An Apple Store employee, who went on leave earlier this month to care for a relative, has tested positive for COVID-19.

Apple and the employee from the Third Street Promenade store in Santa Monica learned of the positive test late Thursday, according to reports. The employee has not been back to the store since taking leave on March 2.

Apple will close all its offices, 42 retail stores and contact centers across the Chinese mainland through February 9 as the outbreak of the new coronavirus has sickened more than 14,500 and killed more than 300 people.

Apple is bracing itself against a growing coronavirus outbreak, restricting business travel to China and closing one Apple Store as health officials try to contain the deadly virus.

Apple is also trying to gauge the potential disruption to production. Most of the world’s iPhones, as well as other devices, are assembled in China with components coming from a network of nearly 400 suppliers.
