Virulence Evolution in Epidemics

This article explored the effect of virulence evolution within an epidemic and how it affects its spread on the “front line”.  Using the equation for virulence which is basically an organisms ability to cause damage to a host organism vs its ability to replicate, vs its ability to spread. the result of the study found that organism that mutated for a high virulence lead the front line of a spreading epidemic. however, behind the front, more opportunistic infections take advantage of a weakened host and eventually out compete the high virulent organism.
