We have seen that the process of infection and consequent disease is controlled by a number of factors ranging from the effect of specific genes controlling aspects of pathogenesis to more subjective factors that can be classified as important in overall virulence of the disease. The nature of the viral disease – or more accurately, the viral infection, its severity, the fate of the host, and the fate of the virus causing the disease – is important from a purely medical point of view. But, as importantly, the features of the dynamic interaction between virus and host provide important clues as to how long a particular virus has been associated with its host. Further, the nature of the interaction provides clues as to the evolutionary history of the host.
