A Covid-19 outbreak of 23 cases has been reported at the Walmart Distribution Center in Umatilla County, Oregon, according to a news release from the state's Health Authority.
Included in the outbreak case count are household members and other close contacts of an employee, the release said.
The investigation of the outbreak started on June 30, but was below the threshold needed for public disclosure.
State and county public health officials are working together “to address the outbreak and protect the health of workers,” the release said.
Walmart started requiring all shoppers to wear a face covering on Monday.
