I wonder if people who are wearing masks while out and about are doing it so that no one tries to speak with them.

There's a lot of information out there that explains wearing a regular surgical-type (non N95) mask does not protect you from coronavirus.

I read some website/blog where a photographer was talking about wearing an N95 when he was out and about. Not smart.

For some reason, the far east folks, were wearing masks even before this pandemic. They are used to it, and it seems, the far east the results seem better. It was announced that S. Korea, China, Taiwan, Singapore had it under control and all these countries, wear masks most of the time, as compared to us. Even now, I have seen only 2 wearing masks, in the past 2 months here.

The problem is the public is not trained in the proper fitting of masks, handling of masks, disposal of masks. The far east countries who wear the masks, probably have years of usage under their belt and it works for them, as their results show.

You can pick up the mask with contaminated hands.
You can contaminate the mask itself when you unpack it.
You have to dispose of the mask after 3 to 6 hours of use.
How do you dispose of the contaminated mask without contaminating yourself and thus others.
Your hands can be contaminated.
Your clothes/hair can be contaminated.
Publically available Masks cannot protect you against airborne pathogens.
Viruses are about 2 Nanometers.

Viruses are not airborne.

N95 masks may not work for common folks, as they have to be fitted properly.

Surgical masks stop everything except airborne pathogens, when used by Medical persons.

N95 Respirators with faceplate stop everything including airborne pathogens.
(There are two type Insulating and Filtering). This item is not available
to the Public, and used by Medical Personnel. Further they have to be
fitted, and have to be disposed after a few hours.

I have seen a lot of pictures and people in Asian countries wearing surgical masks, but I've never seen anyone wearing an N95! They are usually wearing plain surgical-type face masks. Those masks are not the reason for those countries successes in curbing this pandemic. There are many variables.

I agree, N95 require training to put on and use. At this time there is no reason for the public to wear n95 for protection - it just diverts those masks from health care professionals who need them.

Viruses can become airborne through sneezes, coughs and speaking. If Corona viruses did not become airborne then there wouldn't be a social distancing component as part of protective measures.

Again, if the mask is worn by the infected one, it would keep droplets from being shot out far into the air when the wearer coughs.

It doesn't need to be biohazard grade to have a big effect. (even if it is not 100%)

It may keep the corona virus from being expelled.  If it was 100% then the WHO, CDC and other reputable public health organizations would recommend those.

People are free to wear masks for whatever reason they want, but they need to realize the masks limitations- and the fact that the mask may not be doing what they think.

Abstaining from touching one's face is not impossible. But it is important. In fact, it's the most important thing you can do!

The CDC website says transmission occurs when you get the virus into your mouth, nose or eyes. There is no indication that it enters through the skin!

Another factoid: per capita, the US has fewer hospital beds than Italy.  This makes flattening the curve extremely important.
