Iran (Islamic Republic of)

Status: no longer affected by circulating vaccine-derived poliovirus 2 (cVDPV2) but remains vulnerable to re-infection

WHO advice

It is important that all countries, in particular those with frequent travel and contacts with polio-affected countries and areas, strengthen surveillance for AFP cases in order to rapidly detect any new virus importation and to facilitate a rapid response. Countries, territories and areas should also maintain uniformly high routine immunization coverage at the district level to minimize the consequences of any new virus introduction.

International Health Regulations

Iran (Islamic Republic of) is classified by the International Health Regulations (IHR) as a state no longer infected by cVDPV, but which remains vulnerable to re-infection.  It is therefore subject to Temporary Recommendations issued by the International Health Regulations Emergency Committee on Polio Eradication (issued as of 1 November 2022).

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.
