The Polio Surveillance System

On the occasion of World Polio Day, 24 October 2017, the last of a three-part animated series.

The search for the poliovirus is triggered when any child is found with acute flaccid paralysis. From the most remote communities to the laboratory, the World Health Organization makes sure that the components of the surveillance system work together so that if the poliovirus is circulating anywhere in the world it will be found – and stopped.
