Not sure the number of tests matters mate, it’s the % of swabs (as above) that generally gives the best indication of community transmission.
Personally I don’t trust test nos, for example the U.K. count Antigen/lateral flow tests, we don’t just PCR , we buy antigen tests in a newsagents and just bin them, they aren’t an “official” test here. So our cumlative official tests are all PCR. If we included antigen tests that figure would jump by many multiples.
There is a spectrum of reaction at the moment, a lot of early data and science saying it may be milder illness, however transmissibility is wild and the positive % rate above indicates it. We have the most excuse the pun “conservative“ Goverment in Europe in terms of restrictions shifting in their seat tonight and are concerned, I think that is telling.
My own interpretation is the big risk and fear is the surge. I think what hasn’t been said is we are in the middle of a pretty significant Delta wave, we’re slap bang in the flu season. In terms of hospital capacity we have very high numbers of services full right across the continent, a surge of omicron on top of where we are could buckle hospital services. That’s how I read the U.K. tonight shifting in their seat tonight and the biggest risk now until March. The game we’re in now is protecting society to protect health services.
