Yellow Fever is a serious viral infection spread through mosquito bites in parts of Africa and South America. In severe cases it can cause liver damage, internal bleeding and organ failure.

Yellow Fever is spread through bites from infected mosquitoes, mainly in tropical and subtropical regions where the virus is present.

Symptoms can include fever, headaches, muscle pain, nausea and tiredness. Severe infections may lead to jaundice, bleeding and serious organ complications.

Some countries in Africa and South America require proof of Yellow Fever vaccination for entry. Requirements can vary depending on your destination and travel route.

For most travellers, a single Yellow Fever vaccination provides lifelong protection and an official certificate valid for international travel.

Vaccination is the most effective protection against Yellow Fever. Travellers should also avoid mosquito bites by using insect repellent, mosquito nets and protective clothing.
