Surveillance
Surveillance costs cover the detection and reporting of acute flaccid paralysis (AFP) cases. In 2012-2013, 6% of the total budget is allocated to surveillance.
AFP cases are reported through an extensive informant network of people who first report cases and through active searches in health facilities. This surveillance network reports from every district in the world on a weekly basis. Two stool samples are taken from a paralysed child and sent to the appropriate laboratory, where they are tested for poliovirus. The Global Polio Laboratory Network, comprised of 145 facilities, tested over 201,000 stool samples in 2011 alone.
