A company spokesperson told The Pantagraph that 31 Rivian employees and 61 contract workers, who are largely hired for construction projects and not affiliated directly with the company, have tested positive for the virus since the week of March 25.
The 31 positive cases from Rivian employees came from a batch of about 7,000 tests run through the Illinois State University lab, which uses rapid, saliva-based testing.
Rivian spokesman Zach Dietmeier said the number was not huge, but also "not insignificant." The company isn't considering the number of cases an outbreak, since the plant was segmented into different areas early on to "identify and contain something like this," and the cases originated from separate areas, he said.
Rivian employees who test positive for the virus are required to quarantine for 10 days and can return to work after three days without symptoms, he said.
