"Hello, this is KQ Entertainment.

We would like to notify that ATEEZ member San has tested positive for COVID-19 while asymptomatic. 

ATEEZ members Yunho, San, Mingi, and Wooyoung recently returned to Korea as a part of the early team after wrapping up the group's world tour stops in the U.S, and prior to their scheduled departure, all of the members tested negative in their PCR tests before arriving in Korea on February 12. 

Per current disease prevention guidelines, the members underwent an additional PCR test after their arrival, and on the afternoon of February 14, member San's test results returned positive. Members Yunho, Mingi, and Wooyoung's test results returned negative, and they are currently in self-quarantine per instructions from healthcare authorities.

All members of ATEEZ have completed their second doses of the COVID-19 vaccine, and San is currently not showing any symptoms. 

We apologize to the fans for causing concerns, and ensure that we will do our best for San's speedy recovery.

Thank you."

Get well soon, San!
