WEBNov 11, 2016 · Pathogenesis encompasses all the sequence of events accompanying acute and persistent infections. It includes entry of the virus into the body, multiplication and spread, the development of tissue damage, and the production of an immune response; the latter may contribute to the pathology of an infection.
Viral Pathogenesis - Medical Microbiology - NCBI Bookshelf
WEBPathogenesis is the process by which an infection leads to disease. Pathogenic mechanisms of viral disease include (1) implantation of virus at the portal of entry, (2) local replication, (3) spread to target organs (disease sites), and (4) spread to sites of shedding of virus into the environment. Factors that affect pathogenic mechanisms are ...
