I thought 'The Hot Zone' was fascinating, mesmerizing. It's one of the things that got me interested in Ebola.
The more cases of Ebola infection we have, the more chances there are for the virus to mutate in a particular way that adapts it well to living in humans, replicating in humans, and perhaps transmitting from human to human.
Ebola isn't a respiratory virus. It doesn't spread through the airborne route. So it's not likely to spread like wildfire around the world and kill tens of thousands or hundreds of thousands of people. That's what I think of as the next big one.
Viruses have to live somewhere. They can only replicate in living creatures. So, when the Ebola virus disappears between outbreaks, it has to be living in some reservoir host, presumably some species of animal.
We're shaking loose viruses and dislodging them from their natural ecological limitations, places where they aren't very abundant and have competition, even within a single animal. We introduce them into a new, rich habitat called the human population, where they can flourish more abundantly and cause more trouble.
Of course anyone who truly loves books buys more of them than he or she can hope to read in one fleeting lifetime. A good book, resting unopened in its slot on a shelf, full of majestic potentiality, is the most comforting sort of intellectual wallpaper.
