YAKIMA, Wash. – A coronavirus outbreak at a Costco store in Yakima County has infected 145 employees, and health officials say the rapid increase in cases at the store is similar to a “superspreader event” in which multiple people are infected at the same time.
The findings were released Tuesday by the Yakima County Health District after store-wide testing at the Costco in Union Gap.
All 145 employees that have tested positive are in isolation or quarantine, but the store itself remains open, officials said. The store employs a total of 383 people.
