Officiating Post COVID-19 ???

Wearing a mask is pretty much useless. The coronavirus has a diameter somewhere between 60-140 nanometers. The pores in the material of the masks people are using are much bigger, meaning the virus can pass right through. In fact, the pore size on the N95 medical mask can filter 99% of particles between 0.1 - 0.3 microns. Sounds impressive, except that converts to 100 - 300 nanometers, again meaning much of the virus can get through the filter.
