What are the main features of the Poliomyelitis?
Poliomyelitis is a common disease that has been affecting thousands of people for several years. It is a viral infection. Majority of people who are affected by the virus develop an illness that resembles a flu which is known as the non-paralytic poliomyelitis. Secondary disruption of the brain and the spinal cord is accompanied by either infection or death of motor neurons which consequently leads to weakness of the muscles or atrophy. It has become known recently that some of the individuals who have been already affected by the paralytic poliomyelitis are subjected to the development of new symptoms after several years of stable function, these new symptoms are known as the post-polio syndrome or the late sequala of poliomyelitis. In addition, the national centre for health statistics states that most of polio survivors may be at risk of post- polio syndrome. Several researches approximate that post- polio syndrome affects from forty to eighty percent of polio survivors. In some cases, the same symptoms may appear and gradually get worse, and in other cases the symptoms that re-appear are extremely severe. This justifies the reason of Robert starting to have these problems recently.
