Are there selection pressures against viral virulence?
For example, does the immune system react less aggressively to “benign” invaders like circoviruses than to more active threats like varicella? Reacting to zero-virulence foreign material (pollen, cat hair) is undesirable, but some of us do it anyway.
Also, I’ve read that some diseases, like sweating sickness, died out because they were too virulent and rapidly killing all susceptible members of the population. Is this true, and is it common enough to be a significant factor in virulence evolution?
