Amazon is closing a warehouse in New Jersey until Dec. 26 after an increase of asymptomatic coronavirus cases was detected through the company’s in-house testing program.

An Amazon spokesperson said workers will be paid for all shifts they miss and the company is not expecting any delivery delays as a result of the temporary closure at the warehouse known as the PNE5 facility.

“Through our in-house COVID-19 testing program, we detected an increase in the number of asymptomatic positive cases at our PNE5 facility in northern New Jersey and have proactively closed the site until December 26th out of an abundance of caution,” Amazon spokeswoman  Leah Seay said in a statement Monday to The Hill.

Seay did not respond to questions about how many Amazon workers tested positive at the warehouse or whether the company is planning to temporarily shutter any other facilities.
