The pandemic is an insidious threat -- you cannot sense its presence -- and there's no instrumental means of detection (unlike other common insidious threats like electricity and methane). All the indicators are lagging indicators; we can know where it was, not where it is.
What that means is you do not know -- you cannot know -- what your risk is. It is by-definition impossible to know what your risk is. (Remember that while it's statistically unlikely that you personally happen to be standing next to the person who was so startlingly fortunate as to have the "lethal as MERS" Omicron mutation occur during their initially asymptomatic infection, that's not a statement about your risk. It's a statement about how likely that event is in the population, given a certain set of assumptions. Your risk? inherently unknown. Assume that the person next to you is shedding.)
Your single best means of avoiding death is to get (and keep getting) vaccinated. This is not enough to prevent spread, and spread is how the disease gets worse. So vaccination is not sufficient unto your civic duty. You must also avoid infection.
Your single best means of avoiding infection -- and you want to avoid infection, because infection increases your risk -- is to wear a mask.
Today, in the current state of the plague, wear a mask means a half-face respirator with a full gasket seal, no exhaust valve, and P100 filters. (You're not a health-care professional with a need to dispose of your mask. You're going outside absolutely as little as possible -- which means you don't, unless necessary to avoid material harm -- you're bagging your mask in an impermeable plastic bag when you get home, and since it's a respirator, you can take the filters off and wash it from time to time. Slather it with hand-sanitiser more frequently than that. Yes, this costs more up front, but given that you're going to need it for at least the next year, your total cost is less this way.)
If you leave the house, you do it with the mask on. It stays on the whole time you're out of the house.
When can we stop wearing masks everywhere?
When the disease is extirpated.
Given full population vaccination, universal mask use, and time, the disease will be extirpated.
Yes, there's a whole lot of public support required to get there; it's not as simple as always wearing your mask. Yes, there are a bunch of evil people on Team Virus who think freedom means they are free to commit contagion. At a minimum, don't be like that. Wear your mask.
