It is a VIRUS. Poliovirus, the causative agent of poliomyelitis, is a human enterovirus and member of the family of Picornaviridae.
Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA genome that is about 7500 nucleotides long.[3] The viral particle is about 30 nanometres in diameter with icosahedral symmetry. Because of its short genome and its simple composition-only RNA and a non-enveloped icosahedral protein coat that encapsulates it-poliovirus is widely regarded as the simplest significant virus.[4]
Poliovirus was first isolated in 1909 by Karl Landsteiner and Erwin Popper.[5] In 1981, the poliovirus genome was published by two different teams of researchers- by Vincent Racaniello and David Baltimore at MIT[6] and by Naomi Kitamura and others at the State University of New York, Stony Brook.[7] Poliovirus is one of the most well-characterized viruses, and has become a useful model system for understanding the Biology of RNA viruses.
Poliomyelitis, often called polio or infantile paralysis, is an acute viral infectious disease spread from person to person, primarily via the fecal-oral route.[1] The term derives from the Greek poliós (πολιός), meaning "grey", myelós (µυελός), referring to the "spinal cord", and the suffix -itis, which denotes inflammation.[2]
Although around 90% of polio infections cause no symptoms at all, affected individuals can exhibit a range of symptoms if the virus enters the blood stream.[3] In about 1% of cases the virus enters the central nervous system, preferentially infecting and destroying motor neurons, leading to muscle weakness and acute flaccid paralysis. Different types of paralysis may occur, depending on the nerves involved. Spinal polio is the most common form, characterized by asymmetric paralysis that most often involves the legs. Bulbar polio leads to weakness of muscles innervated by cranial nerves. Bulbospinal polio is a combination of bulbar and spinal paralysis.[4]
