Evidence Transmission Can Be Interrupted End 2014

Lessons learned from the India experience have informed emergency activities within the three remaining endemic countries. Intensifying these approaches forms a key component of the GPEI’s activities to interrupt transmission (outlined in detail under Objective 1), but a more fundamental question is whether the program can achieve interruption of wild poliovirus. Though the exact date of interruption cannot be guaranteed, as various factors may always intervene, new evidence of progress in eradication in the remaining endemic countries shows that the eradication effort turned a corner in 2012 and is now on a trajectory to interrupt transmission by the end of 2014. As of January 16, 2015, the last transmitted case was in Pakistan on December 15, 2014. For now, the milestone for ending transmission in 2014 appears to be holding.
One of the critical obstacles to interrupting WPV transmission is driving up vaccination coverage in order to reach the immunity levels needed to interrupt transmission. Accessing certain ‘at-risk’ populations – particularly those children that have persistently been missed – has been a key challenge. 

2012 saw major progress in SIA quality and accessing of missed children. Endemic countries showed measurable improvements in the quality of immunization campaigns, leading to more children being vaccinated.
