Viral Diversification in Host/Host Populations

Evolution is fuelled by genetic diversity, which makes it easier to adapt to new settings. Viruses are among the most rapidly developing organisms on the planet. Viruses, particularly RNA viruses, gain genetic variety quickly due to short generation durations, enormous population sizes, and high mutation rates. This genetic diversity is essential for viruses to adapt to new challenges like the immune system and medicines. A virus's evolutionary dynamics can differ between hosts and populations. Within-host evolution research bridges the gap between laboratory investigations of virus evolution and large-scale phylodynamic analysis. They can figure out how well global processes are replicated on smaller sizes and how well experimental diseases mimic natural infections.
