Cholera Prevention

Cholera is a severe bacterial infection caused by Vibrio cholerae. It’s primarily spread through contaminated food or water and is most prevalent in areas with inadequate sanitation and limited access to clean water. Cholera can cause acute diarrhoea and dehydration, which can be life-threatening if not treated promptly.

Why You May Need the Cholera Vaccine

Travellers visiting regions with poor sanitation or limited access to safe drinking water may be at increased risk of contracting cholera. The cholera vaccine provides vital protection, reducing the risk of severe illness and allowing you to travel with peace of mind.

Destinations at Risk

Cholera remains a concern in various parts of the world, particularly in:

• Parts of Africa
• South and Southeast Asia
• Haiti and the Caribbean
• Countries experiencing natural disasters or humanitarian crises

If your travel plans include these regions, it’s crucial to consult with a travel health professional about the cholera vaccine.

The Cholera Vaccine: What You Need to Know

The cholera vaccine is an oral vaccine designed to protect against Vibrio cholerae. It works by stimulating the immune system to produce antibodies that fight the bacteria.

How Many Doses Do I Need?

The cholera vaccine typically requires two oral doses taken at least one week apart for adults and children aged 6 years and older. For children aged 2-5, three doses are recommended, each spaced at least one week apart.

How Long Does It Take to Work?

Full protection begins about one week after completing the final dose. It’s essential to complete the course at least one week before travelling to a high-risk area.

How Long Does the Vaccine Last?

The vaccine provides protection for around 2 years in adults and 6 months in children aged 2-5. A booster dose is recommended if you continue to be at risk after this period.

Is the Cholera Vaccine Safe?

The oral cholera vaccine is generally safe and well-tolerated. Common side effects include mild gastrointestinal discomfort, nausea, or abdominal cramps. If you have specific medical conditions or allergies, please discuss these with our pharmacists before receiving the vaccine.

Can Children Have the Cholera Vaccine?

Yes, the vaccine is approved for children aged 2 and above. The dosage and schedule may vary depending on the child’s age.

Additional Tips for Cholera Prevention

In addition to vaccination, it’s essential to practice good hygiene and food safety while travelling in areas at risk of cholera. Here are some key precautions:

• Drink only bottled or boiled water and avoid ice cubes unless made with safe water.
• Eat food that has been thoroughly cooked and is served hot.
• Avoid raw fruits and vegetables unless you can peel them yourself.
• Practice regular handwashing with soap and clean water, especially before eating and after using the toilet.

Signs and Symptoms of Cholera

Cholera symptoms can appear within hours to a few days after infection. They include:

• Profuse watery diarrhoea
• Vomiting
• Muscle cramps and leg cramps
• Severe dehydration, which can lead to shock and be life-threatening

If you or a family member develop these symptoms while travelling or shortly after returning home, seek medical attention immediately.
