Interesting to read this as well. Where a lot of staff are continually tested (e.g. NHS/teachers), infection numbers will obviously be higher than in working populations where routine testing does not take place. fullfact.org/health/teacher-covid-transmission/
We all know we can't go for elimination and so we have to live with this virus. To most people who are vaccinated, Covid will be mild (please don't jump on me, I know there are exceptions).
Kids tend to get more asymptomatic disease and so many scientists (won't reference here as mentioned in most research on the topic) will assume that someone with severe illness also shred more viral load.
So far, 24 kids have died in the UK. Sad for those involved but clearly a vanishingly low number and those kids who are admitted to hospital tend to have neurological or genetic disabilities (e.g. severe learning disabilities or Down's). This is not widely reported but I refer to a recent, very interesting study/podcast by Zoe.
Long Covid in children has also, in a new study (UCL) been found to be very rare and generally affecting older girls who already had physical or psychological problems.
Basically, we now need to get on with it, stop testing kids routinely (unless symptoms - this is what happens in most other countries), eventually stop testing altogether.
PS - I'm 55+, female with an underlying condition which meant I was supposed to shield. Did so during the first 12 weeks but once data became available (and I actively sought it out, including abroad if I wanted more granular data) I realise my risk profile is low and have since not paid any attention to the shielding list
