Bill Gates TED Talk Transcript from 2015: Warns of Pandemics, Epidemics
In a TED Talk from 2015, Bill Gates warned that the world is not prepared for an epidemic, pandemic, or outbreak. This feels all too relevant with the 2020 coronavirus (COVID-19) pandemic. Read the full transcript of his TED Talk here.
Bill Gates: (00:07)
When I was a kid, the disaster we worried about most was a nuclear war. That’s why we had a barrel like this down in our basement, filled with cans of food and water. When the nuclear attack came, we were supposed to go downstairs, hunker down, and eat out of that barrel. Today, the greatest risk of global catastrophe doesn’t look like this. Instead, it looks like this. If anything kills over 10 million people in the next few decades, it’s most likely to be a highly infectious virus rather than a war. Not missiles, but microbes.
Bill Gates: (01:03)
Now, part of the reason for this is that we have invested a huge amount in nuclear deterrence, but we’ve actually invested very little in a system to stop an epidemic. We’re not ready for the next epidemic. Let’s look at Ebola. I’m sure all of you read about it in the 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 wasn’t that there was a system that didn’t work well enough. The problem was that we didn’t have a system at all.
Bill Gates: (01:46)
In fact, there are some pretty obvious key missing pieces. We didn’t have a group of epidemiologists ready to go who would have gone, seen what the disease was, see 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 didn’t have a medical team ready to go. We didn’t have a way of preparing people. Now, Medecins Sans Frontieres 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 to have hundreds of thousands of workers.
Bill Gates: (02:32)
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 them, but that was never tried. 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, it’s quite different. There’s a group of handsome epidemiologists ready to go. They move in, they save the day, but that’s just pure Hollywood. The failure to prepare could allow the next epidemic to be dramatically more devastating than Ebola.
Bill Gates: (03:30)
Let’s look at the progression of Ebola over this year. About 10,000 people died, and nearly all were in the three West African countries. There’s three reasons why it didn’t spread more. The first is 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 you’re contagious, most people are so sick that they’re bedridden. Third, it didn’t 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. So next time we might not be so lucky.
Bill Gates: (04:21)
You can have a virus where people feel well enough while they’re 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 bio-terrorism. And so there are things that would literally make things a thousand times worse. In fact, let’s look at a model of a virus spread through the air, like the Spanish flu back in 1918.
Bill Gates: (04:49)
So here’s what would happen. It would spread throughout the world very, very quickly. And you can see there’s over 30 million people die from that epidemic. So this is a serious problem. We should be concerned. But in fact, we can build a really good response system. We have the benefits of all the science and technology that we talked about here. We’ve 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 they’re moving. We have advances in biology that should dramatically 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.
Bill Gates: (05:41)
The best lessons I think on how to get prepared or 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. And 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 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.
Bill Gates: (06:13)
What are the key pieces? First is we need strong health systems in poor countries. That’s where mothers can give birth safely. Kids could get all their vaccines, but also where we’ll see the outbreak very early on. We need a medical reserve corps. Lots of people who’ve 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 military’s ability to move fast, do logistics and secure areas.
Bill Gates: (06:48)
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 didn’t go so well. So far the score is germs one, people zero. Finally, we need lots of advanced R&D in areas of vaccines and diagnostics. There are some big breakthroughs like adeno-associated virus that could work very, very quickly.
Bill Gates: (07:21)
Now, I don’t have an exact budget for what this would cost, but I’m quite sure it’s very modest compared to the potential harm. The world bank estimates that if we have a worldwide flu epidemic, global wealth will go down by over $3 trillion, and we’d have millions and millions of deaths. These investments offer significant benefits beyond just being ready for the epidemic. The primary health care, the R&D, those things would reduce global health equity and make the world more just as well as more safe.
Bill Gates: (07:55)
So I think this should absolutely be a priority. There’s no need to panic. We don’t 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. In fact, if there’s one positive thing that can come out of the Ebola epidemic, it’s that it can serve is an early warning, a wake-up call to get ready. If we start now, we can be ready for the next epidemic. Thank you.
