Abstract: of coronavirus disease (COVID-19) had been reported globally since December 2019 (1), severely burdening the healthcare system (2). The extremely fast transmission capability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has aroused concern about its various transmission routes.The main transmission routes for SARS-CoV-2 are respiratory droplets and close contact (3). Knowing the extent of environmental contamination of SARS-CoV-2 in COVID-19 wards is critical for improving safety practices f… Show more

“…The study found that SARS-CoV-2 can survive up to three days on some surfaces, like plastic and steel, and that aerosol transmission is plausible since the virus can remain viable and infectious in the air for hours. These findings echo those of Chen et al (2004) on environmental contamination with SARS-CoV-1, and are consistent with evidence for aerosol distribution of SARS-CoV-2 found by Guo et al (2020), but are inconsistent with the current WHO stance that SARS-CoV-2 is not transported by air. However, the possibility of airborne transmission would call for different mitigation efforts to prevent spreading and is thus an important area of study.…”

“…In the case of a safe distance to avoid spread, recommendations originate from modelling, simulations and lessons learnt from outbreaks of other viruses. Recent work by Guo et al suggests that maybe none of these distances is fully protective for Covid-19 with spread of up to 4 m reported in a hospital setting although it is not clear if particles travelling this far are infectious [1].…”

“…Inside the adjusting tank of Jinyintan Hospital and Huoshenshan Hospital, SARS-CoV-2 in aerosols was found at a level of 285 copies/m 3 and 603 copies/m 3 , respectively ( Table 1 and Table S1). They were of comparable levels to SARS-CoV-2 detected in intensive care units (ICU) 3,22 and exhibited high transmission potential via aerosol deposition. On the contrary, aerosol SARS-CoV-2 was not detected in downstream wastewater To further examine whether the aerosol and soil SARS-CoV-2 was derived from wastewater treatment sector, we analyzed SARS-CoV-2 viral RNA in waters from different treatment tanks.…”
