Any member of the Picornaviridae family, genus Enterovirus; the name is derived from the group designation enteric cytopathogenic human orphan virus.



(acronym for enteric cytopathogenic human orphan virus), a minute virus containing one strand of RNA and lacking an outer protein layer. An orphan virus is a virus detected under laboratory conditions but not associated with any known disease. However, it has been found that this is not true of echovirus. Echovirus belongs to the genus Enterovirus of the family Picornavirus. Many of the more than 30 serotypes live in the human intestine without causing any symptoms of disease. Some, however, are the causative agents of aseptic meningitis, gastroenteritis, and respiratory diseases.
