If it did disappear, sure. But it won't. Way too many infected all over the globe now, eradication is impossible without a vaccine. Either it will eventually infect the entire world, or we'll vaccinate against it. Those are the only two options at this point. Even if an entire nation managed to eradicate it via distancing, it would only take a single carrier arriving by any means from another country to initiate a second wave and restart the clock. Edit: I'm not one to engage in meta, but seriously, what the fuck is with the downvotes? Every word of what I said is casually verifiable with a quick google search and is not at all controversial. There is absolutely no way to eradicate SARS-CoV-2 without global immunity due to its exceptionally high R0 combined with the fact that it's already present all over the globe. The only two ways to achieve global immunity is if everyone gets infected and develops immunity, or everyone is vaccinated. Someone who's hitting downvote, please comment and explain.

Third option: we fight it with drugs and we prevent / reduce hospitalizations, and it becomes a disease like every other.

  Vaccines will help with that, like with the flu.

  No, that's the first option - it will eventually infect the whole world no matter how much you improve outcomes or slow it down. Unmitigated R0 of SARS-CoV-2 is extremely high, we can't keep it contained with spreaders all over the globe creating micro clusters every day. I didn't say it'll kill the whole world, just infect. Many countries have already brought their case rates down to almost 0, and every single one that attempted to resume economic activity saw the case rates spike again, with many now re-introducing distancing measures again. This genie is not going back into the bottle. The first option is actually potentially more viable on a reasonable timeline than vaccination, especially if we manage to find some kind of effective therapeutics which reduce the ICU and mortality rates. There is however a potential issue, which is based on SARS data, immunity in recovered individuals only lasts 1-2 years. So unless there's a concerted effort to eradicate via immunisation, there's a measurable risk that SARS-CoV-2 will become a seasonal repeating wave like Influenza.

    I have no hard data (and I don't think anyone has, at this point), but eradication is IMO going to be tricky even if we have a very potent vaccine, at least looking at how much it took for chicken pox.

      Oh absolutely. Eradicating this thing via vaccination any time in the next 24 months will take a completely unprecedented feat of worldwide collaboration. But I'm optimistic, the current situation has everyone focused on the issue. Except Trump trying to get some special deals for early access or whatever the fuck it is that he's doing.

        Any country that physically manufactures vaccine doses isn't going to allow many exports until they have a sufficient domestic supply. That's not just a Trump thing.
        lbeltrame 6y ago
        That's precisely why many vaccine producers are seeking partnership and starting manufacturing at risk. As an example, Moderna teamed up with Lonza (and also got a big grant from BARDA). Oxford / Vaccitech has deals with Astra Zeneca, Merck, and a few other manufacturers.

  If a useful treatment shows up, that would certainly be an option, though vaccination would be preferable if feasible.
- SpicyLemonZest 6y ago
  The obvious comparison is tuberculosis, where vaccination (albeit not universal vaccination) is a critical component of our control measures. Even if we find a strongly effective treatment, which I agree there's reason for optimism on, we'll still want a vaccine.

    Yeah, lockdown == prevent. ICU == treat. At the moment thats all we have
    - lbeltrame 6y ago
      Many doctors are actually experimenting different treatments, even handling in the ICU has shifted compared to two months ago. The problem is that most of the pharmacological evidence is sparse and anecdotal at worst (except for remedisivir, and now lopinavir/ritonavir/ribavirin/interferon beta). Trials are ongoing and should at least give better answers, or hints. Protocols change among countries or even across hospitals, so it's kind of hard to figure out which treatment is best. There's a lot of road to cover to come to proper treatments, but if we are to believe case reports, it is undoubtedly much better than when the pandemic started hitting the West.

There is another way of looking at this. If an area has contained it once, they have to do it again. They have to try. They are not immune. If the US decides to go it alone on the herd immunity approach, because they are incapable of making any other approach work, and all other countries reduce the infection rate to close to zero over the summer with the lockdown approach, that US travel ban aint getting lifted. Most countries have attempted lockdown, opening up as and when their health services are able to cope. If US citizens were immune but contagious, US citizens would only be free to travel within US borders. Could end up with Lockdown, branded as freedom. In that light it makes sense to what ever the rest of the world does.

Green zones and red zones with strict measures to prevent case importation are also an option. A few countries/regions currently have close-to-zero new cases and may become green zones where economic and other activities will mostly resume to normal. Measures that have been used include quarantine and follow-up contact tracing.
