A cheap model for Pandemics and the place of Viruses in general

Mortality from the 1918 pandemic and 2019 pandemic aligned so peaks match.

1918 had no medical intervention while 2019 had vaccines before the 3rd wave.

Mutation rate for SARS2 = 3.7E-6 and FluA 1.5E−5 that is FluA evolves 4 x faster than SARS2. The peak Wave Length for SARS2 = 9 months and FluA = 4 so 2.25. I needed to stretch the 1918 graph by 2.25 to make it fit. Not sure exactly how to relate rates and wave lengths but they are comparable.

So what have we learned:

(1) Viral mortality is caused by poorly coevolved parasite and host. As pandemics progress mortality falls.

(2) Peaks are caused by new variants, rising as variants take over from previous less well adapted variants and falling as host immune systems adapt

(3) Pandemics are short lived taking around 3 significant variants and peaks until the parasite has evolved to coexist with the host. Coronavirus evolves much slower than influenza so the 2019 pandemic took longer than 1918.

(4) Hosts exist in an interdependent "viral ecology" and depend upon viruses for their health. It is wrong to think that viruses are the enemy and cause illness, they also cure it. If we remove viruses we create a blank slate for poorly evolved lethal viruses to take over. Omicron is now protecting us from a whole range of transspecies cross over "bat-flus".

Hypothesis: The above presents the mechanism and pattern of a typical pandemic.

Its a shame that no "experts" have put anything as comprehensive as this forward, or shown any real understanding of the pandemic.
