Samsung Electronics said on Saturday that one coronavirus case had been confirmed at its mobile device factory complex in the southeastern city of Gumi, causing a shutdown of its entire facility.

Samsung Electronics, the world’s top smartphone maker, said it plans to close the complex until the morning of Feb. 24

The company plans to complete disinfection work at the plant in Gumi, 260 kilometers southeast of Seoul, by Sunday and resume operations at the plant on Monday.

“The company has placed colleagues who came in contact with the infected employee in self-quarantine and taken steps to have them tested for possible infection,” Samsung said.

Samsung has two production lines in Gumi for some of its smartphones.

Samsung has shifted about half of its smartphone production to Vietnam but still produces some of its premium models at the Gumi complex. The Gumi plant produces Samsung's flagship smartphones, including the Galaxy Z Flip foldable smartphone.

A Samsung official said the temporary shutdown is unlikely to affect production of smartphones.
