Wow that is fast! Track and trace have just told me i likely caught it 3-7days before I got symptoms.My mum caught Covid off my son. She picked him up Saturday lunchtime (we had no idea at that point he was infected obviously). She developed her first symptoms the following evening on the Sunday. Tested positive Monday on lft. It is very fast!
Also, I've just done a quick Google and only 54% of UK cases are Omicron. I thought that would would way higher. I'd love to know which I have again, pointless but I'm curious.
