airborne virus transmission

"properly fitting masks, 

moving our interactions outdoors, 

and improving our indoor air through ventilation upgrades (including easy solutions like 

opening windows and doors) and 

air filtration."

“Canada’s culture of silence on airborne virus transmission leaves many confused on how to best avoid infection” [Toronto Star]. “[M]any of our infectious disease and public health specialists — including our chief medical officers of health — seem to be unable to say the word ‘airborne’ or ‘aerosol’ out loud, and instead continue to emphasize measures such as deep cleaning and plexiglass panels…. Canada’s top public health organization, the Public Health Agency of Canada (PHAC), has produced strong, unbiased summaries of the evidence for airborne transmission…. But these summaries are very hard to find. They are not posted publicly, and PHAC has specifically requested that the reviews not be shared. In order to receive a copy, you first have to discover its existence, find the title and email PHAC for a copy. Evidently, our public health leaders have also not seen these documents, as they consistently dismiss the evidence. As such, Canadians remain confused as to the best methods of avoiding transmission. The focus is still on the neverending cleaning of surfaces and putting up splash guards (which are ineffective against airborne particles), instead of using properly fitting masks, moving our interactions outdoors, and improving our indoor air through ventilation upgrades (including easy solutions like opening windows and doors) and air filtration."
