A new approach to estimate the risks of exposure to COVID-19 under different indoor settings
Two MIT professors have proposed a new approach to estimating the risks of exposure to Covid-19 under different indoor settings.
The guideline they developed suggests a limit for exposure time, based on the number of people, the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates. Their model offers a detailed, physics-based guideline for policymakers, businesses, schools, and individuals trying to gauge their own risks.
The guideline, appearing this week in the journal
PNAS, was developed by Martin .Z. Bazant, professor of chemical engineering and applied mathematics, and John W. M. Bush, professor of applied mathematics. They stress that one key feature of their model, which has received less attention in existing public-health policies, is providing a specific limit for the amount of time a person spends in a given setting.

As vaccination rates continue to go up and indoor events resume, a new online tool can help calculate the risk of coronavirus.
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.
You can add in factors like amount of people, mask wearing, how long you stay and more to the calculation.
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.
