In September, a Chicago resident called their gym with alarming news: They’d recently come to an indoor workout class despite feeling sick and then later tested positive for the coronavirus.
The gym quickly shut its doors, but it was too late. Fifty-five of the 81 people who attended high-intensity classes at the facility between Aug. 24 and Sept. 1 would eventually test positive. A similar case tied to three gyms in Honolulu over the summer resulted in 22 total infections.
Citing both cases, the Centers for Disease Control and Prevention on Wednesday urged gym users to wear masks during intense workouts — even when socially distanced — and asked gyms to improve ventilation and push for outdoor activities when possible.
