NIH study shows that airborne transmission of COVID could lead to more severe disease

NIH Study: COVID-19 severity could depend on route of infection: Infection through inhaling #Airborne virus could lead to more severe disease than infection from fomites (contact w/ contaminated objects.) To test it, hamsters were infected via the different routes. NIH Study: COVID-19 severity could depend on route of infection: Infection through inhaling #Airborne virus could […]

CDC Releases New Ventilation Guidelines For Indoor Environments To Reduce Covid-19 Risk

https://www.forbes.com/sites/victoriaforster/2020/12/08/cdc-releases-new-ventilation-guidelines-for-indoor-environments-to-reduce-covid-19-risk/ The U.S. Centers for Disease Control and Prevention (CDC) today released new guidelines on the use of ventilation strategies to reduce the risk of exposure to the SARS-CoV2 coronavirus in indoor settings. Indoor environments have long been known to be riskier for the transmission of viral particles than outdoor environments, largely due to relative lack of […]

Doctors, engineers call on Ontario to address airborne spread of COVID-19 in open letter “Ventilation not Ventilators”

Nearly three dozen engineers and doctors in Ontario are calling on the Health Ministry to better inform the public about the risks of airborne transmission of COVID-19, and improve ventilation standards across the province. In a letter, 21 doctors and 12 engineers and other scientists call on Ontario to update the province’s COVID-19 guidelines, regulations and communication to […]

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.     Ferret Study Reinforces Role of Aerosols in SARS-CoV-2 Spread Using an elaborate apparatus, researchers find that the virus spreads via aerosolized particles between ferrets […]

Japanese supercomputer shows that low humidity dramatically increases indoor spread of aerosols.

Japan supercomputer shows humidity affects aerosol spread of coronavirus Rocky Swift https://www.reuters.com/article/health-coronavirus-japan-supercomputer/japan-supercomputer-shows-humidity-affects-aerosol-spread-of-coronavirus-idINL4N2H51NN TOKYO, Oct 14 (Reuters) – A Japanese supercomputer showed that humidity can have a large effect on the dispersion of virus particles, pointing to heightened coronavirus contagion risks in dry, indoor conditions during the winter months. The finding suggests that the use of […]
