It's simple if you don't have a mask on you can spread the problem to someone else who then share it with others. If you have the mask on then you can't share with others and the problem stops at you.
The masks and other protocols used by the general public are like putting a screen door on a submarine. Actually protecting yourself from something as small as a virus, or containing it, (which is actually much more difficult) requires far more than could practically be done on a mass scale.
Masks are an entirely psychological phenomenon, it makes you think you are doing *something", and actually have some control over a situation that you have no real control over. The underlying issue is that, having lived lives of obscene luxury and safety (for 3 generations now) people cannot fathom that there are situations beyond their practical control, and therefore demand a solution on the assumption that there must be one.
Ultimately, unless a vaccine is found in the next few months, I would guess the ultimate death toll will be about the (deaths per infection) *320 million. That seems to mean around 300,000-500,000 people might die in the USA. Assuming this was a naturally-developed virus, *it is no one's fault*, *nothing practical can be done to alter it*. Nature and the real world are a pretty harsh and there are some problems that *cannot be solved*, thinking that "this is the 21st century, we have moved beyond this sort of thing, this can't be happening to us!" is nonsense. We have been living a charmed life, but eventually probability catches up with you.
Of course, the "it takes a village" types are all too happy to promise to do something and be seen to be doing something, effective are not, and all too happy to find a "solution" that eliminates any semblance of personal choice, because it plays to their end goals, that is, eliminating the uniquely American concept of individual liberty.
Every proposed apocalyptic "crisis" for the last 50 years has, oddly, had the same solution.
It also gives you a clearly visible signal of this "compliance", and thus wearing a mask almost immediately became your indication of virtue, or not, so it makes you feel superior to be more conservative about "safety".
If you don't want to catch Wuhan Flu, then don't go out and wait at home for a vaccine. That is your only realistic method of avoiding infection. Not practical on a mass scale, of course, and no guarantees at all, but its what little you can actually do that is effective to protect yourself. Otherwise, you wearing a mask, or other people wearing masks, will accomplish exactly nothing for "safety".

p.s. Wuhan flu *absolutely is* a health crisis, it is a very real disease that you will almost certainly be exposed to (and maybe already have been), some chance of developing detectable symptoms from, and a very small but realistic chance of dying from. People who think it is entirely fake are probably just doing the same thing as the "safety screechers", they might realize that there is no real defense from it, and for their own peace of mind, must assume that it's just made-up. It definitely is not made up, the effects of been greatly exaggerated for purposes of manipulation, but very real and much more dangerous that a typical seasonal flu.
For certain groups, in fact, the statistics are staggering, if you are over 75 - 80, it's just short of a death sentence. Part of that is that in the most incompetent responses (New York and Florida), they had policies that nearly guaranteed exposure of large numbers of people already compromised to the point they were in nursing homes. A lot of this was avoidable with even simple precautions,
