One thing in this study I find totally surprising is this: how can aerosol from different virus classes be differently contagious when passing through a mask? They seemed to have measured that, but it would really be very interesting to get an explanation how this is possible. How does a mask filter the contagion from corona aerosol, but not from rhino aerosol. This is totally perplexing to me.

By comparison, other viruses, such as smallpox and vaccinia, are around ten times larger at about 300 nanometers; while flu viruses are around 80–120 nm. The smaller the virus, the easier it slips through a mask's fibers.
