A new model to predict the exposure risk of COVID-19 has been developed by professors at MIT.
The model takes into account risk factors like the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates.
This can allow policymakers, businesses, schools, and individuals to gauge their own risk.
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.
