When 2 hairstylists infected with COVID-19 cut hair at a Great Clips salon in Springfield, Missouri it became the “outbreak that never happened”. It seemed like the stuff of a quarantine nightmare. The hair stylists started feeling ill just one day after returning to work at their salon. They ended up testing positive for COVID-19—but not until they had already given haircuts to 140 clients. Public health officials in Springfield braced for the worst as all those who’d had appointments with the two Great Clips stylists went to get tested. When the results came back, they were shocked—and relieved—to find that not one of the salon customers had tested positive. How did things turn out so well? One reason might be that all employees and patrons at the hair salon were required to wear masks.
