Axelrod speculated that pathogens might have a couple of infection modes.  If
they're the only ones around, or if the host seems healthy, it makes sense to
play nice and go for modest scattering into the environment over time, not
hurting the host too much.  If the host seems to be getting weaker, this can
be seen as foreseeing the end of the iterated Prisoner's Dilemma game, and the
pathogen might explode in a frenzy of rapid reproduction, weakening the host
even more.  So at some point in improving nutrition, decreasing stress, or
decreasing overall pathogen load, there might have been a switch in how we
were being infected.
