Laurie Garrett, author of “The Coming Plague,” gave this talk in 2007 to a small group of TED University audience. This talk and her insights are suddenly more relevant than ever. Read the full text of Laurie Garrett’s talk below:
Laurie Garrett – Author
So the first question is, why do we need to even worry about a pandemic threat? What is it that we’re concerned about?
When I say “we,” I’m at the Council on Foreign Relations. We’re concerned in the national security community, and of course, in the biology community and the public health community.
While globalization has increased travel, it’s made it necessary that everybody be everywhere, all the time, all over the world. And that means that your microbial hitchhikers are moving with you.
So a plague outbreak in Surat, India becomes not an obscure event, but a globalized event — a globalized concern that has changed the risk equation.
And Katrina showed us that we cannot completely depend on government to have readiness in hand, to be capable of handling things. Indeed, an outbreak would be multiple Katrinas at once.
Our big concern at the moment is a virus called H5N1 flu — some of you call it bird flu — which first emerged in southern China, in the mid-1990s, but we didn’t know about it until 1997.
At the end of last Christmas, only 13 countries had seen H5N1. But we’re now up to 55 countries in the world, have had this virus emerge, in either birds, or people or both.
In the bird outbreaks we now can see that pretty much the whole world has seen this virus except the Americas. And I’ll get into why we’ve so far been spared in a moment.
In domestic birds, especially chickens, it’s a 100% lethal. It’s one of the most lethal things we’ve seen in circulation in the world in any recent centuries.
And we’ve dealt with it by killing off lots and lots and lots of chickens, and unfortunately often not reimbursing the peasant farmers with the result that there’s cover-up.
It’s also carried on migration patterns of wild migratory aquatic birds. And there has been this centralized event in a place called Lake Chenghai, China.
Two years ago, the migrating birds had a multiple event where thousands died because of a mutation occurring in the virus, which made the species range broaden dramatically. So that birds going to Siberia, to Europe, and to Africa carried the virus, which had not previously been possible.
We’re now seeing outbreaks in human populations — so far, fortunately, small events, tiny outbreaks, occasional clusters. The virus has mutated dramatically in the last two years to form two distinct families, if you will, of the H5N1 viral tree with branches in them, and with different attributes that are worrying.
So what’s concerning us?
Well, first of all, at no time in history have we succeeded in making in a timely fashion, a specific vaccine for more than 260 million people. It’s not going to do us very much good in a global pandemic.
You’ve heard about the vaccine we’re stockpiling. But nobody believes it will actually be particularly effective if we have a real outbreak.
So one thought is: after 9/11, when the airports closed, our flu season was delayed by two weeks.
So the thought is, hey, maybe what we should do is just immediately — we hear there is H5N1 spreading from human to human, the virus has mutated to be a human-to-human transmitter — let’s shut down the airports.
However, huge supercomputer analyses, done of the likely effectiveness of this, show that it won’t buy us much time at all. And of course, it will be hugely disruptive in preparation plans.
For example, all masks are made in China. How do you get them mobilized around the world if you’ve shut all the airports down? How do you get the vaccines moved around the world and the drugs moved, and whatever may or not be available that would work?
