According to this Scientist, the size of the material gaps in the blue surgical masks are up to 1000 times greater than the size of the virus! And cloth-mask gaps can be 500,000 times the size.
I have been told much the same by a few Medicos.
Waterson writes for his audience. The argument about the size of the virus versus mask materials is utterly ridiculous. The virus doesn't commute in the air as single viral entities. It can't because, apart from anything else, it needs to be in a sustaining fluid. The virus is carried in respiratory droplets many, many times larger than the virus itself. That's what the masks stop.
