Early and accurate diagnosis is essential for optimal treatment of individuals with Clostridium difficile infection (CDI) and for implementation of effective infection control procedures. The decision about which diagnostic test to use is an important one that should be based on test sensitivity, specificity, and predictive value. The challenges of CDI go beyond rapid identification and management of symptomatic patients. Asymptomatic carriage has long been suspected in C. difficile transmission, but it may play a larger role than previously thought. Emerging information also shows that patients treated for CDI remain colonized for many weeks after symptom resolution. In fact, stool culture positivity increases during the first weeks following treatment completion. Treatments that reduce the duration and degree of asymptomatic shedding could have added benefit for reduced transmission.
