On May 12, 2020, a cosmetologist at a hair salon in Springfield, Green County, Missouri, USA, developed respiratory symptoms, and one colleague also developed similar respiratory symptoms 3 days later. The two were diagnosed with a novel coronavirus infectious disease (COVID-19) on May 20, but they continued to work until the day when the diagnosis was confirmed.
In response to this situation, state health authorities provided free new coronavirus tests to 139 people and 6 colleagues who were hospitalized after the symptoms were detected, and 67 people (48.2%) in total received the test. did. However, all test results were negative, and an interview survey with all parties was conducted two more weeks later, and no one had COVID-19 symptoms. Of the two hairdressers did not transfer COVID-19 to a total of 145 guests, 139 guests and six colleagues.”
Hairdressers are considered to be occupations with a high probability of being infected with the new coronavirus because they come close to customers, but the results of this test were unexpected. Regarding the cause of this, a report published in the Center for Disease Control and Prevention in the United States analyzes that the 'COVID-19 Measures' implemented by the hair salon where two hairdressers worked worked differently.
The hair salon, where two people worked, reduced the number of people waiting in the waiting room to 25% of the normal, widened the spacing between seats, and required both hairdressers and guests to wear face masks. .. When we actually interviewed the customer in question, out of 104 people who cooperated with the answer, 102 people (98.1%) answered that they didn't remove their masks during the haircut. Among them, 101 people (97.1%) answered that the hairdresser did not remove the mask, suggesting that ``wearing a mask'' was firmly maintained at the beauty salon. It was.
On the other hand, it was also revealed that the first hairdresser had transferred COVID-19 to four of her husband/daughter and son-in-law/roommate who live together. Regarding the difference in COVID-19 infection status between the hair salon at work and the home, the paper authors said, 'Wearing a mask to reduce the spread of the new coronavirus, especially when social distance cannot be achieved. This is the result of supporting that.' 'It's exciting news about the value of masks in combating COVID-19,' said Clay Goddard, director of the Green County Department of Health.
