making cholera one of the most preventable deaths.
SymptĂ´mes
- Profuse watery diarrhea ('rice-water stool')
- Vomiting
- Rapid dehydration symptoms: extreme thirst, dry mucous membranes, sunken eyes
- Muscle cramps (from electrolyte loss)
- Low blood pressure and rapid heart rate
- Shock and organ failure (if untreated)
- Most cases are mild; 10-20% develop severe disease
Transmission
Fecal-oral route through contaminated water or food. Common sources: untreated water, raw/undercooked shellfish, produce washed with contaminated water. Person-to-person spread uncommon.
Période de Contagiosité : While bacteria are in stool (typically 7-14 days after recovery); requires contaminated water/food to spread
Prévention
- Drink only safe water (boiled, bottled, or treated with chlorine/iodine)
- Eat only thoroughly cooked food served hot
- Avoid raw/undercooked seafood and shellfish
- Peel fruits and vegetables yourself
- Wash hands with soap and safe water before eating and after bathroom
- Oral cholera vaccine for high-risk travel or outbreak response
- Proper sanitation and sewage treatment (community-level)
- WASH programs (Water, Sanitation, Hygiene) in at-risk areas
- Avoid ice unless made from safe water

Cholera Outbreak Hits Burundi Linked to Sanitation Issues
Burundi has been experiencing a protracted cholera epidemic since late 2022, with thousands of cases reported nationally through 2025, concentrated in northwestern districts and urban areas such as Bujumbura and Nyanza-Lac. Recurrent surges are driven by limited access to safe water and sanitation, and the influx of displaced populations continues to strain local health services, requiring ongoing support from national authorities and partners such as MSF and UNICEF.
