title: Progress toward poliomyelitis eradication - Afghanistan and Pakistan, January 2011-August 2012.
abstract: In 1988, the World Health Assembly resolved to eradicate polio, which led to the establishment of the Global Polio Eradication Initiative (GPEI). In 2012, however, the transmission of indigenous wild poliovirus (WPV) continued uninterrupted in Afghanistan, Pakistan, and Nigeria, leading the World Health Assembly to declare completion of polio eradication a programmatic emergency for global public health. This report updates previous reports and describes polio eradication activities and progress in Afghanistan and Pakistan during January 2011-August 2012, as of September 9, 2012. During 2011, 80 WPV cases were confirmed in Afghanistan, compared with 25 WPV cases in 2010; 17 WPV cases were confirmed during January-August 2012, compared with 34 WPV cases for the same period in 2011. In Pakistan, 198 WPV cases were confirmed in 2011, compared with 144 WPV cases in 2010; 30 WPV cases were confirmed during January-August 2012, compared with 88 WPV cases during the same period in 2011. During January 2011-August 2012, no WPV type 3 (WPV3) cases were confirmed in Afghanistan, and four confirmed WPV3 cases and one case with coinfection of WPV3 and WPV type 1 (WPV1) were reported in Pakistan. Violence targeting vaccinators has occurred previously in Afghanistan and recently in Pakistan. To progress further toward interruption of WPV transmission within their countries and across their shared border, the governments of Afghanistan and Pakistan might consider reviewing the implementation of their national emergency action plans and determine how to enhance the safety of vaccination teams within conflict-affected areas of both countries.
