Evaluation of Viral Surrogate Markers for Study of Pathogen Dissemination During Simulations of Patient Care.

During patient care simulations, cauliflower mosaic virus DNA and bacteriophage MS2 performed similarly as surrogate markers of pathogen dissemination. These markers disseminated to the environment in a manner similar to Clostridium difficile spores but were more frequently detected on skin and clothing of personnel after personal protective equipment removal.
