International Health Regulations

Nigeria is classified by the International Health Regulations (IHR) as a state infected with cVDPV2, with or without evidence of local transmission.  It is therefore subject to Temporary Recommendations issued by the International Health Regulations Emergency Committee on Polio Eradication (issued as of August 2023).

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.
