Even if she doesn't get coronavirus, the fact that she's being so strictly isolated will itself take a toll on her health.

She won't be on her normal routine, going out and about. She won't be interacting with hardly anyone. She'll be stuck alone, at home, sitting around. Probably for a very long time as she was the first to isolate and will be the last out of isolation.

This in and of itself could cause a health failure.
