Timeline of recurrent C. difficile infection (CDI). Patient 1 was admitted to the LTCF in December and developed CDI in late January. Patient 2 was diagnosed with C. difficile infection during his initial hospitalization. Upon admission to the LTCF, he became Patient 1’s roommate for 4 months (box). Both patients had two recurrences of C. difficile infection which were temporally coincident. After irradiating their room with ultraviolet light in late April, neither patient has had a recurrence.
