So my point on that, is this isolation necessary if the virus simply does not result in hospitilisations anymore?
While there does seem to be some thought that the virus is possibly now more transmissible, but less deadly, there does not seem to be anything conclusive on this yet.
What we do know however is that it currently it does still cause hospitalisations, ongoing health issues for some of those infected, and death. So while in time CV19 may become a lot less deadly, it is not yet there.
When the Second Wave gained momentum in Victoria what also happened was that the % of elderly who were getting infected dramatically increased and hence hospitalisations and the rising death toll followed. I have not seen the active cases by age profile metric for some time now, but presumably the % of the elderly being infected with Covid 19 is dropping. Certainly the numbers will be.
Also with the reduced mortality rate, note that it is now known how to better treat Covid 19 patients, with better/more treatments, and that if systems are not as overwhelmed that better care occurs at an earlier time. I know that one NY Doctor made the comment at the height of their deaths that many patients were simply arriving at the hospital too late.
The goal was always stated to be to flatten the curve so that we didnt overwhelm the hospitals. That didnt even happen in Victoria at its worst.
While true, this was with various measures/restrictions in place. But it is also true that it was approaching being overwhelmed. Without restrictions it probably would have been overwhelmed.
And yes also some of the hospitalisations were due to aged care patients being accommodated as some aged care facilities had failed and could no longer service their residents. But without restrictions even more of the aged care facilities would have become overwhelmed as well which would have then also worsened the hospital situation.
