Public health authorities in South Sudan reported an outbreak of yellow fever in Yambio County, West Equatoria State on 24 December 2024.
Yellow fever is an acute viral haemorrhagic disease which is transmitted through the bite of an infected mosquito. It is found in tropical areas of Africa and Central and South America.
All travellers should be advised to practice mosquito bite avoidance at all times.
A traveller's risk of yellow fever is determined by their individual risk assessment. Factors that will influence their risk includes:
country or countries to be visited
length of stay
rate of transmission at destination
Unvaccinated travellers who visit yellow fever endemic areas are at risk of becoming infected.
Yellow fever vaccine should be considered (unless contraindicated) for travellers at risk.
South Sudan requires a yellow fever vaccination certificate for all travellers aged 9 months and older.
