Abstract
Accurate surveillance for polio is essential for eradication. Surveillance systems for polio has been developed under the guidance of the global polio eradication initiative. Surveillance of cases of acute flaccid paralysis among children less than 15 years of age is a key component for a well functioning polio surveillance system. The surveillance system works through a network of surveillance medical officers, the responsibility of them lies in assisting the health services departments of all states and maintaining a network of acute flaccid paralysis reporting sites and rapidly investigating the cases. Surveillance activities begin when a child comes in contact with a healthcare provider who in turn informs the officer in charge of acute flaccid paralysis surveillance. The goal of the polio network laboratories is to provide accurate and timely results of wild poliovirus detection in stool samples of cases of acute flaccid paralysis. Strong linkages have been established between the acute flaccid paralysis surveillance system and the laboratory network. Laboratories complete poliovirus isolation and if poliovirus is isolated, these are submitted for intratypic differentiations. Acute flaccid paralysis surveillance in India has demonstrated that the eradication activities implemented in India led to dramatic reduction and restriction in the number of cases and geographic spread of poliovirus transmission.
