Pakistan is one of only three countries in the world with ongoing wild poliovirus transmission, alongside Afghanistan and Nigeria.

International Health Regulations

Pakistan is classified by the International Health Regulations (IHR) as a state infected with WPV1, cVDPV1 or cVDPV3 with potential risk of international spread, and as a state infected with cVDPV2, with potential risk of international spread.  It is therefore subject to temporary recommendations as of May 2019.

Key at-risk: no longer poliovirus-infected, but at high risk of outbreaks
Outbreak: has stopped indigenous WPV circulation but affected by outbreak of imported WPV or circulating vaccine-derived poliovirus
Endemic: has never stopped indigenous wild poliovirus (WPV) circulation

Travel Recommendations

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.
