I do not believe there are medical teams evolved.

It is open to the public and anyone can come observe the person's healing ....People are very private.....
Yes, people are so "very private" about their medical conditions that they go to an event that "is open to the public and anyone can come observe the person's healing". Yes, very private indeed.
