About Yellow fever:

  • Yellow fever is often associated with jaundice, hence the name yellow.
  • Yellow fever occurs in 47 endemic countries in Africa and in Central and South America.
    • Around 90% of cases reported every year occur in Sub-Saharan Africa.
  • The yellow fever virus is transmitted by infected mosquitoes, most commonly from the Aedes species – the same mosquito that spreads the Zika, Chikungunya and Dengue virus.
    • Haemogogus mosquitoes also spread it and are mostly found in the jungle.
    • The disease cannot spread by contact from one person to another.
  • Symptoms: 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.
  • Prevention and Treatment:
    • A single dose of yellow fever vaccine, known as 17D, provides life-long immunity against the disease.
    • There is no specific treatment for yellow fever but good supportive treatment of symptoms, such as dehydration, fever and infection, improves survival rates.
