It's pretty surprising that we don't have a good idea of how one of the most common (classes of) disease in the world spreads. This reviews the literature and does a bit of synthesis. (The conclusion is "probably mostly large particle aerosols, for adult-to-adult transmission, but more research needed to be confident".)
