“When there is an influenza threat, drop everything and focus on risks from influenza pandemics. When SARS spreads, focus on unknown respiratory diseases. This approach helps to quell public concern, but it's a hugely inefficient way to deal with future risks.”

“Pandemics do not occur randomly. From malaria and influenza to AIDS and SARS, the lethal microbes have come, in the first instance, from animals, especially wild animals. And we increasingly know which parts of the world pose the greatest risk for future incursions.”

“The world can now maintain an acute infection in a way that is unprecedented in the history of life on our planet.”

“Don't assume that what we currently think is out there is the full story. Go after the dark matter, in whatever field you choose to explore.”

“If an alien visited Earth, they would take some note of humans, but probably spend most of their time trying to understand the dominant form of life on our planet - microorganisms like bacteria and viruses.”

“The features of globalization have huge consequences on pandemics. It just connects us so much more closely... And as a consequence, every one of these viruses that passes from animals to humans has the capacity to infect all of us.”

“With epidemics, people have been standing on the shore, waiting for the gusher to hit the ocean. But to prevent epidemics, you have to look at the various little sources that feed into the river.”

“If we can provide even a few months of early warning for just one pandemic, the benefits will outweigh all the time and energy we're devoting. Imagine preventing health crises, not just responding to them.”

“We've put huge resources into predicting tsunamis, hurricanes, and earthquakes. HIV/AIDS is like an earthquake that's lasted 30 years and touched every country on the planet. We have such incredible capacity to think about the future, it's time we used it to predict biological threats. Otherwise we'll be blindsided again and again.”

“I work to create systems that can accurately detect pandemics early, determine their likely importance, and, with any luck, crush those that have the potential to devastate us.”

“We know there are certain types of viruses that are nasty - influenza, for instance, is an area that is not a blindside. But a lot of viruses have come out of nowhere, like H.I.V., or to a certain extent SARS. Because we know we have the potential to be blindsided, we really have to investigate the unknowns.”

“The reality is: By the time swine flu got on the radar screen of global public health, it had already spread. It was already in the States, it was in Mexico, it was in New Zealand. By the time it reaches that point, you've lost the ability to contain it.”

“If we can contain and monitor animal viruses at an earlier stage - when they're first entering human populations, preferably before they've had a chance to become human-adapted, certainly before they've had a chance to spread - we can head off pandemics altogether.”

“Because pandemics almost always begin with the transmission of an animal microbe to a human, it's work that takes me all around the globe - from rain forest hunting camps of central Africa to wild animal markets of east Asia.”

“We live in a world fraught with risk from new pandemics. Fortunately, we also now live in an era with the tools to build a global immune system.”

“There are commonalities among all the pandemics that occur, and we can learn from them. One commonality is that they all come from animals. And the other commonality is that we wait too long.”

“About 20 percent of the genetic information in your nose doesn't match anything that we've ever seen before.”

“As a species, I think we have no choice but to try and forecast pandemics.”

“We see new things all the time. We see new retroviruses out there - which is the category that HIV falls into - and we're very, very concerned because this is the part of the world where HIV jumped from chimpanzees to humans.”

“We may have charted all the continents on the planet, and we may have discovered all the mammals, but that doesn't mean that there's nothing left to explore on Earth.”
