I'd agree with you if it was April but it's basically the middle of August so there's no confusion about masks any more. People are well aware of the recommendation of wearing them and are either following the advice or just ignoring it at this point.Though if true, it's amazing that within 6 months the guidance has almost turned completely opposite. In February, we were assured that to contract the virus we had to make physical contact with something that had virus on it then touch our face, mouth, or nose. That's why we were scrubbing our groceries and boiling our mail. If we washed our hands we'd be fine, and that we should not wear masks if we did not have actual symptoms. Now some seem to be telling us that the virus is flying freely through the air all around us and if we don't wear masks we'll probably all die.
No wonder there's such confusion about everything related to this pandemic. I'm following current guidance on wearing masks and distancing (minor things to do if they truly keep us safer), but I can understand why some might be confused.
There are some important worries over coronavirus spreading by aerosol:At one end of the spectrum, there are relatively large droplets, launched often from coughs and sneezes, that have the trajectory of ballistic missiles. These tiny droplets of respiratory secretions can be loaded with infectious virus, cozy in their moist bubbles. But as they are relatively heavy, these droplets tend to fall rapidly to the ground and often don’t make it farther than a meter or two from their launch site.
On the other end of the spectrum, there are aerosols. These are often defined as being less than 5 micrometers in diameter (a micrometer is one-millionth of a meter. For reference, the width of a human hair can range from around 20 micrometers to nearly 200 micrometers.) Aerosols—which are sometimes called droplet nuclei—are lighter than respiratory droplets and can hang in the air, potentially for hours. They can also travel much farther from their launch site, easily traversing and swirling around a large room.
EXACTLY!To point #2, the point of the cloth mask is more to prevent the wearer from spreading their own germs than it is to protect a wearer from receiving someone else’s germs.
But that’s also why the recommendation is six feet and a mask, not either/or.
And that’s why indoor activities are not great ideas right now. Indoor restaurant service, attending the movies, any sort of voluntary indoor activity that you don’t have to do is an unnecessary risk that comes with potential ramifications that reverberate far beyond the individual who chooses to partake.
I think in general people have been too quick to look at all of this as either/or, rather than the idea that each component is a piece in the armor. Socially distance. Wear a mask. Don’t participate in leisure activities indoors.
The worry is the (simple, woven cloth) face coverings most people wear are thought, backed by some data, ineffective against stopping aerosols. They don’t block aerosol spread by spreader or receiver.To point #2, the point of the cloth mask is more to prevent the wearer from spreading their own germs than it is to protect a wearer from receiving someone else’s germs.
This! When anti-maskers use the early recommendations to not wear masks now, it makes no sense. This is the reason the CDC and other health care officials issued that at the beginning.The early no mask necessary ”recommendations“ were bunk. That was motivated mostly out of concern for maintaining supplies of masks for healthcare workers.
Recent testing indicated neck gaiters and bandanas were poor choices for preventing aerosols spread. Even a 1-ply cotton mask was reasonably effective, multiple plies was better.The worry is the (simple, woven cloth) face coverings most people wear are thought, backed by some data, ineffective against stopping aerosols.

Well, they apparently took the sign literally. They wore a mask in order to enter the store, and once in, they figured they didn't need it anymore.I was in a supermarket last night with big signs on the door, "No Mask, No Entry." Several people walking around the store without masks.
Because $10/hr part time retail employees don’t want to screamed at or physically assaulted or worse trying to enforce corporate policy.At this point, if you can get certain people to wear any type of face covering, I think you have to just consider that a victory.
