CHICAGO (WLS) The Centers for Disease Control and Prevention released a case report Wednesday involving a high attack rate at a Chicago gym, where infrequent mask wearing was reported.
In August of last year, during one week of a high-intensity fitness class, 55 out of 81 attendees developed COVID. Some took classes on the same day or after receiving a positive test result.
Twenty-two (40%) of people with COVID-19 attended on or after the day symptoms began, health officials said. Most attendees (76%) wore masks infrequently, including people with (84%) and without (60%) COVID-19, the CDC said.
The report reinforces public health guidance that mask wearing and staying home when ill are critical for reducing the spread of the virus.
