Echoviruses of Enteroviruses Infection

 

D. New Enteroviruses

Newly identified picornaviruses that are not polioviruses are no longer classified separated into the species coxsackie and echovirus because of the ambiguities presented by overlapping host range variations. 5 new enteroviruses have been identified (68 - 71). Enterovirus 70 is the causative agent epidemics of acute haemorrhagic conjunctivitis that swept through Africa, Asia, India and Europe from 1969 to 1974. The virus is occasionally neurovirulent. Enterovirus 71 appears to be highly pathogenic and has been associated with epidemics of a variety of acute diseases, including aseptic meningitis, encephalitis, paralytic poliomyelitis-like disease and hand-foot-mouth disease. Enterovirus 72 is the designation assigned to hepatitis A virus, which, after it could be propagated in vitro, was shown to have the physical and chemical characteristics of enteroviruses.
