Even if she doesn't have symptoms, she should get examined. I understand the stigma that can come from this illness but her health is most important

Explanation: Patient #85 (in seoul) #3684 (in korea); diagnosed on Feb. 29th; female; born in 1988; residing in Gangnam-gu; recently traveled to Italy; currently in quarantine at the National Medical Center.

On Seoul's city website you can see each person who has tested positive in the city, including where they are located and for many of them, they also include a recent history of movements. I'm guess the above is one of the staff members~

Also, to get tested if you have no symptoms is a waste of resources that are much more needed elsewhere, to be honest. Just self-isolate for the 2 weeks and keep track of anyone you may have been in contact with.
