Ireland“One of the more surprising aspects of the Covid crisis – for me at any rate – is the fact there has been so much disagreement about the wearing of facemasks and the mode of transmission of Covid 19. Yes, it’s a new virus but it strikes me that given the threat that pathogens pose to mankind, one would have thought that the underlying physics of sprays and aerosols, not to mention the transport of particles through multilayer membranes might be very well understood at this stage, especially given the computing power at our disposal.
