Viral Evolution
Viral evolution refers to the process by which viruses change over time through mutations and natural selection. As viruses reproduce, random genetic changes can occur, which may create new characteristics. Some of these changes might help the virus survive better in its environment or evade the immune system. When a virus spreads, those with advantageous traits are more likely to be transmitted and dominate the population. This ongoing evolution can lead to new virus strains, affecting how diseases spread and the effectiveness of vaccines and treatments. Understanding this helps scientists anticipate and combat viral outbreaks.
