My friend had a positive Covid test ten days ago and her isolation ends on Sunday. She hasn't been very ill at all but many of her colleagues who also tested positive have been. Her main symptoms are a cough and a loss of taste and smell.
She is due to come and stay with me for Christmas on the 23rd.
I'm worried she will still be contagious. I know that science decrees she won't be, but how do they really know? Don't people continue to shed viruses for a while, even after they have recovered?
I can't cancel her as she is my oldest friend and has no one else to spend Christmas with, but I am secretly kind of dreading it as I know I will be worrying about it.
Is there any way I can be sure she's no longer contagious?
