An Echovirus is a type of RNA virus that belongs to the genus Enterovirus of the Picornaviridae family. There are30 recognized Echovirus serotypes (1-9, 11-27, 29-30).

 

Mode of transmission: Fecal-oral route.

 

Enterovirus infections are common throughout the world. Virus watch studies suggest that 10 million to 15 million illnesses due to nonpoliovirus enteroviruses occur each year. Most infections are subclinical; clinical manifestations vary from mild to lethal and acute to chronic; associated with aseptic meningitis (mostly serotypes 2, 5, 6, 7, and 9), muscle weakness and paralysis, exanthems and enanthems, pericarditis, myocarditis, common cold, conjunctivitis, infantile diarrhea and acute febrile respiratory illnesses. The ‘gold standard’ for laboratory diagnosis of enteroviruses is cell culture isolation, followed by serotype dentification by neutralization assay.
