To mitigate the spread of COVID-19, official public health guidelines have recommended limits on person-to-person distance (6 feet / 2 meters), occupancy time (15 minutes), maximum occupancy (25 people), or minimum ventilation (6 air changes per hour).
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.
