In 2014, the world avoided a global outbreak of Ebola, thanks to thousands of selfless health workers -- plus, frankly, some very good luck. In hindsight, we know what we should have done better. So, now's the time, Bill Gates suggests, to put all our good ideas into practice, from scenario planning to vaccine research to health worker training. As he says, "There's no need to panic ... but we need to get going."

the disaster we worried about most
was a nuclear war.

That's why we had a barrel like this

When the nuclear attack came,

we were supposed to go downstairs,

Today the greatest risk

doesn't look like this.

29597
2860
00:44
Instead, it looks like this.

00:48
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.
11
45314
2478
00:59
Not missiles, but microbes.
12
47792
3887
01:03
Now, part of the reason for this is that
13
51679
2199
01:05
we've invested a huge amount
in nuclear deterrents.
in nuclear deterrents.
14
53878

But we've actually invested very little
in a system to stop an epidemic.

01:16
We're not ready for the next epidemic.
16
64129

01:20
Let's look at Ebola.
17
68023
1735
01:21
I'm sure all of you read about it
in the newspaper,
in the newspaper,
18
69758
3857
01:25
lots of tough challenges.
19
73615
1606
01:27
I followed it carefully
through the case analysis tools

75221
3655
01:30
we use to track polio eradication.
21
78876
4845
01:35
And as you look at what went on,
22
83721
1852
01:37
the problem wasn't that there was a system
that didn't work well enough,

01:42
the problem was that we
didn't have a system at all.

24
90081
3568
01:46
In fact, there's some pretty obvious
key missing pieces.

25
94589
4439
01:51
We didn't have a group of epidemiologists
ready to go, who would have gone,

01:55
seen what the disease was,
seen how far it had spread.

27
103940
3756
01:59
The case reports came in on paper.
28
107696
2756
02:02
It was very delayed
before they were put online
before they were put online
29
110452
2356
02:04
and they were extremely inaccurate.
30
112808
1974
02:07
We didn't have a medical team ready to go.
31
115492
2366
02:09
We didn't have a way of preparing people.
32
117858
2595
02:12
Now, Médecins Sans Frontières
did a great job orchestrating volunteers.

33
120453
5331
02:17
But even so, we were far slower
than we should have been
than we should have been
34
125784
3096
02:20
getting the thousands of workers
into these countries.
into these countries.
35
128880
3142
02:24
And a large epidemic would require us
to have hundreds of thousands of workers.

36
132022
6985
02:32
There was no one there
to look at treatment approaches.

37
140752
4403
02:37
No one to look at the diagnostics.

02:38
No one to figure out
what tools should be used.

39
146946
3297
02:42
As an example, we could have
taken the blood of survivors,
taken the blood of survivors,
40
150243
3480
02:45
processed it, and put that plasma
back in people to protect them.
back in people to protect them.
41
153723
5435
02:51
But that was never tried.
42
159158
2606
02:53
So there was a lot that was missing.
43
161764
1756
02:55
And these things
are really a global failure.

44
163520
3895
03:00
The WHO is funded to monitor epidemics,
but not to do these things I talked about.
but not to do these things I talked about.
45
168305
5568
03:07
Now, in the movies it's quite different.
46
175049
2793
03:09
There's a group of handsome
epidemiologists ready to go,
epidemiologists ready to go,
47
177842
4832
03:14
they move in, they save the day,
but that's just pure Hollywood.
but that's just pure Hollywood.
48
182674
5772
03:22
The failure to prepare
could allow the next epidemic
could allow the next epidemic
49
190177
3710
03:25
to be dramatically
more devastating than Ebola
more devastating than Ebola
50
193887
3808
03:30
Let's look at the progression
of Ebola over this year.
of Ebola over this year.
51
198735
4796
03:36
About 10,000 people died,
52
204311
2838
03:39
and nearly all were in the three
West African countries.
West African countries.
53
207149
4697
03:43
There's three reasons why
it didn't spread more.
it didn't spread more.
54
211846
2587
03:46
The first is that there was a lot
of heroic work by the health workers.
of heroic work by the health workers.
55
214433
4441
03:50
They found the people and they
prevented more infections.
prevented more infections.
56
218874
3262
03:54
The second is the nature of the virus.
57
222136
2485
03:56
Ebola does not spread through the air.
58
224621
3076
03:59
And by the time you're contagious,
59
227697
2113
04:01
most people are so sick
that they're bedridden.
that they're bedridden.
60
229810
2740
04:06
Third, it didn't get
into many urban areas.
into many urban areas.
61
234220
4191
04:10
And that was just luck.
62
238411
1704
04:12
If it had gotten into a lot
more urban areas,
more urban areas,
63
240115
2240
04:14
the case numbers
would have been much larger.
would have been much larger.
64
242355
3522
04:17
So next time, we might not be so lucky.
65
245877
3589
04:21
You can have a virus where people
feel well enough while they're infectious
feel well enough while they're infectious
66
249466
5064
04:26
that they get on a plane
or they go to a market.
or they go to a market.
67
254530
3312
04:29
The source of the virus could be
a natural epidemic like Ebola,
a natural epidemic like Ebola,
68
257842
3004
04:32
or it could be bioterrorism.
69
260846
1980
04:34
So there are things that would literally
make things a thousand times worse.
make things a thousand times worse.
70
262826
4648
04:39
In fact, let's look at a model
of a virus spread through the air,
of a virus spread through the air,
71
267474
6001
04:45
like the Spanish Flu back in 1918.
72
273475
3595
04:49
So here's what would happen:
73
277630
1930
04:51
It would spread throughout the world
very, very quickly.
very, very quickly.
74
279560
3998
04:55
And you can see over 30 million people
died from that epidemic.
died from that epidemic.
75
283558
5125
05:00
So this is a serious problem.
76
288683
1813
05:02
We should be concerned.
77
290496
1761
05:04
But in fact, we can build
a really good response system.
a really good response system.
78
292257
4435
05:08
We have the benefits of all the science
and technology that we talk about here.
and technology that we talk about here.
79
296692
5144
05:13
We've got cell phones
80
301836
1047
05:14
to get information from the public
and get information out to them.
and get information out to them.
81
302883
3257
05:18
We have satellite maps where we can see
where people are and where they're moving.
where people are and where they're moving.
82
306140
4179
05:22
We have advances in biology
83
310319
2308
05:24
that should dramatically change
the turnaround time to look at a pathogen
the turnaround time to look at a pathogen
84
312627
3826
05:28
and be able to make drugs and vaccines
that fit for that pathogen.
that fit for that pathogen.
85
316453
4869
05:33
So we can have tools,
86
321322
1566
05:34
but those tools need to be put
into an overall global health system.
into an overall global health system.
87
322888
4612
05:39
And we need preparedness.
88
327500
2293
05:41
The best lessons, I think,
on how to get prepared
on how to get prepared
89
329793
2464
05:44
are again, what we do for war.
90
332257
2501
05:46
For soldiers, we have full-time,
waiting to go.
waiting to go.
91
334758
4247
05:51
We have reserves that can scale
us up to large numbers.
us up to large numbers.
92
339005
3311
05:54
NATO has a mobile unit
that can deploy very rapidly.
that can deploy very rapidly.
93
342316
3689
05:58
NATO does a lot of war games
to check, are people well trained?
to check, are people well trained?
94
346005
3450
06:01
Do they understand
about fuel and logistics
about fuel and logistics
95
349455
2428
06:03
and the same radio frequencies?
96
351883
2358
06:06
So they are absolutely ready to go.
97
354241
2538
06:08
So those are the kinds of things
we need to deal with an epidemic.
we need to deal with an epidemic.
98
356779
4355
06:13
What are the key pieces?
99
361134
2167
06:15
First, we need strong health systems
in poor countries.
in poor countries.
100
363301
5290
06:20
That's where mothers
can give birth safely,
can give birth safely,
101
368591
3187
06:23
kids can get all their vaccines.
102
371778
1517
06:25
But, also where we'll see
the outbreak very early on.
the outbreak very early on.
103
373295
4339
06:30
We need a medical reserve corps:
104
378154
1781
06:31
lots of people who've got
the training and background
the training and background
105
379935
2566
06:34
who are ready to go, with the expertise.
106
382501
3352
06:37
And then we need to pair those
medical people with the military.
medical people with the military.
107
385853
4413
06:42
taking advantage of the military's ability
to move fast, do logistics
to move fast, do logistics
108
390266
4151
06:46
and secure areas.
109
394417
1803
06:48
We need to do simulations,
110
396220
2909
06:51
germ games, not war games,
so that we see where the holes are.
so that we see where the holes are.
111
399129
4798
06:55
The last time a germ game
was done in the United States
was done in the United States
112
403927
2796
06:58
was back in 2001,
and it didn't go so well.
and it didn't go so well.
113
406723
3720
07:02
So far the score is germs: 1, people: 0.
114
410453
5037
07:07
Finally, we need lots of advanced R&D
in areas of vaccines and diagnostics.
in areas of vaccines and diagnostics.
115
415490
6119
07:13
There are some big breakthroughs,
like the Adeno-associated virus,
like the Adeno-associated virus,
116
421609
3637
07:17
that could work very, very quickly.
117
425246
3983
07:21
Now I don't have an exact budget
for what this would cost,
for what this would cost,
118
429229
3370
07:24
but I'm quite sure it's very modest
compared to the potential harm.
compared to the potential harm.
119
432599
4496
07:29
The World Bank estimates that
if we have a worldwide flu epidemic,
if we have a worldwide flu epidemic,
120
437095
4645
07:33
global wealth will go down
by over three trillion dollars
by over three trillion dollars
121
441740
3725
07:37
and we'd have millions
and millions of deaths.
and millions of deaths.
122
445465
3867
07:41
These investments
offer significant benefits
offer significant benefits
123
449332
2985
07:44
beyond just being ready for the epidemic.
124
452317
2201
07:46
The primary healthcare, the R&D,
125
454518
2464
07:48
those things would reduce
global health equity
global health equity
126
456982
2830
07:51
and make the world more just
as well as more safe.
as well as more safe.
127
459812
3690
07:55
So I think this should absolutely
be a priority.
be a priority.
128
463502
3362
07:59
There's no need to panic.
129
467514
1466
08:00
We don't have to hoard cans of spaghetti
or go down into the basement.
or go down into the basement.
130
468980
4489
08:05
But we need to get going,
because time is not on our side.
because time is not on our side.
131
473469
3840
08:09
In fact, if there's one positive thing
that can come out of the Ebola epidemic,
that can come out of the Ebola epidemic,
132
477309
6215
08:15
it's that it can serve as an early
warning, a wake-up call, to get ready.
warning, a wake-up call, to get ready.
133
483524
5806
08:21
If we start now, we can be ready
for the next epidemic.

ABOUT THE SPEAKER
Bill Gates - PhilanthropistA passionate techie and a shrewd businessman, Bill Gates changed the world while leading Microsoft to dizzying success. Now he's doing it again with his own style of philanthropy and passion for innovation.
Why you should listen
Bill Gates is the founder and former CEO of Microsoft. A geek icon, tech visionary and business trailblazer, Gates' leadership -- fueled by his long-held dream that millions might realize their potential through great software -- made Microsoft a personal computing powerhouse and a trendsetter in the Internet dawn. Whether you're a suit, chef, quant, artist, media maven, nurse or gamer, you've probably used a Microsoft product today.
In summer of 2008, Gates left his day-to-day role with Microsoft to focus on philanthropy. Holding that all lives have equal value (no matter where they're being lived), the Bill and Melinda Gates Foundation has now donated staggering sums to HIV/AIDS programs, libraries, agriculture research and disaster relief -- and offered vital guidance and creative funding to programs in global health and education. Gates believes his tech-centric strategy for giving will prove the killer app of planet Earth's next big upgrade.
Read a collection of Bill and Melinda Gates' annual letters, where they take stock of the Gates Foundation and the world. And follow his ongoing thinking on his personal website, The Gates Notes. His new paper, "The Next Epidemic," is published by the New England Journal of Medicine.
