There's decent evidence that it can be passed through excretion, too. Active viral loads have been found in restrooms far in excess of what could be explained otherwise. The theory is that there's live viral particles in feces, and they get aersolized with the force of flushing. This is also consistent with the finding that diarrhea is a common symptom of coronavirus (I had it) -- there seems to be some kind of GI tract involvement that you don't see with e.g. the flu.
