Yeah I've tried finding an answer to this but I haven't yet found anything that really answers it... Here's how my logic runs, and it may be off but here goes. The time to "contain" the coronavirus was when it was initially breaking out in China. Indications are that the government covered it up for a few weeks which probably made containment impossible. Once they started locking things down, this was already out spreading all over the world. Now that it's global, even if a country could quarantine and 100% eliminate it, what's to stop people from other countries from bringing it in once quarantine's are lifted or like in China where the rate slowed dramatically but it still isn't eliminated? If a significant portion of the population hasn't been exposed, all the quarantine does is slow things down while it's in progress and hurts economic activity but as soon as it is lifted everyone is at risk again. The only thing I can figure logically is that it was done to prevent a complete collapse of the medical facilities and to make the government look like it is taking things seriously... but once lifted everyone is at risk again of a new "wave" starting up. I'm just not sure what the actual benefit of a quarantine is once something like this goes global outside of temporarily slowing things down.
@Jon any thoughts on this?
You’re right.
Quarantines only help to contain the virus initially. If that fails (it did, since it’s global), the second benefit would be to slow the rate at which the virus transmits.
China quarantined initially to try to contain. Then it was self serving isolationism to slow the rate and try not to cripple their economy.
All countries would have had to collectively suspend air travel indefinitely until cases went down, but thanks to modern technology we got screwed pretty quickly.
Covid-19 is here to stay. It’s a new virus and will likely be seasonal like the flu, but can also follow an odd seasonal pattern (or a longer pattern) than the flu. Just like after the 2009 H1N1 outbreak, we now vaccinate for H1N1 strains (usually a different one each year) and that H1N1 virus shows it’s head every flu season.
So SARS CoV-2 won’t go away. No amount of quarantine or preparation can prevent inevitable community spread in every state and county. We are beyond that.
What we can hope for is the fastest development of a vaccine known to man and be able to vaccinate against covid-19 this fall, however we may be waiting until next spring. Oddly enough, whenever the vaccine is available it will be pushed ASAP.
Once you get covid-19 there’s a chance you can be protected or build immunity. This is only initially, this is why the CDC says you can’t get it twice. It will mutate and drift, and you’ll be able to get it again once it does so.
Here’s a video about antigenic drift of flu, which is similar virally:
What is worrisome is the vaccine, even after it’s made and given to a large number of people, may not work.
We see about a 50% effectiveness rate of flu vaccines annually. That’s best case. Now think about 169 published strains of CoV-2 so far due to antigenic drift. Trying to figure out what strain or strains to include in a tiny vaccine will be 80% guesswork and 20% data analysis. But the problem is they have to pick soon, as trials are already beginning. It’s still too early to scientifically pick a predicted strain for next year, as we are just now sequencing the genome. What we are doing now for a vaccine is 100% guesswork. So don’t count on that being our saving grace.
I kinda went on a tangent but wanted to answer the vaccine question someone quoted you and asked.
