A number of studies over the last 20 years have explored the link of EBV and inflammatory bowel disease (IBD). In one very small study, 63 percent of patients with Crohn’s disease and 60 percent of ulcerative colitis patients had active EBV infection within the gut tissue. Another study found that in those with active ulcerative colitis, the Epstein Barr Virus had accumulated within and under the lining of the gut and within lymphocytes....
