Description:The Global Polio Eradication Initiative (GPEI) was established in 1988 by the World Health Assembly to interrupt Transmission of wild polioVirus (WPV); completion of this initiative was declared a programmatic emergency of public health in January 2012. Polio cases are detected through Surveillance for acute flaccid paralysis (AFP) with linked stool specimens tested for polioViruses (PVs) at accredited laboratories within the Global Polio Laboratory Network (GPLN). AFP Surveillance findings are supplemented by tTesting sewage samples (environmental Surveillance) collected at selected sites. Virologic data guide where targeted immunization activities should be conducted or improved. Key performance indicators are used to 1) monitor AFP Surveillance quality at national and subnational levels to identify gaps where PV Transmission could occur undetected; 2) provide evidence of where PV circulation has been interrupted; and 3) allow timely detection of an outbreak. Standardized Surveillance indicators allow progress to be monitored over time and compared among countries. This report presents AFP Surveillance performance indicators at national and subnational levels for countries affected by polio during 2011-2012, and Trends in environmental Surveillance, updating previous reports. In the 19 countries with Transmission of PV (WPV and/or circulating vaccine-derived polioVirus [cVDPV]) during 2011-2012, national performance indicator targets were met in 12 (63%) countries in 2011 and 13 (68%) countries in 2012. Seven countries (37%) in 2011 had ≥80% of the population living in areas meeting performance indicators, increasing to nine countries (47%) in 2012. Performance indicators for timely reporting of PV isolation and characterization were met in four of six World Health Organization (WHO) regions in 2011 and five regions in 2012. To achieve global polio eradication, efforts are needed to improve and maintain AFP Surveillance and laboratory performance.
