The medieval mythical miasma concept turns out to be real, no longer obsolete:

I don't use Chrome because I don't trust Google. Firefox reader mode
doesn't get around paywalls, but it does often get rid of nag overlays
like that.

How the devil have I missed reader mode until now?!

AdBlock is wonderful too; given google is an advert machine,
will ever be a Chrome equivalent?

NoScript is useful as well, /provided/ you are prepared
to to some easy tweaking to get some sites working. If
nothing else it demonstrates how many sites sell you
to many different tracking outfits.

Both speed up page rendering times noticeably, particularly
pages where your eyeballs are auctioned off in real time.

Evolutionarily(sp) speaking this is expected. It's our first interaction
with the virus and it should evolve to be less deadly and more contagious...
That's how it gets more of its 'offspring' into the next generation.

The YesScript2 add-on is great. If allows partial or full script

Until they detect your use of the adblock and block you from the web site. I get that on a regular basis. Then I switch to another browser if I really want to see it.

The Washington Post detection of adblock is easy to get around. Go to reader view which they seem to also know and cut the text short... until you reload and get the full article.

Only the aspects that result in better propagation. In the present situation I don't think lethality limits the propagation as it might with many other diseases. If it results in a less severe infection so people are more willing to suffer it and not be isolated and/or treated, that will be a selection criteria. The disease is not transmitted very well in the hospital. So in our present system it is not requiring care that gets more propagation, not so much whether you ultimately survive or not.

That is only true if the virus is so lethal that it tends to kill almost
everyone it infects before they have a chance to pass it on.

This one already produces 80% asymptomatic carriers and only kills about
3% of mostly the elderly and infirm. It is already close to optimal. It
could just as easily evolve to kill 10% or more so long as it has an
even higher R0 - and we are inadvertently selecting for maximum R0.

We have added the constraint of lockdown which is causing the original
wild form to die out and be replaced by the mutant strain with the
highest possible infectivity. This should not be a surprise.

> That's how it gets more of its 'offspring' into the next generation.

Only true if it is killing a high proportion of those it infects and too
quickly for them to pass it on before they expire.

It makes perhaps 30% of the people it infects only slightly sick - not enough to notice. Of the remaining 70% - who are symptomatic to some extent - perhaps one in five gets sick enough to need to go into hospital. Of that 14%, some die.

More if they are elderly or have pre-existing problems. But younger people do die too.

The people who don't get sick enough to notice don't spread all that many virus particles.

People who get sick enough to cough and sneeze a lot are better at spreading virus particles, but if they get tested early and promptly isolated the don't spread them for long.

It probably hasn't got the highest possible infectivity - which would imply just getting to the coughing and sneezing phase and not staying there long enough to get noticed and isolated.

It's more complicated than that. Once the infection has got obvious, the infected people are getting isolated and have a much poorer change of infecting new victims. If the infection is dramatic enough to eventually kill you, it's probably too dramatic for optimum infectivity.

OK, I guess it's possible for the virus to become slightly more deadly, if
it becomes even more contagious by the change. And as you say our
actions are selecting which viruses get to infect others.


And I guess I could imagine some other disease that gets transmitted
because of the death the host. And that could then evolve to be more
deadly.
But in general, more contagious and less deadly is how viruses are
expected to evolve.
