It is impossible to say when this crisis will last for many more days The situation is becoming direr I don't think that in countries where the epidemic has improved and returned to normal new corona patients are being identified Nothing can be prevented. I got in the new news that this coronavirus will last 4 years in the world I don't know if it is correct but the government needs to take more drastic steps to eradicate the coronavirus Then this crisis can be overcome very quickly.
This quarantine could last whole year and coronavirus could be beaten in couple years - this is a possibility indeed. But there are other more positive ones out there.
This way or another - you should understand that when quarantine will come to an end this won't change our world all the way back to its "normal" state in one day.
Its going to be a long and pretty hard process
