The operating room schedule will be reviewed each day by a research assistant for COVID-19 positive patients. Additionally, the research assistant will receive a page for every emergency surgery that takes place in the OR. OR PathTrac collection kits will be utilized for sampling of 48 specific locations/times throughout each case. These samples include: 11 samples that have been routinely used for S. aureus including nasopharyngeal. Normally there are 13, but 2 samples are included in the subsequent environmental locations: the adjustable pressure-limiting valve and agent dial at baseline and case end. 1 sample from the endotracheal tube tip at case end, as positive control. 12 environmental locations at case end including anesthesia machine and each of the air vents, 12 environmental locations matched after environmental cleaning, and 12 environmental locations matched after Surfacide Helios UV-C cleaning. The Surfacide Helios UV-C cleaning robots will be used after all normal environmental cleaning of the room has taken place. A transmission event will be defined as 2 samples with detection of SARS-CoV-2 by RT-PCR, with samples obtained from 2 distinct, epidemiologically-related reservoirs within a surveillance unit. The OR PathTrac software platform will process transmission dynamics in order to continually summarize the epidemiology of SARS-CoV transmission, with results updated daily as case-pair data is continually entered into the program. This information will be continually displayed to identify the most common reservoir of origin, the most common transmission locations (vectors), and involvement of key portals of entry (stopcocks). These will become improvement targets with feedback provided via automated failure mode analysis reports. The research assistants will use the reports to continually optimize the interventions during the observational period. The incidence and epidemiology of transmission will be mapped before and after UV-C treatment and positive samples for SARS-CoV-2 examined for viability by a UIHC laboratory.
