Thats why we had a barrel like this down in our basement, filled with cans of food and water. When the nuclear attack came, we we
2、re supposed to go downstairs, hunker down, and eat out of that barrel. 0:36 Today the greatest risk of global catastrophe doesnt look like this. Instead, it looks like this. If anything kills over 10 million people in the next few decades, its most likely to be a highly infectious virus rather than
3、a war. Not missiles, but microbes. Now, part of the reason for this is that weve invested a huge amount in nuclear deterrents. But weve actually invested very little in a system to stop an epidemic. Were not ready for the next epidemic. 1:19 Lets look at Ebola. Im sure all of you read about it in th
4、e newspaper, lots of tough challenges. I followed it carefully through the case analysis tools we use to track polio eradication. And as you look at what went on, the problem wasnt that there was a system that didnt work well enough, the problem was that we didnt have a system at all. In fact, there
5、s some pretty obvious key missing pieces. 1:50 We didnt have a group of epidemiologists ready to go, who would have gone, seen what the disease was, seen how far it had spread. The case reports came in on paper. It was very delayed before they were put online and they were extremely inaccurate. We d
6、idnt have a medical team ready to go. We didnt have a way of preparing people. Now, Mdecins Sans Frontires did a great job orchestrating volunteers. But even so, we were far slower than we should have been getting the thousands of workers into these countries. And a large epidemic would require us t
7、o have hundreds of thousands of workers. There was no one there to look at treatment approaches. No one to look at the diagnostics. No one to figure out what tools should be used. As an example, we could have taken the blood of survivors, processed it, and put that plasma back in people to protect t
8、hem. But that was never tried. 2:52 So there was a lot that was missing. And these things are really a global failure. The WHO is funded to monitor epidemics, but not to do these things I talked about. Now, in the movies its quite different. Theres a group of handsome epidemiologists ready to go, th
9、ey move in, they save the day, but thats just pure Hollywood. 3:21 The failure to prepare could allow the next epidemic to be dramatically more devastating than Ebola Lets look at the progression of Ebola over this year. About 10,000 people died, and nearly all were in the three West African countri
10、es. Theres three reasons why it didnt spread more. The first is that there was a lot of heroic work by the health workers. They found the people and they prevented more infections. The second is the nature of the virus. Ebola does not spread through the air. And by the time youre contagious, most pe
11、ople are so sick that theyre bedridden. Third, it didnt get into many urban areas. And that was just luck. If it had gotten into a lot more urban areas, the case numbers would have been much larger. 4:16 So next time, we might not be so lucky. You can have a virus where people feel well enough while
12、 theyre infectious that they get on a plane or they go to a market. The source of the virus could be a natural epidemic like Ebola, or it could be bioterrorism. So there are things that would literally make things a thousand times worse. 4:38 In fact, lets look at a model of a virus spread through t
13、he air, like the Spanish Flu back in 1918. So heres what would happen: It would spread throughout the world very, very quickly. And you can see over 30 million people died from that epidemic. So this is a serious problem. We should be concerned. 5:03 But in fact, we can build a really good response
14、system. We have the benefits of all the science and technology that we talk about here. Weve got cell phones to get information from the public and get information out to them. We have satellite maps where we can see where people are and where theyre moving. We have advances in biology that should d
15、ramatically change the turnaround time to look at a pathogen and be able to make drugs and vaccines that fit for that pathogen. So we can have tools, but those tools need to be put into an overall global health system. And we need preparedness. 5:40 The best lessons, I think, on how to get prepared
16、are again, what we do for war. For soldiers, we have full-time, waiting to go. We have reserves that can scale us up to large numbers. NATO has a mobile unit that can deploy very rapidly. NATO does a lot of war games to check, are people well trained? Do they understand about fuel and logistics and
17、the same radio frequencies? So they are absolutely ready to go. So those are the kinds of things we need to deal with an epidemic. 6:12 What are the key pieces? First, we need strong health systems in poor countries. Thats where mothers can give birth safely, kids can get all their vaccines. But, al
18、so where well see the outbreak very early on. We need a medical reserve corps: lots of people whove got the training and background who are ready to go, with the expertise. And then we need to pair those medical people with the military. taking advantage of the militarys ability to move fast, do log
19、istics and secure areas. We need to do simulations, germ games, not war games, so that we see where the holes are. The last time a germ game was done in the United States was back in 2001, and it didnt go so well. So far the score is germs: 1, people: 0. Finally, we need lots of advanced R&D in area
20、s of vaccines and diagnostics. There are some big breakthroughs, like the Adeno-associated virus, that could work very, very quickly. 7:20 Now I dont have an exact budget for what this would cost, but Im quite sure its very modest compared to the potential harm. The World Bank estimates that if we h
21、ave a worldwide flu epidemic, global wealth will go down by over three trillion dollars and wed have millions and millions of deaths. These investments offer significant benefits beyond just being ready for the epidemic. The primary healthcare, the R&D, those things would reduce global health equity
22、 and make the world more just as well as more safe. 7:54 So I think this should absolutely be a priority. Theres no need to panic. We dont have to hoard cans of spaghetti or go down into the basement. But we need to get going, because time is not on our side. 8:08 In fact, if theres one positive thing that can come out of the Ebola epidemic, its that it can serve as an early warning, a wake-up call, to get ready. If we start now, we can be ready for the next epidemic. 8:25 Thank you.
