Cholera
What is Cholera?
Cholera is a serious bacterial infection that causes severe diarrhoea and dehydration. It’s linked to unsafe drinking water and poor sanitation.
How is Cholera Spread?
It spreads through contaminated food or water, especially in areas with poor hygiene and sanitation.
Who is at Risk?
- Travellers to high-risk countries (Africa, Asia, Central/South America)
- People staying in rural or remote areas
- Aid workers, volunteers, and healthcare staff in outbreak regions
- Individuals with limited access to clean water
Signs and Symptoms:
- Sudden, watery diarrhoea
- Nausea and vomiting
- Rapid dehydration
- Muscle cramps, weakness, and low blood pressure
When to Consider Vaccination:
- If you’re travelling to a region with a known outbreak
- If you’ll be working in areas with poor sanitation or limited healthcare
- If you’re at increased risk due to medical conditions
The Vaccine:
The oral vaccine is taken in 2-3 doses, depending on age. It protects against cholera for up to two years and is best used alongside good hygiene and food/water safety.
Do
- Drink bottled, boiled, or purified water in areas with poor sanitation
- Wash hands thoroughly with soap, especially before eating and after using the toilet
- Take the full course of the oral cholera vaccine if advised for your destination
Do not
- Drink untreated water from taps, wells, or rivers
- Rely solely on alcohol hand gels in high-risk areas
- Skip vaccination if travelling to areas with recent cholera outbreaks
