What is the typical incubation period for paralytic poliomyelitis?

• A. 1-2 days
• B. 2-3 weeks
• C. About 7-14 days; range 3-35 days.
• D. Several months

Answer: (C)

Incubation period is the time from exposure to the onset of symptoms. For paralytic poliomyelitis, after the virus enters the body and begins to spread, neurological signs typically appear about one to two weeks later. The common window is around 7–14 days, with a broader range from roughly 3 days to 35 days. So the option stating about 7–14 days, with a range of 3–35 days, best matches what is usually seen. Times like 1–2 days are too short to account for the disease’s progression, and several months is far outside the typical incubation interval.
