Although I can appreciate the all or nothing aspect of mask wearing, personally, this isn’t confusing information. It has long been true that if one can socially distance, particularly if the distance is larger than 6 feet, and is outdoors, one is fairly safe from infection, even if unvaccinated. Granted, very low risk is not no risk, but it is comparatively of little consequence.
In the areas of Manhattan I visit, up until this recent announcement, almost everyone - 99+% - wore masks outdoors while walking, regardless of distance and regardless of vaccination status, the exceptions being crowded party areas of 20-somethings. Now, the walls come have down a bit, but still, everyone has masks on indoors and most people wear masks outdoors. I still wear my masks when walking down the street, even when almost completely alone, partially because it is easier than having to frequently move my mask up or down.
As for the CDC messaging, although things were mishandled in the beginning, it has been fairly linear since then, and if one is reading the news and journals, this new guidance is in line with what we know about risk. One could actually argue that they could have said this sooner. As an aside, it might even be a messaging ploy to incentive some people to get vaccinated.
BTW, we are still super careful, wash our hands when coming in from the outside, even if we haven’t touched anything. We still wipe down grocery deliveries, but will likely stop that soon. It’s just the idea of anything infectious that drives this bit of craziness, but we are a bit happier that way, feeling just a bit more secure, without intrusive irrational concerns about cleanliness.
