What can result from a polio infection?

• A. Severe headache and fever
• B. Temporary fatigue and weakness
• C. Irreversible paralysis
• D. Persistent cough

Answer: (C)

Polio, or poliomyelitis, is a disease caused by the poliovirus that can lead to serious neurological complications. One of the most severe outcomes of a polio infection is irreversible paralysis, which occurs when the virus attacks the nerve cells in the spinal cord and brain, leading to muscle weakness and paralysis. This paralysis can affect various parts of the body and can be permanent, significantly impacting a person's mobility and quality of life.

The other options highlight symptoms that can occur during the course of a polio infection, such as severe headaches, fever, and temporary fatigue, but they do not encapsulate the most serious and enduring consequence of the disease. A persistent cough is not typically associated with polio, making it less relevant in the context of the disease's impact. Understanding the potential for irreversible paralysis emphasizes the importance of vaccination and preventative measures against polio.
