An officer based at the ministry compound in Seoul tested positive after developing symptoms. Some 60 military personnel who came in contact with the officer, however, tested negative.

A civilian employee of an Army unit in Cheorwon, 88 kilometers north of Seoul, was infected after an acquaintance tested positive.

An officer of a unit under the direct control of the defense ministry in the southeastern city of Mungyeong was also confirmed to have contracted the virus.

An Air Force trainee stationed in a boot camp in Jinju, 434 kilometers south of Seoul, tested positive through a regular COVID-19 test.

Seven other members contracted the virus during their vacations.
