(CNN) No cases of coronavirus have been linked to two Missouri hairstylists who saw 140 clients last month while symptomatic, county health officials said. 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. "This is exciting news about the value of masking to prevent Covid-19," said Clay Goddard, the county's director of health.
