Ong SWX, Tan YK, Chia PY, et al. - As coronaviruses have been implicated in nosocomial outbreaks with environmental contamination as a route of transmission and similar reports have been observed for nosocomial transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), researchers here aimed at ascertaining the mode of transmission and extent of environmental contamination. From January 24 to February 4, 2020, surface environmental samples were taken at 26 sites from airborne infection isolation rooms (12 air exchanges per hour) with anterooms and bathrooms of 3 patients at the dedicated SARS-CoV-2 outbreak center in Singapore. They used SKC Universal pumps for air sampling on 2 days. Collection of samples was performed on 5 days over a 2-week period. Analysis revealed that patients with SARS-CoV-2 had significant environmental contamination through respiratory droplets and fecal shedding. This indicates the environment as a possible medium of transmission and supports the necessity for strict adherence to environmental and hand hygiene.
