I know this is a bit of a hypothetical question but I'm driving myself mad waiting to catch Covid. Husband tested positive last Thursday but had been having symptoms since last Monday. He's still ill with it. Assume it's Omicron but don't know. Had it confirmed by PCR. I've been sleeping in a separate room since he tested positive but we have been spending time in the same room, although distanced. I'm still testing negative. I think I would have caught it by now if I was going to?? Neither of us have had Covid before.
