Clostridium difficile is the most common cause of healthcare-associated infectious diarrhea. Affecting predominantly elderly patients with comorbidities and antibiotic exposure, C. difficile–associated diarrhea (CDAD) is linked to additional morbidity and mortality, prolongation of hospital stay, and higher costs.
