It looks more and more as if SARS is not, in the strict sense, airborne. It is waterborne, but that means it can be transmitted by things like sputum and saliva that travel through the air. That may seem like quibbling, but it matters when we are considering what a mask can block. A mask that is not able to block a tiny virus can very well be able to block droplets of sputum and saliva.
