With no clear direction on how to handle the COVID-19 pandemic, it’s been hard to decide what’s safe and unsafe as countries begin to open up. There’s no right answer; you just need to know the risks and how much risk you’re willing to take. The following is a consensus, compiled by Professor Saskia Popescu, an infectious disease epidemiologist at the University of Arizona, Dr. James P. Phillips, MD, the Chief of Disaster Medicine at GWU Emergency Medicine, and I, Ezekiel J. Emanuel, developed a COVID-19 Risk Index to help you do this, based on four key factors:
1) Enclosed space
2) Duration of interaction
4) Forceful exhalation
We hope this Risk Index is helpful to you as you decide what you are comfortable doing. You can tweet, post, e-mail, or print and hang this on your refrigerator or around your workplace.
