No cases of coronavirus have been linked to two Missouri hairstylists who saw 140 clients last month while symptomatic, county health officials said.
Both stylists worked at the same Great Clips location in Springfield, according to a CNN report.
The clients and the stylists all wore face coverings, and the salon had set up other measures such as social distancing of chairs and staggered appointments, the Springfield-Greene County Health Department said this week.
Of the 140 clients and seven co-workers potentially exposed, 46 took tests that came back negative. All the others were quarantined for the duration of the coronavirus incubation period. The 14-day incubation period has now passed with no coronavirus cases linked to the salon beyond the two stylists, county health officials said.
During the quarantine, those who did not get tested got a call twice a day from health officials asking whether they had symptoms related to Covid-19, said Kathryn Wall, a spokeswoman for the Springfield-Green County Health Department.
"This is exciting news about the value of masking to prevent Covid-19," said Clay Goddard, the county's director of health.
"We are studying more closely the details of these exposures, including what types of face coverings were worn and what other precautions were taken to lead to this encouraging result."
