Question

Paralysis of legs, convulsions and stiffness of neck is due to affected by

• A. Measles
• B. Rabies
• C. Polio
• D. Trachoma

Answer 1

The correct option is C Polio

Poliomyelitis is a disease that results from infection of poliovirus. Poliovirus spreads along nerve fibres. When it multiplies in the nervous system, the virus can destroy nerve cells (motor neurons) which activate skeletal muscles. These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous innervation - a condition known as acute flaccid paralysis (AFP). Typically, in patients with poliomyelitis muscles of the legs are affected more often than the arm muscles. Approximately 90% to 95% of infections cause no symptoms. Another 5 to 10% of people have minor symptoms such as: fever, headache, vomiting, diarrhea, neck stiffness and pains in the arms and legs. These people are usually back to normal within one or two weeks. In about 0.5% of cases there is muscle weakness resulting in an inability to move. This can occur over a few hours to few days. The weakness most often involves the legs but may less commonly involve the muscles of the head, neck and diaphragm.

Therefore, the correct answer is option C.
