Yellow fever is a disease transmitted by infected mosquitoes that bite during the day. The most common symptoms are fever, muscle pain with prominent obvious backache, headache, loss of appetite, and feeling or being sick (nausea or vomiting). A small proportion of people that become infected can become severely unwell and die.

Advice to travellers

If you are visiting an area where yellow fever is present you should:

• use personal protective measures to avoid mosquito bites at all times

A yellow fever vaccine is available to protect you against yellow fever. Vaccination is recommended if you are visiting areas where there is a risk of yellow fever transmission. The vaccine is only available at designated yellow fever centres.

South Sudan requires a yellow fever vaccination certificate for all travellers aged 9 months and older.
