The recent Coronavirus epidemic has prompted Samsung to close down its Galaxy Z Flip factory in Gumi last week. It was shut for over the weekend and resumed operations shortly after. Samsung has shut it down again for an additional two days, as another employee was found carrying the virus. Production will remain suspended at its Gumi plant for two days. A plant official told a Korean news outlet:

The entire Gumi 2 business site will be closed by 7 pm on March 1 for defense, and the floor where the examiner worked will be closed for 3 days by March 3, and then resume production."
