An Oakland University William Beaumont School of Medicine associate professor was part of a group of physicians who recently assessed the COVID-19 risk factors of various activities.

Matt Sims, M.D., director of Infectious Disease Research, Beaumont Health, and OUWB associate professor of Internal Medicine, was one of four tapped by MLIVE.com to assess the risk factors associated with various activities.

(The others were from McLaren Health Care, Spectrum Health, and Henry Ford Macomb.)

The team looked at five factors: inside/outside; proximity one person would be with relation to another; duration of exposure to others; likelihood of compliance with guidelines; and personal risk level.

"Until we have a vaccine, we are going to have to move forward with risk reduction strategies," Sims told MLIVE. "Because you can't keep the economy on hold forever, you can't keep peoples' lives on hold forever."

The list below assigns a score for activities ranging from 1 to 10 with 10 being the riskiest.
