Among the people who tested positive, 22 of them attended multiple classes on or after exhibiting symptoms, and three attended even after having tested positive for the virus. The study focused on 81 people who exercised at the gym facility. The outbreak at a third was tied to another student, who also taught classes. In Chicago, 55 of the 81 people who attended high-intensity classes at a gym between Aug. 24 and Sept. 1 tested positive for COVID-19. The volunteers, made up of healthy individuals with an average age of 40, did three rounds of exercise.
Among the people who tested positive 72 of them attend effectively one class on or after exhibits.
