MIT researchers have built a simple tool to give clear guidelines on indoor safety in the midst of a pandemic.
Quote:
So are any of us safe indoors during the COVID-19 era? Can we go to a grocery store? Can we meet with a loved one? Bush, alongside his MIT colleague Martin Z. Bazant, have answered that question with a complex mathematical model, which simulates the fluid dynamics of virus-loaded respiratory droplets in any space, from a cozy kitchen to a gigantic concert hall.
And because the equation is far too complicated for most people to understand, they turned their findings into a free online tool. Go to this website, and you can create your own custom scenario to judge COVID-19 risks for yourself.
This answers a lot of questions that have been posted here for the past 9 months
Note that the six-foot or two-meter distancing guideline would indicate that up to 2 people would be safe in this room for an indefinite period.
I'm concerned about an indoor situation in which the two people would have to be closer than six feet because one of them is a doctor treating the other. Specifically, a dermatologist doing a skin check on a patient. That procedure could easily take more than 15 minutes.
...be sure to look at the "human behavior" tab - it defaults to people being at rest, only whispering, and wearing masks...so going to a fitness class with no masks would make a big difference, e.g.

Yeah, I didn't see "hospital room" on there. What if you are in one for a few days with masked staff bustling in and out and getting up close and personal... but only a minute or so each time....
Is that chart assuming everyone is masked, or not?

Under the Human Behavior tab, you can set whatever kind of mask you want or none at all. Everything from None (Face Shield) with efficiency of 0% to N95 Respirator with efficiency of 95%.
I don't see any setting for the cheap procedure masks so many people wear, fooling themselves into thinking they're surgical masks and therefore offer some protection.
Remember that the prison guard who got COVID from very short exposures to six inmates he was processing for intake was only wearing a microfiber mask, not a respirator. And for part of the time he was interacting with the inmates, they weren't wearing masks (nor were they required to). It turned out he had had 17 minutes of cumulative exposure during one day and all six of the inmates were infected.

Boeing 737 - interesting, and rhymes with previous data.
Most domestic flights aren't a huge vector of transmission.
Amazing isn't it that flights are happening everyday, no shutdowns. Huh. I guess COVID is afraid of flying?
