International Health Regulations

Nigeria is classified by the International Health Regulations (IHR) as a state infected with cVDPV2 with potential risk of international spread.  It is therefore subject to temporary recommendations as of May 2021.

Travel advice

WHO’s International Travel and Health recommends that all travellers to polio-affected areas be fully vaccinated against polio. Residents (and visitors for more than 4 weeks) from infected areas should receive an additional dose of OPV or inactivated polio vaccine (IPV) within 4 weeks to 12 months of travel.
