The initial symptoms of the Delta variant are like a cold - whereas with the original one, runny nose was not recognised as a symptom. They really need to update the criteria for getting a PCR test to reflect the change. However, in a minority of cases, it doesn’t stay like a cold - that’s why we have to respond,
As for why we are extending restrictions even though numbers of deaths are not rising - well, for once, we are actually thinking ahead.
Number of cases have risen 64% week on week. Number of hospitalisations and deaths have started to rise as well, although from very low levels. We are not increasing restrictions, in fact there is still some easing with weddings and wakes…. So in a few weeks’ time, numbers of cases will have doubled and doubled again… and hospitalisations and deaths will follow.
Eventually, vaccines will bring it under control. But make no mistake on 19th July, there will be more hospitalisations and deaths than there are today. That’s not me saying that - Chris Whitty said it in the conference. My assumption is he could have said “but by then we will have passed the peak and they will be coming down again.”
