International Health Regulations
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. It is therefore subject to temporary recommendations as of May 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.
