What is yellow fever?
Yellow fever is an acute infection caused by the yellow fever virus. The virus is transmitted via the bite of infected mosquitoes. The disease is endemic in tropical areas of Africa and Latin America. The incubation period is about 3 to 6 days. Some people may develop sudden onset of fever, chills, headache, back pain, generalised muscle pain, weakness, fatigue, nausea and vomiting. About 15% of the symptomatic cases will progress to a more severe form of the disease. The severe form is characterised by high fever, jaundice, bleeding, and eventually shock and failure of multiple organs.
Vaccination against yellow fever is available. Travellers who are vaccinated against yellow fever will be given an International Certificate of Vaccination or Prophylaxis. Travellers should remember that the certificate is valid only 10 days after the primary injection. The first dose of vaccine takes 10 days to provide good protection, hence adequate time should be allowed for vaccination before departure.
Who needs yellow fever vaccination?
The World Health Organization (WHO) recommends immunisation for all travellers aged 9 months and above, travelling to and from at-risk areas, unless they are contraindicated for vaccination.
Some countries require proof of yellow fever vaccination as a condition of entry or transit for travellers arriving from certain countries. A list of countries with risk of yellow fever transmission and countries requiring yellow fever vaccination can be found on WHO website at www.who.int.
