“Canada quietly updates COVID-19 guidelines on risk of airborne spread”

“Canada quietly updates COVID-19 guidelines on risk of airborne spread” Adam Miller · CBC News · Nov 04, 2020 https://www.cbc.ca/news/health/coronavirus-canada-aerosol-transmission-covid-19-1.5789906 Canada has quietly revised its guidelines on how COVID-19 spreads to include the risk of aerosol transmission, weeks after other countries and international health organizations acknowledged the airborne threat of the coronavirus. The Public Health […]

Objectives: Because the detection of SARS-CoV-2 RNA in aerosols but failure to isolate viable (infectious) virus are commonly reported, there is substantial controversy whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted through aerosols. This conundrum occurs because common air samplers can inactivate virions through their harsh collection processes. We sought to resolve […]

Purpose The purpose is to understand the role of public leadership during the COVID-19 pandemic and advocate for a more active role of public health professionals in helping manage the crisis. Design/methodology/approach The authors use the framework developed by Boin et al. (2005) on crisis leadership. The authors focus on three of the core tasks – sense-making, […]

Galloway, Heather, and Javier Salas. 2020. “A room, a bar and a classroom: how the coronavirus is spread through the air.” EL PAÍS, October 28, 2020.

The risk of contagion is highest in indoor spaces but can be reduced by applying all available measures to combat infection via aerosols. Here is an overview of the likelihood of infection in three everyday scenarios, based on the safety measures used and the length of exposure. Methodology: we calculated the risk of infection from […]

In 2003, when SARS had infected thousands, killed hundreds, and caused a worldwide scare, Lidia Morawska was studying the effects of inhaling fine particles of pollution. But then the World Health Organization asked Morawska, a physicist at the Queensland University of Technology, to join a team in Hong Kong trying to understand how the coronavirus […]

Viroscientists in Rotterdam, The Netherlands demonstrate in ferret study that SARS-CoV-2 can remain infectious while travelling through air ducts with multiple right angles.

Kutter, Jasmin S., de Meulder, Dennis et al. 2020. “SARS-CoV and SARS-CoV-2 are transmitted through the air between ferrets over more than one meter distance.” BioRxiv, October 19, 2020.

SARS-CoV-2 emerged in late 2019 and caused a pandemic, whereas the closely related SARS-CoV was contained rapidly in 2003. Here, a newly developed experimental set-up was used to study transmission of SARS-CoV and SARS-CoV-2 through the air between ferrets over more than a meter distance. Both viruses caused a robust productive respiratory tract infection resulting […]
