Yellow Fever
What is Yellow Fever?
Yellow fever is a viral infection spread by mosquitoes in parts of Africa and Central/South America. Severe cases can cause jaundice, organ failure, and death.
How is it Spread?
- Through the bite of an infected mosquito
- Mosquitoes bite mainly during the daytime
- Not spread person to person
Who is at Risk?
- Travellers to endemic regions
- People spending time in jungles, rural, or urban areas where yellow fever is present
- Those involved in outdoor activities (trekking, camping)
- Travellers to countries that require proof of vaccination
Signs and Symptoms:
- Fever, headache, muscle aches
- Nausea, vomiting, tiredness
- In severe cases: jaundice, abdominal pain, bleeding, and organ failure
When to Consider Vaccination:
- Before travel to yellow fever risk areas
- When a country requires an International Certificate of Vaccination
- If staying for long periods or exposed to mosquitoes in endemic regions
The Vaccine:
- Single yellow fever vaccine injection
- Provides lifelong protection for most people
- Certificate valid for life
- Not suitable for everyone (e.g., certain medical conditions, babies under 6 months)
- Safe and well tolerated, with mild side effects in some cases
Do
- Get vaccinated at least 10 days before travel to affected countries — and carry your certificate
- Protect yourself against mosquito bites using repellent, clothing, and nets
- Check entry requirements for countries even if just transiting through a Yellow Fever zone
Do not
- Forget your International Certificate of Vaccination — it’s required for entry in some countries
- Assume the vaccine alone is enough — mosquito protection is still essential
- Travel without confirming whether the vaccine is legally required
