Initial clinical characteristics include fever, sore throat, headache, and vomiting, often with stiffness of the neck and back. In the minor illness these may be the only symptoms. The major illness (called also infantile paralysis), which may or may not be preceded by the minor illness, is characterized by involvement of the central nervous system, stiff neck, pleocytosis in the spinal fluid, and perhaps paralysis within a week. Bulbar poliomyelitis is a serious form involving the medulla oblongata and usually becomes evident within three days. The muscles of swallowing and breathing are affected, so that the patient has difficulty swallowing, speaking, and breathing. In all forms, there may be subsequent atrophy of groups of muscles, ending in contraction and permanent deformity.
There are three known types of poliovirus, each causing a different type of the disease. Most paralytic cases are caused by type 1. Poliovirus is found in the throat of a patient for the first few days of the disease, and in the intestines for a longer period, sometimes as long as 17 weeks. The disease spreads by means of droplets of moisture from an infected person's throat or by waste products from the intestines. The contagious period is 7 or more days from the time of onset of the disease. The poliovirus is short-lived, and cannot survive long in the air. The incubation period of polio is from 1 to 2 weeks, and occasionally as long as 3 weeks. Members of the family or other contacts may be carriers, but only for a short period of time.
poliomyelitis(1) A nonspecific term for inflammation affecting the spinal cord grey matter.
(2) Acute anterior poliomyelitis.
poliomyelitisNeurology A condition characterized by the selective destruction of anterior horn cells in the spinal cord and/or brain stem, ± leading to muscle weakness, paralysis and respiratory paralysis Etiology Viral, in particular poliovirus, but also coxsackie A7, enterovirus 71, and others Clinical If extreme, asymmetric flaccid paralysis Lab CSF pleocytosis, ↑ lymphocytes. Cf Aseptic meningitis.
poliomyelitisAn infectious disease, affecting mainly children and young adults, caused by one of three strains of polioviruses and spread by faecal contamination. The illness caused is usually mild and unimportant but the virus may attack the brain and spinal cord leading to extensive and fatal paralysis. In most cases polio causes no more than a few days of slight fever, sore throat, headache and vomiting. In some cases, however, stiffness of the neck and back, muscle aching and twitching occur and the condition progresses to paralysis. The use of polio vaccines (the spread of which has also been assisted by faecal contamination) has virtually eliminated the disease in developed countries. Also known as infantile paralysis.
poliomyelitisa paralytic disease in which cells of the CENTRAL NERVOUS SYSTEM become destroyed by the polio virus, leading to crippling, although most infections are not serious and the patient usually recovers full health. The disease can be kept in check by the administration of vaccines, the most popular being a live, attenuated type. In Western countries administration of such vaccines is now routine and the disease is very rare.
Patient discussion about poliomyelitis
Q. is polio contagus If i have a friend that had it when he was younger and it went away and then came back can i get it?
Q. Polio Syndrome pain One of my aunt is taking Neurontin for Post Polio Syndrome pain in her left leg and arm. she did not realize that she had so much pain and that it was keeping her from doing so many things. Is Neurontin recomended for this treatment and how does it help? Will she have problems with Neurontin if she take it long term? Neurontin is greatly helping the pain but not the fatique in these limbs. Should it help the fatigue?
