Dilemma of increasing polio cases in Pakistan

Once again International Monitoring Board suggested more hard international travel restrictions on Pakistan. Independent Monitoring Board (IMB) is the board which suggested international travel restrictions on Pakistan and World Health Organisation (WHO) implemented it. Most alarmingly, Pakistani government has failed to implement the recommendations of IMB. It is pertinent to mention that IMB works on behalf of the international donor agencies and it issues reports regarding performance of the countries after every six months. In November 2012, IMB recommended that travel restrictions should be imposed on Pakistan and finally those recommendations were implemented on May 5. Over 200 polio cases have been registered in Pakistan in the year 2014 more than previous year, still few months to go to reach 2015. With 500,000 children yet to be vaccinated, Pakistan stands at a deplorable position on this year’s World Polio Day where it adds 85 percent of polio cases to the world. Such escalation of the disease creates many doubts about the stat’s measures and their outcome. Pakistan has been the major contributor to confirmed polio cases in 2013 as compared to Nigeria and Afghanistan – the only three remaining endemic countries. The polio eradication campaigns in Pakistan have been suffering from continuous setbacks as 27 polio workers have been assassinated since December 2012 during anti-polio immunization campaigns. Lack of an efficacious regime to tackle this pandemic was not enough, there had to be a conspiratorial element to further depreciate all the efforts. According to the 2013 World Health Organization report, 74 polio cases have been reported in Pakistan. However, 51 (69%) of the polio confirmed cases are from Federally Administered Tribal Areas (FATA), identifying it as the single major poliovirus reservoir in Pakistan. Moreover, the polio immunisation teams whose workers carry out door-to-door vaccinations should be killed as they are part of this sinister conspiracy against Muslims. Since this narrative got out, a series of attacks have been carried out targeting polio teams and killings dozens of health workers, mostly in the troubled areas of Khyber Phakhtunkhwa, Federally Administered Tribal Areas and Balochistan. As a result of which the most challenging issue for the government is how to retrieve the lost public trust where people in these areas now refuse to get their children immunised. The Government of Pakistan has highlighted multiple reasons for the growing polio endemic in Pakistan citing primarily militancy and ‘refusal families’. Militancy, especially in the Federally Administered Tribal Authority (FATA) and North Waziristan areas of Pakistan, may have compounded the polio campaign further by putting many children at risk. In spite of multiple supplementary immunization campaigns, the majority of confirmed polio cases identified in Punjab, Sindh and Khyber Pakhtunkhwa provinces in 2013 were from zones considered as low-violence areas.  This observation strongly contradicts the perception of militancy alone as an impediment for polio eradication in Pakistan. Lack of accurate polio vaccination coverage estimates and unaccountability of responsible officials are major reason for new polio cases in areas unaffected by violence. The example of measles epidemic in the southern part of Sindh (considered violence free zone) also contradicts the poor security viewpoint and highlights the failure of public health preventive strategies as the primary culprit. The 306 deaths and 14000 reported cases attributable to measles in 2012 highlights the poor immunization infrastructure, fraught with incorrect reporting. In 2012, Egypt health authorities found polio virus strains in two of its sewerage systems. Samples of this polio virus were traced to the environmental samples in Sukkur in Northern Sindh province of Pakistan again a low violence area. In 2013, the same strain from Pakistan found its way both, in the Palestinian and Israeli sewerage system via Egypt. Recently, 17 polio cases detected in four major cities of the war affected country of Syria have also been linked to the wild poliovirus strain from Pakistan.
A report suggests that all of the six polio cases reported from Quetta were solely because of their parents’ refusal to get their children vaccinated. Despite many edicts being issued by different clerics and religious scholars to unequivocally endorse the necessity of these immunisations, no adequate narrative seems to be in place and after having all these alarming facts in front of us, one wonders why the government has not adopted an effective policy on a war footing. Its contagiousness poses a threat to the rest of the world that is polio-free. Surely, we do not want to isolate ourselves from the rest of humanity. It is not only for our own sake but in order to be an active member of today’s dynamic global world that we need to get rid of this affliction as soon as possible.
Specific strategies related to anti-polio immunization campaigns in security compromised areas are urgently needed, close monitoring of anti-polio immunization campaigns is essential to ensure accountability and to overcome factors behind poor coverage.
