Interesting, but I don't think the bacteria are mutating the same way as the virus. Check out the genomic map on page 6 of the link below, I had assumed that each variant was based on its preceding variant, but apparently that is not correct, omicrons roots are from the original strain.
Suppose the most successful viruses are massively contagious without harming (much) the host, lest successful kill the host before jumping to a new one. Seems common sense, ...
... however goes wrong with a bit of gain of function tinkering by dr frankenfucky.
I hope you're right but it still feels like a lot of wishful thinking pushed by people who so often seem to enjoy hearing their voices on TV more than they enjoy being right.
As far as I can tell evolutionary forces gives the virus 3 main objectives #1 evolve to evade immunities in the community #2 if at all possible try to become as infective as possible prior to being detected, and #3 make sure you don't kill the host off prior to replicating and infecting at least 3-7 others so as to hit an exponential reproduction cycle.
If you don't believe me look at the AIDS virus that thing never got less deadly with time and was perfectly happy killing off the host. Good thing that one didn't spread thru airborne transmission or I bet humanity would look quite different.
Seems like the whole level of severity and how the virus effects the host is just a luck of the draw type of thing. Assuming the virus doesn't kill the host too quickly - how we feel after our infection is of little concern to the virus.
Bacteria =/= viruses.
Did smallpox become less virulent over time?
Nope. it was vaccinated out of existence.

I just downloaded the article, and will read it. But I notice two things:
1. The authors all live and work in China, and so they are by definition interested parties.
2. In Figure 3, the ellipses for Bat and Dog are similar, and are perpendicular to that of Mouse. But mice and bats are closer genetically than either is to dog, so I'm perplexed. Also, there may be some other animals that get COVID or related viruses, such as the Pangolin, which isn't listed.
Bat, pangolin, humanised mice, hardly probable in nature at a guess however the biolonutters seemed rather determined to get the bat bug into humans at all costs ( can be calculated in millions I suppose) the argument of preventing a pandemic by GOF research seems bit backwards, the CCP are hardly the right folk to trust with WMDs just because it was made illegal to carry out this kind of research in the US and Europe, even trusting them, building a L4 lab ( thanks to mr Jean Claude Barnier and Mr macron) seems foolhardy at the extreme, our leaders were and are complacent it the destruction of our economy, freedom and way of life.
Should we continue to trust them, I think not sociopathic megalomaniac with a touch of psychopath seems probable
First my answer: no idea.A question I have for Joe Gwinn, perhaps Denis too.
I had Covid june/july last year. While I had symptoms id test myself most days with lateral flow tests to see when the viral load was on the decline. Out of curiosity I thought to attempt to test breath condensate. Using clean glass I collected samples from normal and heavy breathing, swabbing and testing the condensate yielded negative results despite me still testing strongly positive using the normal procedure.
Any ideas as how meaningful this result is? Ive read papers that suggest either way that covid is/isn't in tidal breath.
#1. It has been peer reviewed, and I'm pretty sure the Chinese know more about this than anyone else
#2. It appears to me (not a scientist) that a lot of what is talked about in that paper is still hypothetical and needs more research.
First my answer: no idea.
Comment: You tried an interesting experiment that seems relevant to transmission concerns. Good on you! But you need more test kits and glasses—-first just breathe on the glass for a period of time, then sing a medium-pitched note onto the glass, hold the glass at various distances etc. Of course, I am being facetious. But, speaking vs quiet breathing has been shown to cause much more droplet spread/transmission. (As a side note, my wife had been a member of the singing group in Skagit County where one of the early outbreaks occurred).
Hopefully, someone with some actual knowledge (that’s not me) can answer your question.
Like you, I did briefly search on aerosol transmission of Covid/SARS. There are lots of interesting studies.
