Good article Michael,
But stealthy maladies abound, though perhaps not as viral infections. If you substitute Psychiatrist for Hair Stylist in the example above, I have seen one or two examples, and some people would say that Lyme Disease can masquerade as a whole host of other problems. So while that malady is bacteriological, I imagine there are already biological viruses which induce symptoms that mimic something else - and so fall in the category indicated.
Or perhaps I just have a hard time believing that humans are cranking out computer viruses that outdo what is seen in nature. But maybe computer viruses really are more virulent. Pretty scary stuff, either way.
