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.
Yellow fever is the only disease specified in the International Health Regulations (2005) (IHR (2005)) for which countries may require proof of vaccination from travellers as a condition of entry under certain circumstances. A list of countries with risk of yellow fever transmission and countries requiring yellow fever vaccination can be found on WHO website at http://www.who.int/ith/2017-ith-annex1.pdf?ua=1.
Following the amendment to the IHR (2005) on 11 July 2016, currently valid certificates continue to be valid for the life of the traveller indicated. Existing certificates do not need to be changed or modified to show they are valid for life.
