A hairstylist with coronavirus worked for eight days this month while symptomatic, exposing as many as 91 customers and coworkers in Missouri, health officials said.

The Springfield-Greene Health Department announced Saturday that a second hairstylist tested positive for coronavirus, and may have exposed 56 clients at the same Great Clips salon.

A day earlier, officials had said another hairstylist with coronavirus at the same salon potentially exposed 84 customers and seven coworkers.

Both stylists had symptoms while at work, officials said. They did not provide details on their conditions or when they tested positive.

The case highlights the threats of community spread in the United States as businesses reopen after weeks of restrictions to combat the spread of coronavirus.

The stylists and clients wore face coverings

Both stylists worked from the second week of May to Wednesday. The clients and the stylists all wore face coverings, the Health Department said. At the time, businesses like barbershops and hair salons were allowed to operate in the state.

“It is the hope of the department that because face coverings were worn throughout this exposure timeline, no additional cases will result,” it added.

Health officials are reaching out to all the people who were exposed and offering them testing. They urged them to be on the lookout for symptoms.

Goddard did not provide details on the identity or the condition of the stylist. He said health officials have reached out to the people who were exposed, adding that the hairstylist had kept impeccable records that made contact tracing possible.

But he cautioned about the risks of overwhelming resources.

“I’m gong to be honest with you: We can’t have many more of these,” he said at a news conference. “We can’t make this a regular habit or our capabilities as a community will be strained.”

Goddard said he was pleased with the deep cleaning measures taken by Great Clips, adding that he now considers the business safe.

In a statement, Great Clips said it welcomed the results.

More than 96,000 people have died from coronavirus in the United States, where the number of confirmed cases is over 1.6 million, according to Johns Hopkins. Missouri has nearly 12,000 cases of infections and more than 600 deaths.
