Per Chris Martenson[1], three reasons for every person to wear a mask:

- Stops infected people [including asymptomatic] from expelling infectious particles.

- Helps remind you not to touch your face [and precludes direct touch to mouth and nose--where mucus membranes are vulnerable].

- Much better chance of a low inoculum [a smaller initial viral load results in less severe symptoms].

Just, please please please make sure they're home-made masks. If you have any professionally-created surgical masks, you should donate them to healthcare workers, who need them much more than you. I live in Manhattan, and I still see people walking around outside with "real" masks.

Good point. Also, from the site:

> "Note: Please do not buy surgical or N95 masks because we need to keep those available for the doctors, nurses and first responders so they can stay healthy and care for the ill."

Has the mask supply situation improved? I still see empty shelves for things like gloves, sanitizers, etc.

I just ordered a couple washable ones from Etsy.

The video convinced me I shouldn't keep waiting for them to be back in stock at the store.

US Surgeon General continues to recommend against this for some reason

> for some reason They recommend against wearing medical to help cull the shortage, and they recommend against wearing non-medical because they can provide a false sense of security, especially when worn incorrectly. Both very good reasons, IMO. I just assume that anyone wearing a mask is doing so because they're infected, as per the recommendations, and I'm giving them a wide berth.

Another reason to wear a mask.

One thing often missed with the mask story is that they (generally) stop you touching your mouth and face as frequently. Assuming touching your mouth with a 'dirty' hand is a major infection vector, then a home made mask would indeed be of some use.

Hong Kong scientists also developed and tested a few home made designs, make of them what you will.

I like these instructional videos about how to put masks on and take them off, because they emphasize that you should be washing your hands when you put the masks on and take them off.

The mask won't do as much good if you just end up transferring the virus to your face after taking it off.

Yes! China is cranking out 300,000,000 surgical masks per day and they're available on Ali Express. I have 100 in my hand made on 3/15 - most are going to the local hospital today. Have 200 on order and should arrive in five days.
