  • More than 6 months has passed since a case of wild poliovirus was reported in Syria or Iraq. This is testimony to the dedication of local health workers and the significant efforts of many partners to reach all children with supplementary immunization activities.

All cases of wild poliovirus type 1 reported this week were from Pakistan. In 2014, Pakistan has accounted for 83% of cases reported globally. Khyber Pakhtunkhwa province and the Federally Administered Tribal Areas (FATA) constitute the most heavily infected area of the world, with 73% of cases worldwide occurring within these provinces.

The risk of international spread of polio from Pakistan remains high. The bulk of cases in neighbouring Afghanistan are linked to cross-border transmission with Pakistan, and the outbreak affecting the Middle East originated in Pakistan.

  • Halfway into 2014, Pakistan is just six wild poliovirus cases short of exceeding their 2013 total. North Waziristan – which is responsible for 63% of the country’s cases this year – remains inaccessible, although more than 400,000 former residents have fled recent conflict in the area. Efforts are under way to vaccinate as many children of internally displaced families as possible, including through routine immunization services and fixed vaccination posts at major transit sites.

The Technical Advisory Groups (TAGs) on Polio Eradication in Afghanistan and Pakistan met in Islamabad, Pakistan, last week.

EXECUTIVE SUMMARY

Eighteen months ago, as 2012 drew to a close, optimism was running high for the Global Polio Eradication Initiative. Polio transmission in India had been interrupted. The three remaining endemic countries (Pakistan, Nigeria, Afghanistan) had made significant programmatic improvements. Some believed that success was imminent; that polio would soon be history.
Within a matter of months, this optimism quickly unwound:

• Targeted killing of polio vaccinators in Pakistan shocked the world and created major operational constraints.
