I wore masks when necessary and still got COVID.
Masks, even N95 masks, stop particles down to a certain size. They filter out molecules larger than that size.
The Covid virus is smaller than that size. It’s about 90 nanometers wide.
This doesn’t mean the mask doesn’t work. Covid viruses don’t float in the air alone. They are generally always riding on an aerosol particle of moisture and it is 1 micron or larger in size. The masks stop that.
So whatever test you’re thinking about . . . do the test correctly.
Same here, along with massive COVUD scarring on my lungs.
