Abstract
The importance of SARS-CoV-2 transmission via contact routes and its stability on surfaces is becoming increasingly recognised. There is ongoing concern that patients can become infected through person-to-person spread and environment-to-person spread. This study assessed whether SARS-CoV-2 viral RNA can be detected in the environment either on staff members' personal protective equipment (PPE), on high-touch surfaces or around the bedspace of COVID-19-positive patients in a range of different ward settings to evaluate if there was any contamination of these. Results showed all PPE and high-touch surface swabs were negative. All swabs taken in the negative-pressure room where aerosol-generating procedures (AGPs) were being undertaken detected viral RNA (5/5 positive), whereas there was minimal contamination in the intensive therapy unit (1/5 positive) and none detected in the cohort bay. These findings would be consistent with the understanding that areas where AGPs are regularly performed are at higher risk of environmental contamination.
