Those conditions as a killer of covid virus have existed as known in any introduction to microbiology text book printed in say 60 years....this was understood from the very first infection....the precise for strain numbers as it will apply to Covid 19 individually was the only part that was unknown...no person with even a most rudimentary introductory level understanding in biology would ever consider otherwise..also gold, silver and any other higher metal on the periodic table will...we don't have the numbers possibly but it is known absolutely they will as it is simply understood basic biological science.
No thats understood as it exits in science......
People are half wits in the main...they operate as per their most primitive portion of their brain like an old sega computer would with no wider programming for higher computation/behaviour.
This means that because people behaviour is a stratified affair across modern society more especially with very little to no higher functioning ability is available to this base...if they let people have their head a whole demographic or multi demographic of in aggregate understood people will behave in such a way as to ruin or place at risk the sacrifices made to create the current curve... for this in their nature and unchangeable for life.
Vic..actually Melb most esp is the one place where those least available to modify even basic behaviour flock toward from every other state and region.....the low caste behavioural cohorts that exist in prevalence more in that state compared to any other is like a moth to flame for these behavioural types...hence just like NY in the US where the same social understanding exists and directly resulted in their high numbers of deaths........higher operating regions and lower operating regions on the spectrum of human behaviour needs different level of management.
