THURSDAY, February 25, 2021 (Healthday News) – If you think you can safely Exercise During the gym without your mask Universal epidemic, Two new government reports suggest that you are mistaken.

Coronavirus Outbreak of Health Last summer the centers in Chicago and Honolulu were the result of exercisers and trainers not wearing masks, researchers at the US Center for Disease Control and Prevention discovered.

In a Chicago study, 60% of people who attended in-person fitness classes at a facility between August 24 and September 1, 2020, tested positive for COVID-19, while another 7% reported having the disease Symptoms reported. Although some infection prevention measures were taken, such as temperature checks and symptom checks upon admission, exercisers were allowed to remove their masks when they were sweating and stressed.

“It’s very important for people who want to attend the gym and what the COVID symptoms are, and to know that you’re feeling something and feeling like the COVID-19 symptom, Has to be sensitized to stay at home. As a precaution, “said Richard Terran, a CDC epidemiologist in Chicago, who co-authored the Chicago case study.

“this the outbreak Combined COVID-19 reinforces the need for prevention strategies, including the use of universal masks in public settings when individuals are with others who do not live in the same household, especially indoors; Symptomatic individuals and those exposed have been tested Sars-OKV-2; Self-Secluded Symptom onset or after positive COVID-19 test result; The report states that quarantine of persons exposed to SARS-CoV-2.

In the Honolulu study, 21 cases were linked to a fitness instructor who tested positive for COVID-19 on 1 July. Two days before experiencing the symptoms, the fitness instructor led a yoga class for 27 people wearing masks and none of those participants reported. But the same instructor did not wear a mask while leading a cycling class for several hours before experiencing symptoms. All 10 people in the class, none of whom wore masks, subsequently tested positive for COVID-19. One of them was a fitness instructor from another facility. The CDC report states that he became seriously ill and was placed in the intensive care unit.

Twelve hours before the second instructor experienced the symptoms, he held several short kickboxing sessions and a personal training session. Of the 11 exposed, 10 tested positive in early July. All 10 developed COVID-19 symptoms, and one was placed in the intensive care unit. The CDC report states that on July 22, emergency orders requiring face coverings were passed at fitness centers in the city of Honolulu.


“Not wearing a face mask, extended close contact, and poor room ventilation was likely to facilitate transmission. The SARS-CoV-2 transmission occurred despite a 6-foot gap despite steady cycles. Instructor A1 stabilized 1-hour Cycling can yell in the classroom. Has contributed to broadcasting, loudly correlated aerosol emissions during speech, and COVID-19 rapid physical activity and singing-related outbreaks have been previously reported. ” Laura Groves, and colleagues at the Hawaii Department of Health and the CDC COVID-19 Response Team, reported in their report.

Both case studies were published online at the CDC on 24 January Morbidity and Mortality Weekly Report.

The outbreaks described in the CDC studies were caused by inconsistent mask use and other flaws in socially abusive behavior, and perhaps buildings that were insufficiently ventilated, by Alex Larkom, senior manager of health promotion and health policy for the International Health Racquet and Sportsclub Association. Told the new York Times.

“In Chicago, you had members who would go to class when they were symptomatic or COVID positive,” Larkom said. In addition, that facility was not originally designed as a fitness center, and screening for symptoms appeared poor, she said.

“Society-wide, we are counting on people who are ill or think they are sick to distance themselves from society,” Larcom told times. Those who went to the gym despite the symptoms were “probably also going to the grocery store, going out to eat and moving through the community.”

Larkom said that since the summer, many health and fitness clubs have implemented new safety protocols and improved ventilation in their facilities.

CDC researchers stressed that fitness facilities need a good strategy, including good ventilation, consistent and correct mask use, constantly reminding employees and patrons to stay home when they are ill, and more hand-washing stations. Huh.
