Viral Persistence: Evolution of Viral Populations

1980
There is an extensive literature dealing with persistent infections established by a wide variety of animal viruses. Several mechanisms have been suggested that may be involved in the establishment and maintenance of persistent infection by a normally virulent, cytolytic virus.

Evolution, Viral

2009
Recent progress in comparative genomic and structural biology of microbial viruses, together with the discovery of unusual viruses in archaea and a giant virus in eukarya, has rejuvenated discussion on the origin of viruses. Many scientists now believe that viruses predated the Last Universal Common Ancestor (LUCA).

Viral evolution: beyond drift and shift

Current Opinion in Microbiology, 2015
Technological advances have allowed aspects of viral evolution to be explored at unprecedented scales. As a consequence, new quantitative approaches are needed to investigate features of viral evolution that fall outside traditional areas of study, such as antigenic evolution.

Viral evolution in the cosmos

Space travel exposes human beings to unique environmental stressors (e.g., radiation, microgravity) and induces significant physiological changes in hosts, profoundly impacting host-virus dynamics and creating conditions conducive to viral evolution.

Animal vaccination and the evolution of viral pathogens.

Revue scientifique et technique (International Office of Epizootics), 2007
Despite reducing disease, vaccination rarely protects against infection and many pathogens persist within vaccinated animal populations. Circulation of viral pathogens within vaccinated populations may favour the development of vaccine resistance with implications for the evolution of virus pathogenicity and the emergence of variant viruses.
