Tracking progress toward global polio eradication, 2010–2011

In January 2012, polio eradication was declared a "programmatic emergency for global public health" by the Executive Board of the World Health Organization (WHO) (1). Since the Global Polio Eradication Initiative (GPEI) began in 1988 (2), progress has been tracked by surveillance of acute flaccid paralysis (AFP) cases and testing of linked stool specimens for polioviruses (PVs) in WHO-accredited Global Polio Laboratory Network (GPLN) laboratories, complemented by sewage testing (environmental surveillance) in selected areas. Monitoring AFP surveillance quality at national and subnational administrative levels using standard performance indicators identifies potential gaps where PV circulation might go undetected; monitoring specimen transport and laboratory reporting timeliness identifies areas where reporting delays could lead to late response, permitting ongoing transmission. This report provides an assessment of 2010–2011 performance indicators for AFP surveillance at national and subnational levels in
