Various triggers have been found, including some viruses from the same virus group as polio: enterovirus 68, enterovirus 71, and coxsackievirus A7. [1] [2] These are suspected in many cases of acute flaccid myelitis.

[43] Paralytic poliomyelitis occurs in less than 1% of poliovirus ...
The following year, the World Health Assembly voted for the Global Polio Eradication Initiative. At the time, there were 125 countries with endemic polio. [4] Efforts were built upon those used to control wild poliovirus in the Americas in the early 1980s, and on lessons from smallpox eradication. [1] Its first coordinator was Nick Ward. [5]
