Detection of Herpesviruses and Parvovirus B19 in Gastric and Intestinal Mucosa of Chronic Fatigue Syndrome Patients

They tested 48 CFIDS patients and 35 healthy controls.
For EBV, HHV6, HHV7 there were no big differences between patients and controls .
These virusses are probably not relevant for CFS.

Parvovirus B19 DNA was detected in 40% of the patients, and in less than 15% of the controls.
Parvovirus B19 may be involved in the pathogenesis of CFS, at least for a subset of patients.
