Indeed Australia, there were slightly more than 21,000 cases of laboratory confirmed influenza this year, as of August 23. Last year in the same time period there were more than 247,000. The uptake of the Flu vaccine was also at record levels as well as social distancing measures
New Zealand have had almost none.

Whilst the exceptionally low figures have been achieved by lockdowns, this does raise the issue, though of why we have not controlled Flu better in the past with relatively simple cross infection control measures (including masks) to protect the vulnerable in care homes and hospitals etc. The answer as ever is cost. Had this been the case, then we would have been better equipped to deal with Covid instead of scrambling to catch up with PPE.
I would suggest, Covid aside. our protocols for dealing with respiratory viruses may change forever? If there are considerably less hospital admissions and deaths from Flu and assuming Covid is controlled, it is going to be very difficult to revert to how we were from a medico legal standpoint alone.
Interesting points Doc, I know to begin with the UK Govt didn't adopt face masks saying there was no evidence of them being effective but then did a U-Turn which is previously unheard of

I believe the rationale they then adopted was that they didn't protect the wearer from contracting CV19 but they did protect other people from the wearer.
Not sure how that logic stacks up and i'm still not convinced of how effective the masks actually are but perhaps it's more important as a conscious reminder of the need to wash hands; distance etc etc and to maintain peoples focus

In terms of cost and I mean overall cost the wearing of PPE is an initial cost but then if there are less hospital cases from CV19; Flu et al then on the face of it it should be a cost saving.
However when you then factor in that people who didn't die of CV19 and flu may well then need all sorts of treatment in the extra years they live along with drawing pensions etc then wearing masks then becomes double expensive.
I'm not saying we should just let people contract illnesses and die however the harsh but true reality is that mankind is trying to find a way to cheat nature here and while we can extend the game a little ultimately nature always wins, basically the bitch has fixed it
