that mandatory masks have been fully implemented in public gathering places,
and assuming the following data in the first column, then

Note 1: Microscopic objects usually have some physical effects that are different from normal objects, such as electrostatic effect, capillary effect, matter wave effect, diffraction, and so on.
Note 2: The floating virus is not a bullet or smoke, it
is neither rigid nor difficult to destroy! Spherical
viruses may be more easily destroyed than linear viruses. Perhaps
from a normal point of view, an 8-micron hole in a mask is difficult to block a
0.08-micron virus, but the actual situation may not be the case. The virus that
wants to break through the mask is likely to be squeezed or pulled by
microscopic forces and destroyed, and it may become a dead virus.
The above content is based on idealized assumptions and requires real data support.
