According to the current knowledge, the virus SARS-CoV-2 has a diameter of 60 nm to 140 nm [nanometers (billionth of a meter)] [16], [17], while medical and non-medical facemasks’ thread diameter ranges from 55 µm to 440 µm [micrometers (one millionth of a meter), which is more than 1000 times larger [25]. Due to the difference in sizes between SARS-CoV-2 diameter and facemasks thread diameter (the virus is 1000 times smaller), SARS-CoV-2 can easily pass through any facemask.
Here’s the science. Leaders in Democrat-led states should rejoice at this information since it explains why their Covid case numbers keep going up despite their ongoing lockdowns while Republican-led states are doing better.
Real science gives answers that Dr. Anthony Fauci fails to grasp.
