Indoor safety is crucial to curtailing the spread of the SARS-CoV-2 virus. How can we protect ourselves in a closed environment? How do we ensure safety in our homes, schools, and other indoor public spaces? The online tool created by John W. Bush, Martin Bazant, and Kasim Khan captures the realities of the infectious potential of COVID-19 in indoor spaces. The COVID-19 Indoor Safety Guidelines tool allows a user to tinker with the controls: you can choose the room specifications, the number of people, the kind of activity. Once the information is plugged in, the system tells you how many hours it would take for people to get infected, provided there is one positive case of COVID-19 in the room.
This tool brings data, computing, and research into a user-friendly and comprehensible format, keeping us better informed about the risk of infection in these uncertain times.
