Thing aren't that much different now, WHO and other org are still trying ( and sadly failling ) to get stuff done to prepare for the next pandemic ( Look at the US for example ). Not everyone can get treated, If someone vulnerable like an elderly person or someone like me catches the new covid variant there is little to no hope of recovery. Even if you perfecly recover covid can leave damaged lung and nerves. And even if treament can be done without consequences, medicine as always warned to prevent rather than treat.

I don't ask for much, put a mask when going in crowded area and vaccinate at least once every six month.
