Is it true or false that polio always results in paralysis?

• A. True
• B. False
• C. It depends on the individual
• D. Only in severe cases

Answer: (B)

Polio, or poliomyelitis, is a viral infectious disease that can affect the nervous system and potentially lead to paralysis. However, it is important to understand that not all cases of polio result in paralysis. In fact, the majority of individuals infected with the poliovirus experience mild or asymptomatic illness, and only a small percentage develop more severe symptoms that can lead to paralysis. The range of outcomes from polio infection can vary greatly. Some people may experience flu-like symptoms without any long-term effects, while others may develop more serious complications. Paralysis occurs in approximately 1 in 200 infections, with those who do experience paralysis potentially facing lifelong disabilities. Thus, stating that polio "always" results in paralysis is inaccurate, making the correct answer to be false. This nuance is crucial in understanding the epidemiology of the disease and the importance of vaccination in preventing its more severe outcomes.
