Colitis caused by Clostridium difficile is contagious, according to MedicineNet. This illness is the infection of the colon by Clostridium difficile bacteria, and it develops when the bacteria produce toxins that damage the lining of the colon.
The symptoms of C. difficile include abdominal pain, diarrhea and fever. Complicated C. difficile causes rupture of the colon, dehydration and the spread of the infection to the abdominal cavity or the body. A severe infection can become life-threatening, notes MedicineNet.
The main cause of C. difficile is treatment with antibiotics. Antibiotics prevent normal colonic bacteria from controlling the multiplication of C. difficile, resulting in colitis. The infection mostly occurs in patients in the hospital, reports MedicineNet.
