The Nigeria Centers for Disease Control has reported an ongoing outbreak of yellow fever beginning in September 2017.

By the end of November 2018: Fourteen states had reported more than 55 laboratory-confirmed cases of yellow fever; all 36 states and the Federal Capital Territory had reported more than 3,500 suspected cases and a number of deaths and Edo State had reported a large number of suspected cases, several of them laboratory-confirmed as yellow fever.

Travelers going to Nigeria should receive vaccination against yellow fever at least 10 days before travel and should take steps to prevent mosquito bites while there.

Those never vaccinated against yellow fever should avoid travel to Nigeria during the outbreak.

Yellow fever is caused by a virus. The virus is spread to people by mosquito bites. Symptoms of yellow fever include fever, chills, headache, backache, and muscle aches. Symptoms take 3–6 days to develop after infection. About 15% of people who get yellow fever develop serious illness including bleeding, shock, organ failure, and sometimes death.
