They will be kept on precautions and likely in Negative Air Flow rooms, which keep germs from entering the general hospital atmosphere. They may be dealing with germs from the cave that they don't know about, given that it's so rare to have this situation where they've been exposed to the cave atmosphere for so long, they just don't know. (Medics may have seen some evidence of, say, respiratory, or skin infections, as an example.) Parents will likely still be able to visit them in the rooms, but may have to wear gloves, gowns and masks, as will the staff, until diseases from the cave have been ruled out. Infectious disease practitioners are going to be kept very busy here, and challenged! (I have seen some cases over the years where they have found germs on patients and in the atmosphere they didn't even have names for, and that's just in our everyday world, not a cave!)
Yes, yesterday I saw this story about a woman who also survived being trapped in a cave in Thailand after her fiancé and fellow travelers were killed when the water rushed in. She was trapped for less than a day, and yet still had serious medical complications from whatever was in the water (Weil’s disease, a form of leptospirosis I believe?) https://www.myjoyonline.com/opinion...itish-survivor-of-past-thai-cave-disaster.php
