(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.

Additionally, echovirus 9 PCR from sample 5 detected an expected product at 112 bp.
During 2006-2008, the five most frequently detected enteroviruses were coxsackievirus B1 (CVB1), echovirus 6, echovirus 9, echovirus 18, and coxsackievirus A9; these accounted for 54% of total known serotyped detections during that period.
Echovirus 9 accounted for 21.5%, 41.0%, and 18.9% of detections with known serotypes during 2002, 2003, and 2004, respectively.
Echovirus 9 was the predominate enterovirus serotype circulating in the eastern United States during 2003 (4) and was identified as the likely etiologic agent in this outbreak.
Echovirus 9 (E9) and echovirus 30 (E30) have been associated frequently with outbreaks of aseptic meningitis (3-5).
Of the 1672 nonpolio enterovirus isolates, echovirus 30 was the predominant serotype and accounted for 27.5% of all isolates, followed by echovirus 11 (13.8%), echovirus 9 (8.7%), and echovirus 6 (6.9%).
During 1993-1996, of the 3209 nonpolio enterovirus isolations reported, echovirus 9 was the predominant serotype reported (12.7%), followed by coxsackievirus B5 (11.5%), echovirus 30 (9.5%), coxsackievirus A9 (6.6%), coxsackievirus B2 (6.2%), echovirus 6 (5.1%), and echovirus 11 (4.5%).
The rates of isolation of echovirus 9 from stool and CSF specimens of case-patients (19% and 9%, respectively) were lower than those obtained in previous investigations, possibly resulting from the timing of sample collection following onset of illness; the small volume of sample obtained; or loss of virus in the specimen during handling, storage, or shipment.
