Poliovirus, the causative agent of poliomyelitis, is a human enterovirus and member of the family of Picornaviridae. A single-stranded positive-sense RNA virus. Poliovirus is one of the most well-characterized viruses, and has become a useful model system for understanding the biology of RNA viruses.
