Abstract
Viruses that cause persistent infections maintain themselves more effectively in nature than those causing acute and limited infections. There is a tendency for persistent viruses to evolve towards a state of minimal pathogenicity in the host. Vertical transmission, with integration of viral into host genome, represents the state of perfect parasitism.Entities:
