Imagine a football is a germ, now imagine the football net is a mask, kick the ball into the net and the mesh stops it because the football is bigger than the mesh.
Now, imagine a virus which compared to a football is the size of a pea, throw that into the goal the mesh is too wide apart to stop the pea so a virus would go straight through a mask.
