There does not appear to be any relationship between recurrence and the severity of the original infection or the treatment used.

After the first recurrence about half of the patients continue to have repeated episodes often over a period of years. Recurrent disease can be caused by germination of residual C. difficile spores that are not killed and remain in your colon after treatment. Reinfection with a new strain of C. d
