✦ Synopsis

The transmission dynamics of viruses in a replicating cell population is investigated, assuming that viral mutants differ in their efficiencies of horizontal and vertical transmission. As a generic result we find that competition between such different viral strategies need not select for increasing basic reproductive rates. We illustrate evolutionary trajectories that lead to increased viral latency even at the expense of lower basic reproductive rates and lower equilibrium abundance. In some cases oscillations in the prevalence of different mutants are obtained.

We explored the evolutionary importance of two factors in the adaptation of RNA viruses to their cellular hosts, size of viral inoculum used to initiate a new infection, and mode of transmission (horizontal versus vertical). Transmission bottlenecks should occur in natural populations of viruses and
