Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
Paralytic poliomyelitis occurs in less than 1% of poliovirus infections. Paralytic disease occurs when the virus enters the central nervous system (CNS) and replicates in motor neurons within the spinal cord, brain stem, or motor cortex, resulting in the selective destruction of motor neurons leading to temporary or permanent paralysis.
Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring in more than 80% of polio infections. The symptoms are caused by the damaging effects of the viral infection on the nervous system and typically occur 15 to 30 years after an initial acute paralytic attack.
Symptoms of this non-contagious disease include joint pain, muscle weakness, and mental and physical fatigue. Up to 40% of polio survivors get PPS, which begins 15 to 40 years after infection.
A few could contract meningitis if the polio virus attacks the covering of the spinal cord or brain. Polio is fatal for 2%-10% of those paralyzed or between 1 in 2,000 to 1 in 10,000 of those ...
Polio is an infection caused by a virus that mostly affects children under 5. Most people infected with polio don’t have any symptoms, but it can cause fever, headaches, vomiting and stiffness ...
Medications are usually not needed as hand, foot, and mouth disease is a viral disease that typically resolves on its own.

The CDC issued an alert about enterovirus D68, which can cause acute flaccid myelitis in rare cases.
