The discovery of poliovirus in six environmental samples nationwide is a cause for significant concern. Wild Polio Virus Type-I has been identified in six samples collected from five districts spanning Balochistan, Khyber Pakhtunkhwa, and Sindh provinces.
The virus’s presence in diverse samples, geographically separated, indicates its circulation and presents a serious threat. Regrettably, this resurgence follows a period of nearly complete success, raising hopes for achieving zero polio cases in Pakistan and neighboring Afghanistan.
The identification of an imported cluster in the detected samples draws attention to increased population movement between Pakistan and Afghanistan. Controlling the virus’s circulation and spread is challenging unless strict immunization measures are implemented at all entry and exit points. Establishing anti-polio vaccine facilities for Afghan children returning during repatriation is a prudent step to provide a level of defense against unrestricted circulation. The detection of the virus in 84 out of 90 samples this year should be a cause for alarm.
Recent revelations of a significant lapse in the immunization campaign add to the challenge. The consistent detection of the virus in environmental samples, coupled with incomplete delivery of the anti-polio vaccine to the targeted population, poses a potential major threat if not addressed promptly. Despite substantial investments in anti-polio campaigns, the health risk’s penetrability is rooted not only in insufficient immunization but also in the back-and-forth transmission of the virus between the two exposed countries.
Achieving complete virus eradication appears daunting when considering the numbers. Comprehensive vaccination campaigns are essential, but targeted efforts must also be initiated for mobile children. Cross-border transmission poses a substantial risk, particularly with a large number of children returning to their home country. The decision to vaccinate all Afghan nationals before deportation demonstrates a proactive policy shift, acknowledging the importance of preventing virus reintroduction from the neighboring country. The inter-ministerial meeting’s emphasis on synchronized efforts at repatriation centers and international border crossings, along with NADRA’s involvement for registration and digitization, underscores a coordinated approach to address vaccination challenges.
