At least 145 employees at a Washington state Costco have been infected with COVID-19, county health officials announced on Tuesday, according to a report.
The outbreak at the store in Union Gap could worsen, officials said, as workers’ tests continue, KOMO said.
“As Costco continues its testing across the site, we anticipate that the number of cases will continue to increase over the next few days as results are received,” said Melissa Sixberry, director of disease control for Yakima County.
The store, which employs 383 people, may remain open during the outbreak, as it has implemented measures recommended by the municipality to curb the spread of contagion.
All 145 workers with a positive test are isolated, the report said.
Yakima County, where the store is located, reported more than 18,200 COVID-19 cases confirmed on Wednesday.
