The groundbreaking research of Linsey Marr, an aerosols expert and professor of civil and environmental engineering at Virginia Tech, showed that the SARS-CoV-2 virus is airborne as opposed to traveling in large droplets that fall with gravity.

Canada’s culture of silence on airborne virus transmission leaves many confused on how to best avoid infection
It’s the dog days of the pandemic. We continue to follow public health guidance, which is getting less restrictive, as we wait for vaccines to end this crisis. We have learned so much over the last year about how to better protect ourselves, including critical information that COVID is likely transmitted predominantly via airborne spread.

The 60-Year-Old Scientific Screwup That Helped Covid Kill
Early one morning, Linsey Marr tiptoed to her dining room table, slipped on a headset, and fired up Zoom. On her computer screen, dozens of familiar faces began to appear. She also saw a few people she didn’t know, including Maria Van Kerkhove, the World Health Organization’s technical lead for Covid-19, and other expert advisers to the WHO.

Ontario, Alberta change policy limiting N95 masks as health-care workers demand greater access
At least two provinces have bowed to union pressure to let some health professionals use specialized respirator face masks when treating COVID-19 patients, sparking concern among infection-control experts this will undermine health workers’ trust in their advice.
Alberta and Ontario have reached agreements with unions to allow some health-care workers to use N95 respirator masks if they feel it is necessary. Nova Scotia’s largest nursing union is now calling on provincial officials to do the same.
