What's left to determine is how the virus will spread via reverse zoonosis: deer-tick-mouse.This is somewhat off topic...but I think many have lost sight of the realities of Covid19.
Everyone is going to get Covid eventually. If we are VERY lucky Omicron will give way to an even less dangerous variation...but probably only by degrees.
Omicron is FAR less deadly than Alpha was... and less dangerous than Delta was.
What's left to determine is Omicron's likelihood of producing chronic Covid symptoms...aka long-covid.
We'll know the answer to that soon.
If the answer is Omicron does not cause chronic Covid... and if it is analogous to influenza in hospitalisation and death rates...it is likely time to put the fear of contacting Covid19 behind us.
