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.

I was a prodigy who learned how difficult writing was only after getting published. I paid my dues later.

I'm a white, middle-class male who had a happy childhood in Ohio. The world does not need me to be a novelist.

You can't take a knife on a plane anymore, but you can get on carrying a virus.

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.

One of the things that's particularly nefarious about Ebola is that it continues to live in a dead person for some period of time after death. A person who's been dead for a day or two may still be seething with Ebola virus.

There's a belief in some cultures that if a person experiences good fortune in financial terms and does not share the good fortune, when that person becomes ill with a mysterious fever and dies, people tend to say: 'Aha! It was because he didn't share. It was the spirits who brought him down.'

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.

On April 3, 2014, Jane Goodall turned 80. The iconic blond ponytail has gone gray, but the sparkle of intelligence, sly humor, and fierce dedication still shines from her hazel eyes.

I thought 'The Hot Zone' was fascinating, mesmerizing. It's one of the things that got me interested in Ebola.

Most Americans know nothing about the African forest, and it seems to them a very scary, spooky dangerous place. I've spent a lot of time in the forests of central Africa. I know they're beautiful places that contain a lot of different kinds of creatures, including some that carry Ebola.

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.
