These results are not surprising to those who know about The Evolution of Virulence (PDF) in infectious diseases.  Viruses, not having DNA, do not reproduce themselves as precisely as do higher organisms.  As a result, there is much more genetic variation within their descendants, resulting in rapid evolution, which: Increases Communicability.  Natural selection favors those virus components that allow the virus to spread to more hosts. Reduces Deadliness.  Natural selection...(Read Full Post)
