I can't be sure, obviously, but I'm pretty sure I had/have Omicron.
I got it in central london within the last week and within two days everyone I saw in the office had it, and then family also have/had it.
I don't want to jinx it but it was 3 days of feeling rotten and that's it.
No usual symptoms of Covid.
Not sure if that gives hope to those of you who are/were, like me, petrified.
