Outbreak Countries

Outbreak countries are those affected by either re-infection due to an imported poliovirus, or the emergence of a circulating vaccine-derived poliovirus. Full implementation of international outbreak response guidelines are necessary to again stop such outbreaks. All countries will remain at risk of polio until the disease has been completely eradicated from the world. Until then, the best way for countries to minimise the risk and consequences of polio infection is to maintain strong population immunity levels through high vaccination coverage, and strong disease surveillance in order to rapidly detect/respond to polio.
