For months now, I have felt like a broken record saying COVID-19 is airborne. Signing, shouting, and playing instruments can spread it farther and quicker. But, also breathing can too in enclosed spaces.

Studies continue to confirm those findings. Early on the in pandemic, the CDC used wording that said that COVID-19 was thought to spread mainly between people in close contact — about 6 feet — and “through respiratory droplets produced when an infected person coughs, sneezes or talks.”

That was a problem – many people I talked with in workplaces, churches, and schools took that as evidence that being in an enclosed space with proper physical distancing was enough (and why many people did not and still do not believe in masking inside buildings). For example, the thought was that being in a sporting event with loud shouting or church with singing was safe as long as you were 6 feet apart – due mainly to the misconception that the larger particles (like a sneeze you can see) were the way COVID-19 was transmitted.

From the beginning, we have known differently though:

โœ… April – A prestigious scientific group of leaders in infectious diseases and public health wrote a letter to the White House stating: “Currently available research supports the possibility that [coronavirus] could be spread via bioaerosols generated directly by patients’ exhalation,” the letter said.

โœ… July – 239 scientists from around the world published a letter to the WHO advocating for them to recognize the importance of airborne transmission. They note the strong potential for COVID-19 to spread around a room through the air. (BTW, many of these 239 scientists are the top, top, top of the field for virology, infectious diseases, and air quality.)

โœ… August – Doctors found COVID-19 in the air of patient’s rooms.

โœ… In May, I did a webinar discussing how COVID-19 can travel through the air around a room (up to 27 feet) – far and fast. In the webinar, we look at the science of how far COVID-19 can travel through shouting/singing, how doctors have found the virus outside of patients rooms (even in negative pressure spaces – which is concerning for healthcare), and how aerosoled particles are different than the bigger, respiratory particles. That webinar has a lot of the science with graphs and pictures about airborne transmission. The webinar was mainly directed to singing but can be applied to sporting events and enclosed workspaces too.

โœ… I’m also linking to another article written about being in an enclosed workspace/church/area and how to protect yourself and others. (Enclosed workspace post below in sources).
