@containsnuts I had the same thought this morning. I plan to continue to be cautious whilst this becomes clearer to protect the elderly and unvaccinated young ones in the family. Long term side effects of covid are also a concern and there's no reason to suppose these are removed with this variant. If deaths are lower that is fantastic but it's such early days.
Another thought is virus spreading where there maybe some immunity against severe disease (vaccination or otherwise) is not the same as virus has mutated and become practically benign. The high number of younger people infected could (as containsnuts says) skew data, as risk of under 50s dying or in ICU is tiny with previous variants.
What about infants/immune compromised and other groups, especially given the transmissibility of this variant, we don't want these ones to find out the hard way.
Finally just the high transmissibility is a worry for our busy flu season, it could quickly disable services with absences; including healthcare environments already struggling.
Erring on the side of caution utilising every practicable mitigation is surely wise. Personally we are upgrading masks and testing more. I'm rather hoping DH will look at ventilation in his work environment (nhs, so he will be working throughout).
