The world health organization has virtually eliminated it as a disease entity. I have never seen a case of polio and cite the symptoms from what I have been taught, not personal experience. Symptoms include a low grade temperature, occasional meningitis symptoms, - this is followed by a relapsing fever and flaccid paralysis. The paralysis varies in limbs affected and severity. Tendon reflexes are absent or markedly decreased.
Sensation is intact.
There is no treatment to reverse the problem. Poliovirus is an enterovirus. Infections with this virus are usually fairly asymptomatic. However, when the virus involves the nervous system, neurologic consequences often ensue. Motor neurons appear to be especially vulnerable to damage by this virus.
