Yes @hvert the guidance for household contacts recommends wearing a mask indoors, and avoiding crowded indoor spaces and vulnerable people. Like yourself I really had to hunt out that information and I suspect most people have no idea about it.

Our info states that infection can incubate 10 days from exposure, okay that must be based on some evidence but in the real world I’ve never come across that personally. It seems like a few days with omicron at least.

I can see your dilemma, can you take a rapid test beforehand to reassure yourself?
