The Covid advice differs depending on where you live in the UK. might not arrive in time to forestall the early, and often most potent, stages of transmission, most PCR tests do seem to be detecting Omicron well, rapid antigen tests arent a perfect solution, less able to pick up on the virus when its present at pretty low levels, vulnerable communities that need them most, taken very early in the course of illness.
