That's not a stupid question at all. From what I've read and understand, the 'standard' masks (the cheap ones - surgical masks) are not a 100% protection, however it's in the >50% range. Probably enough to greatly limit the R0 and change the expontential curve to a linear one (I may be wrong - definitely not an expert). I'm too amazed by the magnitude of the measures that are being taken as opposed to less invasive and technical solutions. Adding other stupid questions: - why we can't just decide to test everybody - what's the bottleneck ? - why we can't just produce the n95 respirators in sufficient quantites and distribute free of charge to everybody - not even making it mandatory to wear in public - if enough people wear it, the virus won't spread
