Papua New Guinea
Status: no longer infected but vulnerable to re-infection
International Health Regulations
Papua New Guinea is classified by the International Health Regulations (IHR) as a state no longer infected, but which remains vulnerable to re-infection. It is therefore subject to temporary recommendations as of June 2020.
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.
