Why would EPA lie in 1989, and today, by claiming  only four Enteroviruses cause infectious disease?

6.   Enteroviruses: -----------------------------------------

Noun 1. enterovirus - any of a group of picornaviruses that infect the gastrointestinal tract and can spread to other
areas (especially the nervous system)
picornavirus - a group of single-strand RNA viruses with a protein coat
poliovirus - the virus causing poliomyelitis
hepatitis A virus - the virus causing hepatitis A
Coxsackie virus, coxsackievirus - enterovirus causing a disease resembling poliomyelitis but without paralysis
echovirus - any of a group of viruses associated with various diseases including viral meningitis and mild respiratory
disorders and diarrhea in newborn infants

The enteroviruses are a genus of (+)ssRNA viruses associated with several human and mammalian diseases.
Historically the most significant has been the Poliovirus (which is now nearly extinct). Coxsackie viruses (a
non-phylogenic group) are associated with human hand, foot and mouth disease. Echoviruses are a cause of many of
the non-specific viral infections. It is majorily found in intestine and can causes nervous disorders
Picornaviruses are viruses that belong to the family Picornaviridae. The name picornavirus means small RNA virus.
Virus classification involves naming and placing viruses into a taxonomic system.

Hand, foot and mouth disease
An echovirus is a type of RNA virus that belongs to the genus Enterovirus of the Picornaviridae family.

Includes Rhino viruses and Foot & Mouth Disease virus Enteroviral diseases/epidemics in the US occur in summer-fall.
Epidemic pleurodynia, hand-foot-and-mouth disease, herpangina, and poliomyelitis are caused almost exclusively by

They are spread throughout the body through the blood stream. Generally mild, but
infections may cause serious disease e.g. paralytic poliomyelitis, meningitis, or
myocarditis. (Merck)
