Poliovirus
Poliovirus (/ˈpoʊlioʊˌvaɪrəs/), is a member of the Enterovirus genus in the family Picornaviridae. The term "poliovirus" is derived from the Greek "polios" meaning "grey" and "virus" meaning "poison".
Classification
Poliovirus is classified into three serotypes: Poliovirus 1, Poliovirus 2, and Poliovirus 3. Each serotype is further divided into strains, based on their antigenic properties.
Structure
Poliovirus is a non-enveloped virus with an icosahedral symmetry. Its genome is a single-stranded positive-sense RNA molecule.
Pathogenesis
Poliovirus is the causative agent of Poliomyelitis, a disease that can cause paralysis and death. The virus primarily infects the gastrointestinal system and can spread to the central nervous system.
Transmission
Poliovirus is transmitted primarily through the fecal-oral route, although it can also be spread through respiratory droplets.
Prevention
Prevention of poliovirus infection is primarily through vaccination with either the inactivated poliovirus vaccine (IPV) or the oral poliovirus vaccine (OPV).
Treatment
There is no specific treatment for poliovirus infection. Management of the disease is primarily supportive, focusing on relieving symptoms and preventing complications.
