My partner and I were both fully boosted and both caught it in November. I'd been only been boosted for a week, her for 4 weeks. For whatever reason, her case was worse with about a week of fever, sore throat/sinuses, and all that. I never got a fever but was otherwise similar.

We'd both managed to avoid catching it at all before that, despite going on regularly and flying internationally a few times. We've just been good about masking and getting our shots.

I think this current strain must be extremely contagious. It sure was nice back when the government was tracking and reporting on this stuff.
