1 - Modification is comparatively slow compared to propagation. When it does occur (think influenza) it is basically a new system.
2 - Not relevant to the argument in any major way (as far as catalysts go) - I only put that in because, in the case of humans, are symptomatic.
3 - Catalyst can be homogeneous or heterogeneous. The former 'roaming' around in the reactant-filled surroundings, the later awaiting the reactant to come to it.
4 - Catalyst do form 'immune' substance - that is they change the material with which they react until it no longer reacts.
A catalyst is a material that takes part in a reaction by lowering the activation energy (barrier to reaction occurring). They undergo no net change in their own concentration, but may in fact be changed in the reaction they facility, such as exchanging their original (atomic) content for new (such changes can be observed via isotopic labeling studies).
If you're looking for some sort of religiously rigorous correlation between a conscious macroscopic system and a non-conscious microscopic system then you read the wrong post.

Where the theory falls apart is that it doesn't go beyond "infected".
i.e. it assumes that everyone infected gains immunity, where the reality is that 9.5% (based on today's figures[^]), rather than become immune, die.
I'd say that the cost of such "evolutionary immunity" is a tad on the high side.
"Acceptable losses" is a term reserved for use by psychopaths and maniacs.

In a recent study, those who die from a disease are permanently immune to it.
Obviously, here our A->B includes a that unfortunate byproduct. It's still out of the reaction.
And the 'catalyst' model still holds. In the real world of reactions, one wants to go from A to B with the help of catalyst C. What happens is that one goes from A to B, gets some B1, B2, D, E, Q . . . and a lot of the effort in catalyst research is to get as much A to B as possible relative to the rest (under milder conditions, if possible).
- For what it's worth, I did a computer simulation of this in the 80's - gas/surface interactions - and then had experimental proof as well to the hypothesis. And if I explained it in only rigorously scientific terms it would be basically unreadable to most lounge readers.

Not all infections give permanent immunity. For most corona viruses it only lasts between 6 and 24 months. We're at least a year from being able to start characterizing this one.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Granted. Permanent immunity is not guaranteed. For that matter, it may even slowly mutate its way through the population until the new version comes back to strike again (flu, cold, etc.) and permanent immunity doesn't help much.
This[^], along with interesting considerations, agrees with your point. Particularly towards the end.
On a sunny note, of sorts, the author expect a likely scenario is it joining four other Corona virus' that are typically with us along with the flu, sharing the season - but since kill or severely sickening the hosts doesn't spread the virus very well, it will likely evolve to an illness with generally minor symptoms. Alas, not in a time frame anywhere near 'Yesterday'

Actually disease propogation is a difusion process caused by random contact with contagious people rather than random motion of molecules.
Rules to live by:
1, wash your hands with an antiviral, not antiseptic or anti-bacterial.
Avoid large groups of people who are coughing.
3. Don't kiss anyone with a runny nose.

I can see the diffusion point of view. On the microscopic level, all chemical process are prety much diffusion processes.
They have some other tricks, too, such as a something like proton transfer in aqueous solutions: the proton doesn't have to actually move - the charge propagates along the (H20)n chain. Fortunately, disease should be able to mimic this. Unfortunately, however, human behavior (as in deciding they need to hoard) does . . .
I just picked out one model that wasn't too difficult to describe. Is a person sneezing an SN1 or SN2 reaction?
Unlike the chemical in a reaction it has one special caveat that most annoying: unpredictable behavior of sentient reactants.

Shelves are bare... no meat, veggies or bread either. They promised shipments within the next couple of days.

Good grief.
I went to my local supermarket this morning, and bought my usual bread, 6 chicken breasts, and some beef mince for meatballs. Along with liquid soap, and anti-bacterial clothes washing liquid. They had no pasta, no toilet rolls, but I keep those in stock anyway ... Either wales is being "more sensible" than the USA, or more restrained, I guess.

I think that's very much area dependent.
I live in a location that has a pretty dense population (my home is on a 40x100 foot lot). There was a first-round buying frenzy and shelf-emptying but they were restocked very quickly. Some nuts keep up the over-buying but some stores are enforcing nut-mittigation limits.
The current hassle, so far as I can see, is stores limiting the number of concurrent customers. You are cued until someone leaves. One in after one out. Another thoughtful change is some stores instituting some seniors-only early shopping hours.
Umm? What's left? Well, I already had laid in a good supply of single malts so I'm ready for whatever comes.
