Below is Brave Entertainment's official statement:

"Hello. This is Brave Entertainment.

Brave Girls member Yuna received positive test results for COVID-19 today.

Yuna has already completed her 2nd dose of vaccination, but due to a sudden decline in her condition, she underwent a PCR test yesterday. This morning, she received her positive test results, but Yujeong, Eunji, and other affiliated staff members who also underwent the test received negative results. However, we will do our best to prevent the spread of COVID-19 by continuing to reconfirm by using a test kit and consistently undergoing the PCR test.

Following the results, Brave Girls will halt all activities and take all necessary measures in accordance with quarantine guidelines.
We will prioritize the safety of our artists and staff, and will do our best to help our artists recover by taking all necessary preventative measures."
