Apple said the new closures affect seven U.S. locations and one in Canada. They are located in the Miami area, Atlanta, Houston, Ohio, New Hampshire and Montreal, Canada.
It wasn't immediately known how long the stores will remain closed or how many COVID-19 cases prompted the move.

"We regularly monitor conditions, and we will adjust our health measures to support the well-being of customers and employees," the company said, according to Bloomberg. "We remain committed to a comprehensive approach for our teams that combines regular testing with daily health checks, employee and customer masking, deep cleaning and paid sick leave."
The closures coincide with the quick spread of the Omicron coronavirus variant. U.S. officials said earlier this week that about three-quarters of all new infections were due to Omicron.
Amid the Omicron spread, Apple reinstated a mask mandate in all U.S. stores.
