Microorganisms are not calculating entities. They don’t care what they do to you any more than you care what distress you cause when you slaughter them by the millions with a soapy shower. The only time a pathogen cares about you is when it kills you too well. If they eliminate you before they can move on, then they may well die out themselves. This in fact sometimes happens. History, Jared Diamond notes, is full of diseases that “once caused terrifying epidemics and then disappeared as mysteriously as they had come.” He cites the robust but mercifully transient English sweating sickness, which raged from 1485 to 1552, killing tens of thousands as it went, before burning itself out. Too much efficiency is not a good thing for any infectious organism.
