Parasite mortality (regardless of whether it is caused by the host's immune response or due to parasite-independent host mortality) is predicted to be a strong determinant in the evolution of optimal parasite growth rate inside the host.
I develop a simple model of optimal parasite virulence as a function of several variables that influence the relative rates of horizontal and vertical transmission.
Under these assumptions, we propose a "law of diminishing returns," which predicts that increased transmission opportunities between the same pair of hosts will lower optimal parasite virulence.
