Echovirus refers to various viruses primarily in the family Picornaviridae. Echovirus takes its name from "enteric cytopathic human orphan virus". Echoviruses were originally not associated with disease but many have since been identified as disease-causing agents. The term "echovirus" was used in the scientific names of numerous species. However, all echoviruses are now recognized as strains of various species.
Summary
- Human echoviruses 1-7, 9, 11-21, 24-27, and 29-33 were merged into a single species, Enterovirus B of the genus Enterovirus, along with various coxsackieviruses.
- Human echovirus 8 was shown to be identical to Human echovirus 1 and was abolished as a species.
- Human echovirus 10 was classified as a strain of the species Reovirus type 1, currently named Mammalian orthoreovirus of the genus Orthoreovirus, which belongs to the family Reoviridae. As such, Human echovirus 10 is the only echovirus that does not belong to Picornaviridae.
- Human echoviruses 22 and 23 were merged into a single species: Parechovirus A of the genus Parechovirus.
- Human echovirus 28 was classified as the species Human rhinovirus 1A, which was later merged with other rhinovirus strains into the currently named species Rhinovirus A of the genus Rhinovirus.
- Human echovirus 34 was abolished as a species and classified as a strain of Human coxsackievirus A24, which is now classified as a strain of the species Enterovirus C of the genus Enterovirus.
