There have been studies which have found that the virus can aerosolize, but it hasn't been established that infectious spread occurs this way. For example, it could be that viral concentrations in an aerosolized form aren't enough to cause an infection (or maybe they can get there, in prolonged close quarters, but by then you're being exposed multiple ways, so it doesn't matter or can't be determined). Either way it seems that the protocol for preventing transmission probably won't change much; the current protocols (including ubiquitous mask usage) have been enough for Korea, Taiwan etc. to control the spread.
