This reminds me of some current dogma (forgot whose idea) that viruses are
usually very virulent when they enter a new host population/species, and in
general become less so with time, so as to preserve their susceptible host
population for future generations of viruses. However, I would just like to
point out that variola major was with us for millenia, with no known outside
reservoir, and yet was particularly virulent. Successful, too, until we put
our minds to problem. So, at least in this case, the dogma doesn't hold up.
