It seems to be fairly infectious. I very much doubt any of the figures of infections are including those with no symptoms because who would know?

What I suspect ( gut feeling, not a virologist ) is it's something that is clearly pretty infectious, for the vast majority there are no symptoms or are very, very mild symptoms. Wife has a compromised immune system, she had a virus back in December. The symptoms were pretty much those attributed to covid-19. Didn't require hospitalisation thankfully. Now, we've not been abroad last year, not been in contact with people who have - so if she picked it up then would have been heavily present in UK back in December.
