The diagnosis of C difficile colitis should be suspected in any patient with diarrhea who has received antibiotics within the previous 3 months, has been recently hospitalized, and/or has an occurrence of diarrhea within 48 hours or more after hospitalization.
Although most patients develop diarrhea during or shortly after starting antibiotic therapy, 25%-40% of patients may not become symptomatic for as many as 10 weeks after completing antibiotic therapy.
C difficile should also be a suspected cause of diarrhea in community dwellers without previous hospitalization or antibiotic exposure.
