What Are The Symptoms Of Polio?

Polio (poliomyelitis) is a severe illness caused by a virus called poliovirus. The majority of polio cases are asymptomatic or occur without noticeable symptoms. There are two classifications of symptomatic polio: paralytic and non-paralytic. Poliovirus is highly contagious and can be spread through direct contact with an infected individual through feces, food, and the water supply. Once poliovirus enters a host, it colonizes in the intestinal and throat tissues. Without swift medical intervention, the virus mobilizes in the bloodstream and spreads throughout the body. Thankfully, a vaccine to prevent polio is available. Polio can be detected through secretions in the throat, cerebrospinal fluid, and stool. Because polio cannot be cured, treatment consists of preventing complications and managing symptoms.
