[Question] How does late-2022 COVID transmissibility drop over time?

This seems like the kind of thing LW folks might have good information on (better than my random googling).

I tested positive 7 days ago, and have been on Paxlovid for 5 days; symptoms are mostly gone, and we’ll see if they bounce back when I finish the course of Pax. I would like to avoid giving my wife Killian COVID, but also it would be nice to be able to help out around the house more than is possible with strict isolation. I’m considering switching to “mask around the house, but not holed up in my office all day every day.”

Anyone have a lead on good info about transmissibility during days 7-14, given positive or negative antigen tests on those days?

Thanks!
