3rd Country Confirms Type-1 Wild Poliovirus Case
According to the Pakistan-based Express Tribune, type-1 wild poliovirus (WPV1) was reported in a child from North Waziristan. In addition, Islamabad's Pakistan National Polio laboratory confirmed the onset of paralysis on April 22, 2022.
This is the third case of wild polio (Afghanistan and Malawi) recorded globally in 2022.
The detection of WPV1 outside the two countries where the disease is endemic demonstrates the continuous risk of international spread of the disease until every corner of the world is free of WPV1, said the World Health Organization (WHO) in March 2022.
Two of the three types of wild poliovirus have been eradicated (WPV2 and WPV3).
Secretary Health Aamir Ashraf commented in the media report, “The case has appeared in Southern Khyber Pakhtunkhwa where the poliovirus was detected in (DI Khan and Bannu divisions) the environment year (2021) and where an emergency action plan is already being implemented.”
The WHO says countries should also maintain systematically high routine immunization coverage rates (>90%) to minimize the consequences of any new poliovirus introduction.
The health secretary added, “The National and Provincial Polio Emergency Operations Centres have deployed teams to conduct a full investigation of the recent case, while emergency immunization campaigns are underway to prevent further spread of the wild poliovirus in Pakistan.”
The WHO’s International Travel and Health recommend that all travelers to polio-affected areas be fully vaccinated against polio.
And residents and visitors for more than four weeks from infected areas should receive an additional dose of OPV or IPV within one to 12 months of travel.
The U.S. CDC issued an Alert - Level 2, Practice Enhanced Precautions, to notify international travelers of polio outbreaks in Asia and Eastern Europe on March 21, 2022.
