For covid from what I've seen. Next 8 weeks or so are going to be insane. It will be very hard to get medical treatment even necessary treatment. Who knows what shape the medical system will be in after this, Anyways covid is kinda hit the limit for how contagious it can be since people only have so many interactions. Now its about immune invasion which mutations for are more rare. Immunity for covid seems to not last long but for the about 3 months after omicron we should be pretty safe as almost everyone will catch it. Then its about getting better and more multifaceted vaccines which is happening and then distribute and use them. If we don't do that another covid strain that's good at evading the immune system will pop up. Also a lot of the high risk people will be dead. So it will turn into a more seasonal looking flu sorta thing.
