Symptoms of polio can range from flu-like infections to total paralysis within several hours. poliovirus. central nervous system. the epidemiology of poliomyelitis provides an intriguing and instructive case study. Polio survivors and their medical professionals are encouraged to work together to find the causes of any symptom and provide appropriate treatment (for example, medication for hypothyroidism, hypertension, diabetes, irritable bowel syndrome, and so on). Polio, also known as poliomyelitis, is caused by the poliovirus. Those with other, more obvious causes (like trauma) are excluded . the pathophysiology of muscle weakness in PPS still remains an issue of debate.5 In acute poliomyelitis, viral invasion of the central nervous system (CNS) results in the destruction of motor neurons in the anterior horns of the bulbar and spinal cord regions. The remaining 5% of the cases are divided in two major groups: non-paralytic poliomyelitis, representing 4% of the cases, and paralytic poliomyelitis, representing around 1% of the cases.

Our knowledge of the pathology and pathogenesis of human poliomyelitis has developed slowly over a period of many years, and most of the present day concepts are still so young that they have not yet influenced to any appreciable extent studies on the pathologic physiology of the disease. The muscles affected by polymyositis are the skeletal muscles (those involved with making movements) on both sides of the body.

The poliovirus is a virus that destroys nervous system causing paralysis. In this severe condition, the virus spreads from the intestine to the brain and spinal cord that causes permanent damage to the nerves that control muscle movement.

Paralytic polio is fatal in at least 2% to 5% of child cases and 15% to 30% of adolescent or adult cases. Because of the nature of the disease, the early lesions of acute poliomyelitis or infantile paralysis in man are accessible for study only at necropsy, and it is from such material that the cytopathologic picture has been built. Only a polio survivor can develop PPS, it is not contagious. The prognosis for patients with polio depends on the extent of damage caused by the poliovirus. Many patients may have few if any symptoms and will have an excellent prognosis. However, the prognosis worsens when patients begin to show symptoms of paralysis, especially with decreased ability to breathe or swallow.
