But, if it ends an endemic, how bad is it? There are things like the common cold that cause relatively few deaths yearly. There's the flu that causes, what, 60K deaths yearly. Or it could be worse to a lot worse.
Is covid worse than the flu once covid is no longer novel? Does covid continue to disproportionately target the elderly and immunocompromised even once those subgroups have ample exposure? And they get booster shots with the hope that the antibodies are capable of neutralizing more serious infections? And then, eh, cross your fingers.
In retrospect, once COVID escaped Wuhan, I think there was probably never a shot at near term full suppression. Now that an extremely infectious version has arrived, I agree long term suppression is probably out as well, though I also hope I will be wrong and natural immunity will turn out to be sufficiently sterilizing.
Long term, I don’t think we know how worried we should be about endimicity, but there is reason for optimism as COVID actually mutates at a much lower rate than the flu which will make it harder to get out ahead of the immune system. Or just consider the historical record where it seems clear that the impact of infectious disease depends primarily on structural factors like population density, sanitation, infection control technology, etc. Is there really a structural change that now allows disease to be deadlier than the past or would the best guess still be that this turn out like past outbreaks? The main structural change I see is much more global travel, which means rapid global spread but, if anything, less deadliness. In the past, you got deadly diseases because of isolated populations acting much like animal reservoirs for the development of novel viruses. Wilderness destruction increasing exposure to animal viruses may be a factor on the other side, but again I don’t see why they would be able to sustain much more deadly ongoing infectiousness than in the past.
Will it be worse for the elderly and immunocompromised? Surely, yes, and I don’t think we should just accept that. I think a return to the idea the we should try to eliminate the deadlier bugs would be a good idea. If there’s a way to genocide some of the nastier ones that play extremely dirty tricks, like HIV, we ought to do it. Barring full suppression, better control like using inhaled vaccines instead of injections for respiratory viruses would be great. I don’t quite understand why we don’t already do that. We have inhaled flu vaccines but they seem to be much less used. I tried to get one last year in part because there was some evidence that they might have side anti-COVID benefits through action at the site of infection, but hardly anyone was offering it. You had to go way out of town to some place that didn’t take my insurance, so I didn’t go for it. Would like to know what the deal with that is.
It may have been unrealistic to think containment at some point would happen, but yeah with delta circulating whatever odds there were have certainly decreased. I guess fingers crossed natural infection after vaccination (or without vaccination) will lead to a more sterilizing immunity. Time will tell.
The slow rate of mutation is reason for optimism, certainly. Though, does it really matter for the foreseeable future if it doesn't mutate at all? It offers plenty of a risk in the near term as is.
In the end, it all comes down to will we get sterilizing immunity with natural infections.
If yes, reason for optimism.
If no, can history offer insight? I'm not so sure. While, yes we have more sanitary conditions and better medicine (like horse dewormer) including monoclonal antibodies, we also have a much higher population density and that seems to trump all other factors. To illustrate this point, look at measles. Measles is said to have an R naught of 12-18, so certainly higher than even the most liberal estimates of delta's R naught which is somewhere around 6-9.
https://ourworldindata.org/grapher/meas ... untry=~USA
The US topped out at 630 measles cases per YEAR / 100K people in a year (1938). Comparatively, nearly every state in the nation topped 630 covid new cases per WEEK / 100K people in 2020. There are like 9 states at or above that rate currently.
The US had roughly 6,000 covid cases in 2020 / 100K citizens and have another, roughly, 6,000 covid cases in 2021 / 100K citizens with the fall months still to go. And, this latest wave is with the vaccines and with at least a year of exposures to the virus.
Granted, the measles had been around, so it wasn't novel, but at those types of rates (if they can be trusted), it's not like there was a lot of immunity in the population prior to the vaccine becoming available.
Perhaps they just kept poor records back then. But, it's not like measles was a difficult diagnosis or difficult to establish it as a cause of death. The death rate topped out in 1923 at 9.x / 100K citizens. Covid killed ~100 people / 100K citizens in 2020. It's killed ~80 people / 100K citizens in 2021 so far. The only optimistic thing that can be said in this comparison is the death rate fell for measles and likely will fall for covid. Regardless, the starting points are so, so different, I don't know much can be gleaned other than general platitudes.

Again, if there's no sterilizing immunity from natural infections, I don't see anything good happening in the near (or distant) future. The virus continues to spread. Sure, it mutates slowly, but if we go to a let er rip mentality with a virus that can spread even among those that have immunity from severe cases, and with 8+ billion people on the planet, and with vaccines that are specifically targeted at one single protein of the virus, as important as that protein may be, I'm reminded of Jeff Goldblum
