I'm sorry if I sound pessimist here but... before Covid was a thing and we all lived happily without masks, hugging each other, and whatever... flu was killing a bunch of people every year, each time with a different strain that required a different vaccine against it. Scientists were kind of worried about a possible H5N1 pandemic originating once again from, guess what, a virus that would jump from a different animal, in this case chickens, to humans. We also got stuff like Ebola, Zika, some other flu strains (Hong Kong flu possibly? In the 60s?)
Yet we all lived without masks, we hugged each other, we didn't even think about the possible dangers of doing so. I guess the most important reason is just that most of the diseases we'd have going around were "known" and we had good ways to deal with them, but we're not infallible on that front anyways! There probably are way more complicated sociological reasons behind the reason why, even after something like the Spanish Flu, we collectively decided "oh ok we're no longer in danger" or "we can accept having these diseases spread"... I would have no idea what those are, but I guess it just happened at some point, and the same could happen with Covid as well sooner or later.
One thing I hear people say around here is to focus just on the health system: if it can handle itself alright, then we're good to go, otherwise, that's not good. I suppose everyone can agree on the fact that having to choose, as a doctor, who you'll try to save and who you have to leave behind is the hardest decision ever and something you should never be put through - so that's surely something we'd have to avoid. Can we avoid it if we let Covid, as it is now, spread without control? Definitely not! But will it always be like that? Well, the answer seems to be "no" once again :)
We're not perfect or infallible, we just try to survive some way or another, and that's fine <3 <3 <3
Sending hugs and positivity (not to Covid obviously) to everyone who sees this, you absolutely deserve it after reading what I wrote up there...
