Here's an old study that seems apropos

https://www.ncbi.nlm.nih.gov/pubmed/18556606

Claims that for respiratory infections, handwashing with our without antibacterial soap only reduces transmission by about 21%.

So cloth masks (someone here posted it reduces by 25%?) is better than handwashing? =)
