Nigeria (Security threat level - 5):
On 3 December 2018, the U.S. Embassy in Abuja issued a Health Alert, which reads in part as follows:
"Event: On October 28, The Center for Disease Control (CDC) in the United States issued a Travel Notice
for polio in Nigeria. The Nigerian Ministry of Health has reported several cases of poliovirus in the northern states of Nigeria. CDC recommends that all travelers to Nigeria be vaccinated fully against polio. Because of the risk of cross-border transmission of the Lake Chad region, CDC recommends a one-time booster dose of polio vaccine for fully vaccinated adults traveling to Nigeria, Niger, Cameroon, or Chad to work in healthcare facilities, refugee camps, or other humanitarian aid settings. In addition, Nigerian immigration officials may request proof of polio vaccination for travelers entering or exiting Nigeria.
"Actions to Take:
- Visit CDC’s website on polio.
- Take necessary precautions described on the CDC’s website to avoid infection and get vaccinated for polio or acquire a booster.
- Carry records of polio vaccination when entering or exiting Nigeria.
- If exposed, seek immediate medical care OR contact a doctor right away.
- Monitor local media and NCDC website for updates.
- Visit the CDCTravelers Health Page.
