Picornaviridae

A viral family made up of the small (18–30 nanometer) ether-sensitive viruses that lack an envelope and have a ribonucleic acid (RNA) genome. The name is derived from “pico” meaning very small, and RNA for the nucleic acid type. Picornaviruses of human origin include the following subgroups: enteroviruses (polioviruses, coxsackieviruses, and echoviruses) and rhinoviruses. There are also picornaviruses of lower animals (for example, bovine foot-and-mouth disease, a rhinovirus). See Animal virus, Coxsackievirus, Poliomyelitis, Rhinovirus
