What is the estimated frequency of paralysis in poliovirus infections?

Explanation:
Paralysis is a rare outcome of poliovirus infection. Most infections are asymptomatic or cause only mild illness, and only a small portion progress to affecting the motor neurons and causing acute flaccid paralysis. The option that describes paralysis as a rare event fits what is observed in polio epidemiology, making it the best choice. The other options imply rates that are much higher or much lower than what is typically seen in poliovirus infections.
