The problem is getting those "certified" masks.
Instead, we are told to just cover our faces with a piece of cloth and problem solved.
Like I said, if this actually works, then every Muslim country on the planet should have been at an advantage since they already force half their population to do this.
I don´t know, but if in Portugal and many other countries it is possible to go to a supermarket and buy them, what is the problem in the USA? Don´t you have an official institution that certifies them?
As for pieces of cloth, again, there are several types of masks, made from several types of materials. Certified cloth masks have several layers of fabric whith certain specifications for example in terms of the size of the "pores" so to speak. In my wife's company, they are wearing washable cloth masks, they can be washed 50 times without losing their properties. In Portugal, many companies that before were producing garments, have reconverted to make cloth masks according to the specs from scientific institutions.
If you go out and areina closed space, you need to wear a mask, plain and simple. We arenow in week 3 of reopening, and the number of new cases has stabilized at a growth rate of less than 1%, say around 200-250 new cases a day. This is a good indication so far, also Rt is below 1, which is good.
Your reference to muslims is misguided, simply because the cloth used by women to cover their faces does not have the necessary specifications as a proper cloth mask, as mentioned above.
