something that affects 99% of people on earth. Something that would immediately prompt 99% of humanity to seek medical treatment, if I'm meant to read more into this than just the word's literal meanings, a hospital is a place of hospice, a place to seek care, or help, a place you go to get something corrected or fixed.

This could be any number of things, but what's something all of humanity shares in common, we have to eat food, we have to drink water, we need to breathe air, there's stuff we need in order to live, but the other 1% needs that same stuff too.

then what about the wording "put 99% of people in the hospital" does this imply it would place people in hospitals, not draw them there, or drive them there, but require them to go there? If so why? What could be such a dire threat to life as to require almost all of humanity to immediately NEED medical treatment?

A revelation about something we use that's not actually safe, but that were told is? the vaccines perhaps? a contaminant in the water or food that is doing something not good for the body or mind? i think the air is too broad reaching, if it was the case you'd see the elites always breathing separate air from everyone else.

I'm also not really convinced it would be something that would just cause such a shock it would immediately render most of humanity too ill to function without treatment, shock hits hard, but it doesn't last long, and not everyone is equally prone to it.
