The attenuation you seem to be banking on only happens if there is selective pressure toward it. The selective pressure is usually a product of "too deadly or too strong a response prevents the host from spreading" so weaker strains that let the host spread more win out in a game theoretical sense by out-competing. This is not a likely force in this case--this is already spreading really really effectively, so I think the force behind attenuation is missing and your assumption is entirely faulty. > So far more people have died than WWII. > What the fuck??? You are right on this one, bad bad misquote on my part.
