International Health Regulations
Democratic Republic of the Congo is classified by the International Health Regulations (IHR) as a state infected with circulating vaccine-derived poliovirus type 1 (cVDPV1) with potential risk of international spread and cVDPV2, with or without evidence of local transmission. It is therefore subject to temporary recommendations as of August 2023.
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.
