Calling himself "frustrated" and "disappointed", Springfield-Greene County Health Department Director Clay Goddard said at a press conference Friday that he needed to notify the public to potential community exposure.
The announcement comes as barbers and salon operators and their customers across the USA fight to reopen during the COVID-19 pandemic. At the time, businesses such as barbershops and hair salons were allowed to operate in the state.
"For a stylist to be out of work for so long and be excited to come back to work, you would think you'd want to be safe, and you don't want to be shut down again", Lilley said.
Officials say that the hair stylist had 84 clients during the eight days, and potentially exposed another seven coworkers.
"We hope that this is an overly cautious approach as, thankfully, both our case and all of the clients of our case were wearing masks during their haircuts", Goddard said, praising Great Clips for stringent safety requirements, including making everyone wear facial coverings. The condition of the stylist, who was not identified, was not revealed.
But he cautioned about the risks of overwhelming resources. The hairstylist also visited a Dairy Queen, Walmart and fitness center, officials said.
They urged those who may have gone to those places to be on the lookout for coronavirus symptoms.
"The well-being of Great Clips customers and stylists in the salon is our top priority and proper sanitization has always been an important cosmetology industry practice for Great Clips salons", they said.
"We can't make this a regular habit or our capability as a community will be strained and we will have to re-evaluate what things look like going forward", he said.
