Which of these is the best description polio?

Poliomyelitis, commonly known as polio, is a highly infectious disease caused by the poliovirus. The virus mainly infects the spinal cord, and in some cases, can cause paralysis. Polio can range from an asymptomatic infection to causing various degrees of paralysis. While most cases of polio are mild, severe infections can lead to lifelong disability or even death. The virus primarily spreads through contact with an infected person’s feces or, less commonly, through contaminated food or water. Hence, the best description of polio is: “a highly infectious disease caused by the poliovirus, primarily affecting the spinal cord and characterized by the potential for paralysis."
