The first strain has more or less totally died out here, I think, as has the Delta strain. We're being told the latest spread is a mutation of the Omicron variant. A lot of people are catching it again at the moment, but there are no longer any laws regarding isolation, masks, etc... so people can do as they please even if they've caught it. And you'll only know if you test for it, and a lot of people won't bother testing because now you have to pay for any test, even basic lateral flows. My workplace gives them out for free so I'm able to check, but for a lot of people there's no such thing.
