The study used data from more than 1,700 health care workers at the U-I Hospitals. Brooks Jackson, dean of the U-I College of Medicine, says workers tend to let down their guard when they leave work.
“The workplace was the lowest,” Jackson says, “and that’s not surprising, given that we have hand sanitizer, and we’ve got masks.” The data showed 26% of exposures at home turned into infections, compared to just 10% of exposures in the workplace. The study found 17% of exposures overall turned into COVID-19 infections.
Jackson says it’s clear that most workplaces will be safer. “I think when you look at an eight-hour day in the workplace during this time period,” he says, “probably 95% of the time, people have been wearing masks.”
The U-I health care workers used in the study all self-reported exposures between September and November of last year.
