Pathogenesis of Viruses

Viral pathogenesis is the series of actions by which viral infections leads to deadly viral diseases as a result of implantation, replication, spread to disease prone sites and shedding of virus into the environment. Effective facilitated factors leads affect pathogenic events includes accessibility of virus with tissue, cell susceptibility for virus multiplication and susceptibility of virus to respective host defenses. In addition natural selection also favors the dominance of low-virulence for most of the virus strains.
