Who is at highest risk for suffering complications from Polio?


Polio

Most people infected with the poliovirus show no clinical signs of illness. Fewer than 1 percent of persons infected with polio develop paralysis, the most severe complication of polio and many who develop paralysis recover with few or no permanent residual adverse health conditions. 1

Bulbar polio, the most severe and rarest form of paralytic polio (1-2 percent of all cases of paralytic polio), involves the cranial nerves and usually results in permanent paralysis with death in 25 to 75 percent of cases.2
