Poliomyelitis is a viral disease that can affect nerves and can lead to partial or full paralysis. It is caused by infection with the poliovirus which can be spread by direct person-to-person contact, by contact with infected mucus or phlegm from the nose or mouth, or by contact with infected feces. There are three basic patterns of polio infection: subclinical infections, nonparalytic, and paralytic. Symptoms vary based on the pattern of infection and can range from asymptomatic with subclinical poliomyelitis to partial or full paralysis. Treatment is aimed at controlling symptoms while the infection runs its course. Since the development of the polio vaccine, the incidence of the disease has been greatly reduced. The
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
