There is now powerful observational evidence that outdoor air is extraordinary safe regarding COVID-19, and the recent protests have helped provide it. The protests/riots began in Seattle and other cities on May 26th. Thousands gathered without social distancing and a good 10% had no masks. They participated in chanting, singing, screaming and other activities that ensured plenty of droplets were injected in the air, and that unhealthful environment was "enhanced" by coughing from tear gas and other agents.
Did this huge exposure result in increased spread of COVID-19? The answer is clearly no.
Consider Washington's King County, a hotbed of protests starting 26 May (see below). Both hospitalizations and deaths showed no upward spike after the protests (the blue line shows May 26th). We should have seen a signal by now, since the average time to symptoms is approximately five days.
It is important to note that the number of COVID-19 cases is going up modestly in King County, but that is being driven by a near doubling of tests (note that the bottom graph starts earlier). Much of the media neglects to note the importance of increased testing in finding more cases.
This lack of a coronavirus spike has been noted in every major city in the U.S., something discussed in the Seattle Times today and in many media outlets.
These are huge number of independent experiments in varying environments and climates. A very good sample. And the obvious conclusion is that COVID-19 has a very difficult time spreading in outdoor air. There is no other explanation.
Some of you might argue that many of the protestors were young and so would not get very ill. True enough. But young people can get sick from it and they could certainly give it to their parents, neighbors, and folks in food stores and restaurants. There were plenty of teenagers and folks in their early 20s still living at home who were at the protests.
You want more evidence? No problem. About a month ago, there was a huge media commotion about "irresponsible" outdoor parties at Missouri's Lake of the Ozarks. Several media outlets promised a huge uptick in COVID-19 cases.
What actually happened? Nothing. No spike of COVID-19 cases in the neighboring counties. Outdoor air is safe.
