Yup both 6 feet and 15 minutes are nonsense.
6 foot appear to come from late 1500s. Length of plague stick. Not joking.
15 minutes is made up. Nobody can even find the origin of that one.
It was all cognitively to support droplet, which was Chapin's guess in 1912.
A _guess_

6 feet coming from 1590. I wish I were joking. This is beyond parody.
After this was some studies in early 1900s where bacteria found within 6 feet but there were other studies that contradicted this.
After THAT was 1981 and the ridiculous baby study.

This was a contagion doctrine. Generally was time of miasma theory (disease floats everywhere over long distances).
1800s, germ theory taught us WE harbour the germs, and they knew we exhaled, but Chapin 1912 said droplet. Wells tried to say otherwise but ignored.
Then COVID.

And to complete the story this is the CLOSEST I ever found for 15 minutes and Lord have mercy on our human myth-repeating souls if this is supposed to be evidence-based pandemic response:

So, #COVIDisAirborne.
Floats. Like smoke.
Indeed all respiratory diseases are. When you do not see a lot of spread, it's because disease not as contagious as others. It is not because it is predominantly "droplets" or not.
Avoid indoors, mask, ventilate, filter.

If you want a really good, albeit sad, story, this one about Wells and Wells husband and wife team who fought their whole lives to show things were airborne, is my favourite.

Here is a list of air experts, poach it, follow it, do whatever you want. They know their stuff.

If I had to pick two on air @jljcolorado and @kprather88, for knowing history, errors, and advocacy for air matters, but lots of good names out there.

#COVIDisAirborne
Virus moves like smoke. Avoid indoor, mask, filter, ventilate.
And healthcare needs N95s and up.
