At least 145 employees of a Washington state Costco are infected with COVID-19, health officials from the country announced Tuesday, according to a report.
The outbreak at the store in Union Gap could worsen, officials said, while testing workers continues, KOMO News reported.
“As Costco continues with the site-wide testing, we expect the number of cases to increase over the next few days as the results are received,” Melissa Sixberry, director of disease control at Yakima County, told the outlet.
The store, which employs 383 people, may remain open during the outbreak because it has implemented measures recommended by the province to limit the spread of the infection.
All 145 workers who tested positive were in isolation, the report said.
Yakima County, where the store is located, reported more than 18,200 confirmed COVID-19 cases as of Wednesday.
