It's not on the Gates' Foundation radar but how about a very high quality, matching set of mask and glasses/goggles? Costing about $30.<p>The mask is reusable and the glasses fit very close to the skin around the eyes...perhaps even with a neoprene apron that seals against the face and the mask. It would also stop your hands from easily and unconsciously touching your eyes, nose and mouth.<p>The idea here is that, in public, it protects the wearer against others and protects others from the wearer. If widely adopted this gear would vastly reduce the cost of the "test and track" effort and everyone would just feel safer in public.<p>This virus is unlikely to be going away any time soon. Some say it will be with us for a "very long time" because even a vaccine is likely to be effective only over the short term and therefore the "herd immunity" will never really take place. We need to get serious about the long term strategy. This could be a one cheap, quick and effective tactic for reopening.
