I'm interested in thoughts about the scale of NSWs outbreak.
It looks like we "may" have just peaked and be heading down the other side, with about 10% of the population having been (officially) infected. Lets double that and say its actually 20% and will get to 25% as part of this wave.
Is 25% enough to move you to an 'endemic' phase, given 75% of the population is still not affected? How did the spread of this wave stop before hitting a majority of the population? Are we going to have another similar sized wave or bigger when schools reopen?
The estimates of cases is hugely problematic.
My gut tells me the real number is much higher.
There are two types of exposure to viruses. Those who have untraceable exposure events, and those who become what we in lay terms call infected.
I am including asymptomatic cases in the infected group.
But most virologists think there is a specific exposed group that people like us and the media do not understand. Let's just call them 'exposed only' to help me explain.
Exposed only' to omicron would be someone who gets virus in the nasal passages, a very small amount, and the body kills it without anyone ever knowing. Well you can check with a blood test after the fact.
Therefore Australian blood donor samples will start revealing a good record of the true % of people exposed to Covid.
In this group you will see some level of immunity develop among those who have decent immune systems ( this is pre supposed since they killed Covid rappidly in the first place).
If you consider this principle of exposure, then the wave in NSW could be falling because as many as 75% or higher have been exposed.
Also, and more importantly, we are entering the window where people were told to put on masks. And we have seen this with every wave.
A wave comes, restrictions are minimal re masks and indoor gatherings....the wave explodes....people panic....masks go back on, people stop going to bars and restaurants, the waves go into decline.
An R Naught is a measure of human behaviour more than a function of a viruses infectiousness in terms of transmission.
NSW is lowering the R Naught.
As for endemic phases, I do not believe in it with Covid until we see years of these current waves being finally met by a world wide treatment response of the virus.
I think we can talk about endemic when Govts unite and take the patents from big pharma, and Govts fund therapies and vaccines for all...all at once.
Right now we have a new omicron going straight over the old...I keep telling people this idea of endemic living with is complete bulshit with this specific virus until there is some fundamental change at some unpredictable future point.
No one knows!
