Role in Myalgic Encephalomyelitis
Enteroviral infection has been posited as a key etiological factor in myalgic encephalomyelitis (ME). The evidence for persistent enteroviral infection is mixed.

Published Studies

 * In one study, enterovirus-specific RNA three standard deviations greater than controls was found in muscle biopsies of 20% of ME patients studied..
 * A Swedish study using the Fukuda criteria was unable to find evidence of any persistent enteroviral infection in fecal samples, muscle biopsies, or cerebrospinal fluid.
