Echovirus is a polyphyletic group of viruses associated with enteric disease in humans.
The name is derived from "enteric cytopathic human orphan virus".
These viruses were originally not associated with disease, but many have since been identified as disease-causing agents.
Rare symptoms include viral meningitis, which affects the brain and spinal cord.
Doctors may give an immune-system treatment called IVIG, which can help those with weak immune systems.
