Because C. difficile forms spores that can survive on environmental surfaces for months, environmental contamination is a major route of transmission. Several approaches have been developed to enhance standard cleaning of hospital rooms to eradicate the pathogen, but efficacy data are sparse. Researchers at one academic medical center that had already implemented multiple measures to reduce C. difficile infection (CDI) conducted a prospective controlled study of CDI incidence before and after terminal disinfection of rooms previously occupied by CD-infected patients using ultraviolet wavelength C germicidal irradiation (UVGI).
