Dozens got coronavirus from high-intensity workouts in gyms. The CDC warns that masks, better ventilation are a must. - The Washington Post

Fifty-five of the 81 people who attended high-intensity classes at the facility between Aug.

Added to this, 22 people attended the high-intensity workouts despite exhibiting covid-19 symptoms and three after having tested positive for the virus.

Yes, people brought masks but evidently [a majority] said they wore them rarely, including some attendees with covid.

Researchers traced the outbreak at the three gyms to a 37-year-old fitness instructor who, before exhibiting any symptoms, taught classes at two fitness facilities on the island.

On June 27, two days before his first symptoms began, the man taught a one-hour yoga class to 27 people.

The following day, the instructor taught a high-intensity cycling class where neither he nor the 10 participants wore masks.

The instructor, who said he was more than six feet away from class participants, stood on a pedestal as he shouted instructions and words of encouragement.

On June 29, four hours before he began exhibiting symptoms, he taught his last cycling class to a group of 10 people.

The class took place in the same room he had taught the day before and no one wore masks.

One of the participants in that class was a 46-year-old personal trainer who taught at a separate facility.
