Yes it can. What I will say about Covid is that is actually nothing like a cold. You have some of the classic symptoms but without that distinctive cold feeling, but also everyone you speak to has different symptoms. My brother had a terrible sore throat, I didn’t. It’s is a very strange virus indeed. But anyway I digress lol.
I actually spent the Saturday night before I tested positive having a sit down meal with my family. None of them caught it off me, neither did any of my work colleagues who I’d spent the previous week with. Just because Charles spent time with his mother doesn’t mean she will have caught it.
