Teenagers are immortal.

COVID killed my mom. She was in assisted living and confined to her room. She had lost her cognitive ability to read a book and follow the story. She used to be a voracious reader. She lost her cognitive ability to watch a TV show. She died from boredom and loneliness. I saw her 3x a week for an hour, although I always cheated and stayed longer. I retired and got her home with me but she died within hours.

In other words, the actual virus isn't always the killer. The repercussions and evil nature of it is the killer.
