Yellow fever is an acute viral haemorrhagic disease.
As of 2023, 34 countries in Africa and 13 countries in Central and South America are endemic for yellow fever.
Yellow fever is prevented by an extremely effective vaccine, which is safe and affordable. A single dose of yellow fever vaccine is sufficient to grant sustained immunity and life-long protection against yellow fever disease.
Yellow fever is transmitted by infected mosquitoes.
Symptoms of yellow fever include hemorrhagic fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue.
A small proportion of patients who contract the virus develop severe symptoms and approximately half of those die within 7 to 10 days.
30% to 60% of infected persons who develop severe disease die.
Yellow fever virus is estimated to cause 200,000 cases of disease and 30,000 deaths each year, with 90% occurring in Africa.
