- I liked the way Gordon phrased it; I suspect he answered a question
- different from what you meant to ask. He says (if I may presume to
- interpret) that the organisms don't "home in" on the particular areas
- they infect; rather that, like seeds scattered in the wind, they show
- up everywhere but only find conditions suitable for growth (soil) in
- these particular areas and fail to thrive everywhere else.

- Now -- if you are asking why the viruses grow in certain areas and not
- in others, that is a different question. I assume it has to do with
- availability of warmth, moisture, absence of direct exposure to air,
- etc.; one of the doctors or scientists will have to answer that
- question, which I don't think was exactly what you asked.
