echovirus

 [ek´o-vi″rus]
a species of viruses of the genus enterovirus; the name was derived from the first letters of the description “enteric cytopathogenic human orphan.” At the time of the isolation of the viruses the diseases they caused were not known, hence the term “orphan,” but it is now known that they cause many different types of human disease, especially viral meningitis, diarrhea, and various respiratory diseases.

ECHO vi·rus

an enterovirus from a large group of unrelated viruses belonging to the Picornaviridae, isolated from humans; although many inapparent infections occur, certain serotypes are associated with fever and aseptic meningitis, and some appear to cause mild respiratory disease.

echovirus

/echo·vi·rus/ (ek´o-vi″rus) an enterovirus isolated from humans, separable into many serotypes, certain of which are associated with human disease, especially aseptic meningitis.

echovirus

(ĕk′ō-vī′rəs)
n. pl. echovi·ruses
Any of various enteroviruses of the gastrointestinal tract associated with certain diseases, such as viral meningitis, mild respiratory infections, and severe diarrhea in newborns.

ECHO vi·rus

, echovirus (ek'ō vī'rŭs, ek'ō-vī-rŭs)
An enterovirus isolated from humans; although there are many inapparent infections, certain of the several serotypes are associated with fever and aseptic meningitis, and some appear to cause mild respiratory disease.

ECHO vi·rus

, echovirus (ek'ō vī'rŭs, ek'ō-vī-rŭs)
Enterovirus isolated from humans; although there are many inapparent infections, some serotypes are associated with fever, aseptic meningitis, and other mild respiratory disease.

echovirus

some viruses, which were originally considered nonpathogenic, in the family Picornaviridae, genus Enterovirus. The name is derived from the first letters of the description 'enteric cytopathogenic human orphan', but similar viruses ECBO and ECPO (for bovine and porcine, respectively, and other species) are also recognized. At the time of the isolation of the viruses the diseases they caused were not known, hence the term 'orphan', but it is now known that some of these viruses produce many different types of human disease, especially aseptic meningitis, and diarrhea and various respiratory diseases. The members of the group are now included in the enteroviruses.
