These are worms.

00:14
Not the kind of worms you find crawling in the dirt.
1
14089
2586
00:16
These are parasitic roundworms.
2
16699
2154
00:18
They live inside a human being's intestines.
3
18877
2435
00:21
Each of these worms can grow up to 12 inches long,
4
21336
2756
00:24
and there are 200 of them in this jar for a reason,
5
24116
2381
00:26
because that is the number you might typically find
6
26521
2382
00:28
in the belly of a single infected child.
7
28927
2444
00:31
Worm infections have been around for thousands of years.
8
31395
2660
00:34
They have influenced the outcomes of wars,
9
34079
2000
00:36
and they have long stymied human health.
10
36103
1913
00:38
Roundworm, hookworm,
11
38040
1587
00:39
whipworm, schistosomiasis:
12
39651
2023
00:41
infections from these species cause pain and discomfort.
13
41698
3112
00:44
They steal nutrients and zap energy.
14
44834
2093
00:46
They stunt both physical and cognitive growth.
15
46951
2474
00:49
In most cases, these worms may not be fatal,
16
49449
2722
00:52
but paradoxically, that's part of the problem.
17
52195
2179
00:54
It means that many countries
18
54398
1540
00:55
simply have not been able to prioritize their treatment.
19
55962
2732
00:58
There's a social cost to that:
20
58718
1617
01:00
children without access to deworming treatments
21
60359
2192
01:02
have lower rates of school attendance.
22
62575
2043
01:04
Adults who grow up without deworming medicine
23
64642
2112
01:06
are less productive and have lower lifelong earnings.
24
66778
2800
01:09
What intestinal worms do, really,
25
69602
2112
01:11
is limit potential.
26
71738
1427
01:13
Currently, there are 1.7 billion people in the world still at risk for worms.
27
73189
4219
01:17
Six hundred million of them are in Africa.
28
77432
2446
01:19
For every dollar invested in worm control and prevention,
29
79902
3126
01:23
African countries see up to 42 dollars return in economic benefits.
30
83052
4151
01:27
The good news is that deworming treatment is extremely easy.
31
87227
3044
01:30
One to three pills given once or twice a year
32
90295
2245
01:32
is enough to take a child from 200 worms to zero
33
92564
3040
01:35
and to protect them from infection going forward.
34
95628
2423
01:38
In communities where there's a high prevalence of worms,
35
98075
2620
01:40
treatment can be done right at school.
36
100719
1823
01:42
This process is extremely simple and fast.
37
102855
2333
01:45
In Ethiopia, for example, this is done for 20 million children
38
105212
3126
01:48
in a matter of weeks.
39
108362
1786
01:50
The world has come a long way
40
110172
1628
01:51
on getting deworming medicines to the people who need them,
41
111824
2825
01:54
and African governments want to gain more traction.
42
114673
2540
01:57
It's now time to match their ambition.
43
117237
2109
01:59
The END Fund will work with governments
44
119729
1945
02:01
to create a plan that drastically reduces the burden of disease caused by worms.
45
121698
4719
02:06
They’ll work together to ensure prevention and treatment programs
46
126441
3138
02:09
can serve everyone.
47
129603
1294
02:10
The END Fund has an audacious idea:
48
130921
2179
02:13
they believe we are the generation to end sickness from worm infections forever.
49
133124
4380
02:17
The key is not simply to build new programs from scratch,
50
137528
3195
02:20
but to amplify the efforts of the programs that are already taking shape.
51
140747
3642
02:24
By examining the problem of how worms transmit disease,
52
144413
3112
02:27
the END Fund has identified five key areas where they can drive improvement.
53
147549
3920
02:32
Number one: lower the cost of treatment.
54
152017
2443
02:34
Many pharmaceutical companies offer deworming medicines for free,
55
154484
3049
02:37
so the END Fund works with the right partners
56
157557
2143
02:39
to coordinate their delivery.
57
159724
1567
02:41
They will continue to secure drug donations
58
161315
2420
02:43
for additional at-risk populations.
59
163759
2637
02:46
They can now do it for less than 25 cents per child per year.
60
166982
3778
02:51
Number two: focus on prevention.
61
171120
2430
02:53
The END Fund calls in the right partners to educate communities
62
173574
3002
02:56
on sanitation and hygiene
63
176600
1569
02:58
in order to change behaviors around things like hand-washing
64
178193
2842
03:01
and latrine use,
65
181059
1151
03:02
ensuring people are not continually reinfected.
66
182234
2693
03:04
Number three: invest in innovation.
67
184951
2709
03:07
The END Fund has contributed to deworming
68
187684
2075
03:09
by introducing innovative techniques that effectively target and treat people.
69
189783
4240
03:14
They will test new delivery methods,
70
194047
1768
03:15
target the environments where parasites thrive
71
195839
2192
03:18
and influence behavior change.
72
198055
1711
03:19
Number four: monitor and evaluate.
73
199790
2713
03:22
The END Fund collects detailed data on all programs on a regular basis
74
202527
3795
03:26
to help them get better and better over time.
75
206346
2712
03:29
Number five: increase local ownership.
76
209082
2842
03:31
At all stages of the process,
77
211948
1619
03:33
the END Fund works with government and local stakeholders
78
213591
3167
03:36
to encourage cofinancing commitments that support deworming efforts.
79
216782
3778
03:40
They also worked with African philanthropists
80
220584
2176
03:42
and corporate leaders to partner on these efforts.
81
222784
2847
03:45
There's an incredible opportunity to work together to create a new system
82
225655
3722
03:49
for disease elimination for the next decade and beyond.
83
229401
3222
03:52
Part of the money the END Fund needs
84
232647
1755
03:54
will go directly toward delivering deworming treatments
85
234426
2601
03:57
to communities that need it
86
237051
1398
03:58
and part will go towards facilitating the handover of programs
87
238473
3421
04:01
to local ownership.
88
241918
1301
04:03
Together, these efforts will create prevention and treatment programs
89
243243
3461
04:06
that are sustainable far into the future.
90
246728
2586
04:09
If this plan gets fully funded for the next six years,
91
249338
3492
04:12
tens of millions of people will receive deworming treatment.
92
252854
3657
04:16
With that, countries will be interrupting the cycle of disease transmission
93
256883
3722
04:20
at all levels,
94
260629
1171
04:21
and most importantly, people will experience significant improvements
95
261824
3853
04:25
in their mental, physical and social health.
96
265701
2951
04:28
Just imagine the potential that will be gained
97
268676
2518
04:31
when people can stop worrying about these
98
271218
2419
04:33
and can put their energy into things like these.
