I went to the find a grave site and found this entry. It seems to be real enough. It says she died in Tennessee 15 Dec 2020. In the video of her fainting, she wore a mask but the eyes were the same and her name tag said Dover. The Hospital was CHI Memorial which is located in Chattanooga, Tennessee.
So, this is her and she died. https://www.findagrave.com/memorial/232915568/tiffany-dover
