Most everyone I know who has kids in the school system got covid in the omicron wave. But almost all of us without children managed to avoid it. My social circle is mostly 40+ and a lot of us telecommute. I was at a table the other night with 6 people, 3 couples ranging in age from 30s to 60s, and none of us have had covid. But I also live in a highly vaccinated state, all of my friends got their boosters, and mask wearing was pretty universal during the omicron wave. And I didn't see anyone other than my husband for 5-6 weeks since I work from home and don't have to have any exposure. He did have a lot of less careful co-workers, mostly with kids, who got it.
Now that our wave has receded, our hospitals are down to August 2021 levels (which were very low here - we didn't have much of a delta wave), and our positivity rate is around 2%, I am taking advantage of the lull to resume a social life, go to the gym, restaurants, etc. I'm still wearing a mask in grocery stores because it's easy and risk is cumulative - it's not all or nothing. And I'm holding off on travel to Europe because they're still pretty omicroned up...which is curious because I thought they had omicron before we did in the US.
