Cool COVID model - how long can you stay in a room?

“This app, developed by Kasim Khan in collaboration with Martin Z. Bazant and John W. M. Bush, uses a theoretical model to calculate safe exposure times and occupancy levels for indoor spaces. By adjusting room specifications, ventilation and filtration rates, face-mask usage, respiratory activities, and risk tolerance (in the other tabs), you can see how to mitigate indoor COVID-19 transmission in different indoor spaces.”

Not really an app; you can go to the website I have link below. The assume is that ONE person in the room has COVID.

Lots of fun things to play around with. Room size, number of people, type of ventilation, mask wearing, etc

But you cannot change the number of people who have COVID. Default is set at one.

Fascinating. I don't pretend to know how good/accurate that model is, but it's fun to play with parameters.

A 400sf room with no one wearing masks and residential ventilation is good for about 40 minutes for 3 people.

I sent that link to D2. She comments:

Don’t need to play it, I am living it!

I'm sure it is well-intentioned but I doubt the app will enlighten anyone who is 'not living in fear'.
