(NEXSTAR) – A new report from the Centers for Disease Control and Prevention suggests that some indoor exercise facilities may have trouble preventing the spread of COVID-19 among exercisers.
The report studied a single Chicago gym in August 2020 and found that out of 81 attendees of indoor high-intensity classes, 55 people fell sick with COVID-19 — or 68 percent.
Twenty-two of those infected attended classes on or after the day symptoms began, and most attendees (76 percent) wore masks infrequently, including persons with (84 percent) and without COVID-19 (60 percent).
The gym appeared to be following most public health protocols. All classes were held at 25 percent capacity or less, and mask use, temperature checks and symptom screenings were required on entry. Exercisers were stationed six feet apart and brought their own equipment.
Here’s the catch: Patrons were allowed to remove masks during exercise.
