Study Ranks the Best and Worst Materials for Face Masks
Some coverings work better than others when it comes to blocking virus spray
En espaņol | You don't need a fancy medical-grade mask to deter the spread of the coronavirus, but some face coverings do work better than others, according to a new study published in the journal Science Advances.
Researchers at Duke University tested the effectiveness of 14 commonly available masks and found that surgical masks and N95 respirators without valves worked the best at blocking respiratory droplets from projecting into the air when a person talks. A variety of double-layer polypropylene and cotton masks also reduced a significant amount of spray from normal speech.

Notice how they did not study how facemasks work with this bug.
Also notice that this information re droplets we should have had many years ago.
Our experts sure do suck!
I choose my own words like the Americans of olden times........before this dystopia arrived.

Abortion rights dogma can obscure human reason & harden the human heart so much that the same person who feels
empathy for animal suffering can lack compassion for unborn children who experience lethal violence and excruciating
pain in abortion.
Unborn animals are protected in their nesting places, humans are not. To abort something is to end something
which has begun. To abort life is to end it.
