"People do stupid things.
0
16260
2000
"La gent fa estupideses.
00:18
That's what spreads HIV."
1
18260
2000
Això és el que escampa el VIH."
00:20
This was a headline in a U.K. newspaper,
2
20260
2000
Això és un titular d'un diari britànic,
00:22
The Guardian, not that long ago.
3
22260
2000
<i>The Guardian</i>, de no fa gaire.
00:24
I'm curious, show of hands, who agrees with it?
4
24260
3000
Podeu aixecar les mans si hi esteu d'acord?
00:29
Well, one or two brave souls.
5
29260
2000
Bé, hi ha un parell de valents.
00:31
This is actually a direct quote from an epidemiologist
6
31260
3000
Això és una cita textual d'una epidemiòloga
00:34
who's been in field of HIV for 15 years,
7
34260
2000
que ha estudiat el VIH durant 15 anys,
00:36
worked on four continents,
8
36260
2000
ha treballat en 4 continents
00:38
and you're looking at her.
9
38260
2000
i que us parla ara mateix.
00:40
And I am now going to argue
10
40260
2000
I ara argumentaré
00:42
that this is only half true.
11
42260
2000
que això és només mig cert.
00:44
People do get HIV because they do stupid things,
12
44260
3000
La gent agafa el VIH perquè fa estupideses,
00:47
but most of them are doing stupid things
13
47260
2000
però molts fan estupideses
00:49
for perfectly rational reasons.
14
49260
3000
per motius ben racionals.
00:52
Now, "rational" is the dominant paradigm
15
52260
3000
De fet, la racionalitat és el model base
00:55
in public health,
16
55260
2000
de la salut pública,
00:57
and if you put your public health nerd glasses on,
17
57260
3000
i si us poseu les ulleres d'entesos en salut pública,
01:00
you'll see that if we give people the information that they need
18
60260
3000
veureu que si donem a la gent la informació
01:03
about what's good for them and what's bad for them,
19
63260
2000
sobre el que és bo i dolent per ells,
01:05
if you give them the services
20
65260
2000
si els donem els serveis
01:07
that they can use to act on that information,
21
67260
2000
que poden usar amb aquesta informació
01:09
and a little bit of motivation,
22
69260
2000
i els donem una empenta,
01:11
people will make rational decisions
23
71260
2000
prendran decisions racionals
01:13
and live long and healthy lives.
24
73260
2000
i tindran vides llargues i sanes.
01:15
Wonderful.
25
75260
2000
Genial.
01:17
That's slightly problematic for me because I work in HIV,
26
77260
3000
Això és un pèl problemàtic quan treballes amb el VIH.
01:20
and although I'm sure you all know
27
80260
2000
Estic segura que sabeu que el VIH
01:22
that HIV is about poverty and gender inequality,
28
82260
3000
té a veure amb la pobresa i la desigualtat de gènere,
01:25
and if you were at TED '07
29
85260
2000
i si vau ser al TED 2007,
01:27
it's about coffee prices ...
30
87260
2000
té a veure amb el preu del cafè...
01:29
Actually, HIV's about sex and drugs,
31
89260
3000
De fet, el VIH va de sexe i droga
01:32
and if there are two things that make
32
92260
2000
i, si hi ha res que torni
01:34
human beings a little bit irrational,
33
94260
2000
els humans un xic irracionals,
01:36
they are erections and addiction.
34
96260
3000
són les ereccions i les addiccions.
01:39
(Laughter)
35
99260
2000
(Rialles)
01:41
So, let's start with what's rational for an addict.
36
101260
3000
Vegem què és racional per a un addicte.
01:44
Now, I remember speaking to an Indonesian friend of mine, Frankie.
37
104260
3000
Recordo una conversa amb un amic d'Indonèsia, el Frankie.
01:47
We were having lunch and he was telling me
38
107260
2000
Mentre dinàvem em parlava de quan
01:49
about when he was in jail in Bali for a drug injection.
39
109260
3000
va ser a la presó de Bali per injectar-se droga.
01:52
It was someone's birthday, and they had very kindly
40
112260
2000
Era l'aniversari d'algú i havien aconseguit
01:54
smuggled some heroin into jail,
41
114260
2000
heroïna de contraband
01:56
and he was very generously sharing it out
42
116260
3000
i el de l'aniversari la repartia generosament
01:59
with all of his colleagues.
43
119260
2000
amb tots els companys.
02:01
And so everyone lined up,
44
121260
2000
Tots van fer cua,
02:03
all the smackheads in a row,
45
123260
2000
heroïnòmans en fila,
02:05
and the guy whose birthday it was
46
125260
2000
i el noi de l'aniversari
02:07
filled up the fit,
47
127260
3000
va omplir la xeringa
02:10
and he went down and started injecting people.
48
130260
2000
i va començar a injectar a tothom.
02:12
So he injects the first guy,
49
132260
2000
Injecta el primer,
02:14
and then he's wiping the needle on his shirt,
50
134260
3000
eixuga l'agulla amb la samarreta
02:17
and he injects the next guy.
51
137260
2000
i injecta el següent.
02:19
And Frankie says, "I'm number 22 in line,
52
139260
4000
I el Fankie diu: "Sóc el 22è de la cua
02:23
and I can see the needle coming down towards me,
53
143260
3000
i veig l'agulla que se m'acosta
02:26
and there is blood all over the place.
54
146260
2000
i està plena de sang.
02:28
It's getting blunter and blunter.
55
148260
2000
S'està desafilant cada cop més.
02:30
And a small part of my brain is thinking,
56
150260
3000
I en part penso
02:33
'That is so gross
57
153260
2000
«Això és repugnant
02:35
and really dangerous,'
58
155260
2000
i molt perillós»,
02:37
but most of my brain is thinking,
59
157260
2000
però en realitat penso
02:39
'Please let there be some smack left
60
159260
2000
«Si us plau, que en quedi una mica
02:41
by the time it gets to me.
61
161260
2000
quan m'arribi.
02:43
Please let there be some left.'"
62
163260
2000
Si us plau, que en quedi una mica.»"
02:45
And then, telling me this story,
63
165260
2000
Llavors,
02:47
Frankie said,
64
167260
2000
em va dir:
02:49
"You know ... God,
65
169260
2000
"Saps... Hòstia,
02:51
drugs really make you stupid."
66
171260
3000
les drogues et tornen idiota."
02:55
And, you know, you can't fault him for accuracy.
67
175260
3000
I no li pots negar que té tota la raó.
02:58
But, actually, Frankie, at that time,
68
178260
3000
Però, en aquells temps, el Frankie
03:01
was a heroin addict and he was in jail.
69
181260
2000
era un heroïnòman i era a la presó.
03:03
So his choice was either
70
183260
2000
Havia d'escollir entre
03:05
to accept that dirty needle or not to get high.
71
185260
3000
acceptar una agulla bruta o no col·locar-se.
03:08
And if there's one place you really want to get high,
72
188260
2000
I si hi ha un lloc on et vols col·locar,
03:10
it's when you're in jail.
73
190260
2000
és a la presó.
03:12
But I'm a scientist
74
192260
2000
Però jo sóc una científica
03:14
and I don't like to make data out of anecdotes,
75
194260
2000
i no converteixo les anècdotes en dades.
03:16
so let's look at some data.
76
196260
2000
Vegem dades de debò.
03:18
We talked to 600 drug addicts
77
198260
3000
Vam parlar amb 600 drogoaddictes
03:21
in three cities in Indonesia,
78
201260
2000
de 3 ciutats d'Indonèsia
03:23
and we said, "Well, do you know how you get HIV?"
79
203260
2000
i els vam preguntar: "Sabeu com agafeu el VIH?"
03:25
"Oh yeah, by sharing needles."
80
205260
2000
"I tant, compartint les agulles."
03:27
I mean, nearly 100 percent. Yeah, by sharing needles.
81
207260
3000
De debò, quasi el 100%, compartint les agulles.
03:30
And, "Do you know where you can get a clean needle
82
210260
2000
"I sabeu on podeu aconseguir agulles netes
03:32
at a price you can afford to avoid that?"
83
212260
2000
a un preu assequible per evitar-ho?"
03:34
"Oh yeah." Hundred percent.
84
214260
2000
"I tant." El 100%.
03:36
"We're smackheads; we know where to get clean needles."
85
216260
2000
"Som heroïnòmans; sabem on trobar-les."
03:38
"So are you carrying a needle?"
86
218260
2000
"I ara portes cap agulla?"
03:40
We're actually interviewing people on the street,
87
220260
2000
Entrevistàvem gent al carrer,
03:42
in the places where they're hanging out and taking drugs.
88
222260
2000
en llocs on prenien drogues.
03:44
"Are you carrying clean needles?"
89
224260
2000
"Portes cap agulla neta ara?"
03:46
One in four, maximum.
90
226260
3000
1 de cada 4 com a màxim.
03:49
So no surprises then that
91
229260
2000
No ens ha de sorprendre que
03:51
the proportion that actually used clean needles
92
231260
2000
la proporció que havia usat
03:53
every time they injected in the last week
93
233260
2000
agulles netes la setmana anterior
03:55
is just about one in 10,
94
235260
3000
fos 1 de cada 10
03:58
and the other nine in 10 are sharing.
95
238260
3000
i que els altres 9 les compartissin.
04:01
So you've got this massive mismatch;
96
241260
2000
I hi ha aquesta discordança abismal;
04:03
everyone knows that
97
243260
2000
tothom sap que
04:05
if they share they're going to get HIV,
98
245260
2000
si comparteixen agafaran el VIH,
04:07
but they're all sharing anyway.
99
247260
2000
però malgrat tot ho fan.
04:09
So what's that about? Is it like you get a better high if you share or something?
100
249260
3000
Per què? La col·locada és millor si comparteixes?
04:12
We asked that to a junkie and they're like, "Are you nuts?"
101
252260
3000
Ho vam preguntar a un jonqui: "Esteu bojos?"
04:15
You don't want to share a needle anymore than you want
102
255260
2000
Vols compartir una agulla tant com vols compartir
04:17
to share a toothbrush even with someone you're sleeping with.
103
257260
3000
un raspall de dents, fins i tot amb la persona amb qui vas al llit.
04:20
There's just kind of an ick factor there.
104
260260
2000
Fa una mica de fàstic.
04:22
"No, no. We share needles because we don't want to go to jail."
105
262260
3000
"No. Les compartim perquè no volem anar a la presó."
04:26
So, in Indonesia at this time,
106
266260
3000
A Indonèsia, actualment,
04:29
if you were carrying a needle and the cops rounded you up,
107
269260
3000
si portes una agulla i la policia te la troba,
04:32
they could put you into jail.
108
272260
2000
et poden enviar a la presó.
04:34
And that changes the equation slightly, doesn't it?
109
274260
2000
I això altera l'equació lleugerament, no?
04:36
Because your choice now is either
110
276260
3000
Però ara has d'escollir entre
04:39
I use my own needle now,
111
279260
4000
faig servir la meva agulla
04:43
or I could share a needle now
112
283260
2000
o podria compartir
04:45
and get a disease that's going to
113
285260
2000
i agafar una malaltia
04:47
possibly kill me 10 years from now,
114
287260
2000
que probablement em matarà en 10 anys,
04:49
or I could use my own needle now
115
289260
3000
o podria fer servir la meva agulla
04:52
and go to jail tomorrow.
116
292260
3000
i anar a la presó demà.
04:55
And while junkies think that
117
295260
2000
I, tot i que els jonquis creuen
04:57
it's a really bad idea to expose themselves to HIV,
118
297260
3000
que és molt mala idea exposar-se al VIH,
05:00
they think it's a much worse idea
119
300260
2000
creuen que és molt pitjor
05:02
to spend the next year in jail
120
302260
2000
passar el següent any a la presó,
05:04
where they'll probably end up in Frankie's situation
121
304260
2000
on segurament acabaran en la situació del Frankie
05:06
and expose themselves to HIV anyway.
122
306260
3000
i s'exposaran al VIH igualment.
05:09
So, suddenly it becomes perfectly rational
123
309260
2000
I, de sobte, sona perfectament racional
05:11
to share needles.
124
311260
2000
compartir les agulles.
05:13
Now, let's look at it from a policy maker's point of view.
125
313260
2000
Vegem què passa a l'hora de fer polítiques.
05:15
This is a really easy problem.
126
315260
2000
És un problema fàcil de resoldre.
05:17
For once, your incentives are aligned.
127
317260
3000
En això, tots tenim els mateixos interessos.
05:20
We've got what's rational for public health.
128
320260
3000
Una cosa que és racional en salut pública.
05:23
You want people to use clean needles --
129
323260
2000
Tu vols que la gent utilitzi agulles netes
05:25
and junkies want to use clean needles.
130
325260
2000
i els jonquis volen utilitzar agulles netes.
05:27
So we could make this problem go away
131
327260
2000
Per tant, podríem resoldre el problema
05:29
simply by making clean needles universally available
132
329260
3000
fent accessibles universalment les agulles netes
05:32
and taking away the fear of arrest.
133
332260
2000
i eliminant la por de l'arrest.
05:34
Now, the first person to figure that out
134
334260
2000
La primera persona que ho va pensar
05:36
and do something about it on a national scale
135
336260
2000
i que va fer alguna cosa a escala nacional
05:38
was that well-known, bleeding heart liberal
136
338260
3000
va ser aquesta popular i sentimetal liberal:
05:41
Margaret Thatcher.
137
341260
2000
Margaret Thatcher.
05:43
And she put in the world's first
138
343260
2000
Va posar en marxa el primer
05:45
national needle exchange program,
139
345260
2000
programa de distribució d'agulles del món
05:47
and other countries followed suit: Australia, The Netherlands and few others.
140
347260
3000
i altres països la van imitar, com Austràlia o Holanda.
05:50
And in all of those countries, you can see,
141
350260
2000
I podeu veure que en aquells països
05:52
not more than four percent of injectors
142
352260
2000
menys del 4% dels addictes
05:54
ever became infected with HIV.
143
354260
3000
es van infectar amb el VIH.
05:57
Now, places that didn't do this -- New York City for example,
144
357260
3000
En llocs que no ho van fer, com Nova York,
06:00
Moscow, Jakarta --
145
360260
2000
Moscou o Jakarta,
06:02
we're talking, at its peak,
146
362260
2000
veiem, en el seu punt màxim,
06:04
one in two injectors
147
364260
3000
que 1 de cada 2
06:07
infected with this fatal disease.
148
367260
3000
va contraure aquesta malaltia mortal.
06:10
Now, Margaret Thatcher didn't do this
149
370260
2000
Margaret Thatcher no ho va fer
06:12
because she has any great love for junkies.
150
372260
3000
pel seu gran amor pels jonquis.
06:15
She did it because she ran a country
151
375260
3000
Ho va fer perquè dirigia un país
06:18
that had a national health service.
152
378260
2000
amb un sistema de salut pública.
06:20
So, if she didn't invest in effective prevention,
153
380260
3000
I si no invertia en la prevenció efectiva
06:23
she was going to have pick up the costs
154
383260
2000
hauria d'assumir els costos
06:25
of treatment later on,
155
385260
2000
del tractament més tard,
06:27
and obviously those are much higher.
156
387260
2000
que eren molt més elevats.
06:29
So she was making a politically rational decision.
157
389260
3000
Va prendre una decisió políticament racional.
06:32
Now, if I take out my
158
392260
2000
Si ara em poso
06:34
public health nerd glasses here
159
394260
2000
les ulleres d'expert en salut pública
06:36
and look at these data,
160
396260
3000
i miro aquestes dades,
06:39
it seems like a no-brainer, doesn't it?
161
399260
3000
sembla una obvietat, no?
06:42
But in this country,
162
402260
2000
Però en aquest país,
06:44
where the government apparently does not feel compelled
163
404260
3000
on el govern no sembla que es consideri responsable
06:47
to provide health care for citizens, (Laughter)
164
407260
2000
d'oferir un servei de salut als ciutadans,
06:49
we've taken a very different approach.
165
409260
3000
hem escollit un altre camí.
06:52
So what we've been doing in the United States
166
412260
2000
El que hem fet als Estats Units
06:54
is reviewing the data -- endlessly reviewing the data.
167
414260
3000
és revisar les dades; fins a l'extenuació.
06:57
So, these are reviews of hundreds of studies
168
417260
3000
Això són informes de centenars d'estudis
07:00
by all the big muckety-mucks
169
420260
2000
de tots els mestretites
07:02
of the scientific pantheon in the United States,
170
422260
3000
del panteó científic dels Estats Units
07:05
and these are the studies that show
171
425260
2000
i aquests estudis demostren
07:07
needle programs are effective -- quite a lot of them.
172
427260
2000
que els programes d'agulles són efectius.
07:09
Now, the ones that show that needle programs aren't effective --
173
429260
3000
I els que demostren que no són efectius...
07:12
you think that's one of these annoying dynamic slides
174
432260
3000
Pensareu que és una d'aquelles estúpides
07:15
and I'm going to press my dongle and the rest of it's going to come up,
175
435260
2000
diapositives dinàmiques i que ara apareixerà la resta,
07:17
but no -- that's the whole slide.
176
437260
3000
però no; ja hi és tot.
07:20
(Laughter)
177
440260
2000
(Riures)
07:22
There is nothing on the other side.
178
442260
3000
No hi ha res a l'altra banda.
07:27
So, completely irrational,
179
447260
2000
Del tot irracional
07:29
you would think.
180
449260
2000
pensareu.
07:31
Except that, wait a minute, politicians are rational, too,
181
451260
3000
Però, un moment, els polítics també són racionals
07:34
and they're responding to what they think the voters want.
182
454260
3000
i responen al que creuen que volen els votants.
07:37
So what we see is that voters respond
183
457260
2000
I veiem que els votants responen
07:39
very well to things like this
184
459260
2000
molt bé a ajudar els nens
07:41
and not quite so well to things like this.
185
461260
3000
i no tant bé a ajudar els jonquis.
07:44
(Laughter)
186
464260
7000
(Riures)
07:51
So it becomes quite rational
187
471260
3000
Per això és prou racional
07:54
to deny services to injectors.
188
474260
3000
negar els serveis als jonquis.
07:57
Now let's talk about sex.
189
477260
2000
Parlem de sexe ara.
07:59
Are we any more rational about sex?
190
479260
3000
Som més racionals respecte al sexe?
08:02
Well, I'm not even going to address
191
482260
2000
No penso mencionar
08:04
the clearly irrational positions
192
484260
2000
les posicions clarament irracionals
08:06
of people like the Catholic Church,
193
486260
2000
de gent com l'Església Catòlica,
08:08
who think somehow that if you give out condoms,
194
488260
3000
que pensen que si proporciones condons
08:11
everyone's going to run out and have sex.
195
491260
4000
tothom correrà a practicar el sexe.
08:15
I don't know if Pope Benedict
196
495260
2000
No sé si el papa Benet
08:17
watches TEDTalks online,
197
497260
2000
mira TEDTalks,
08:19
but if you do, I've got news for you Benedict --
198
499260
3000
però si ho fas, et diré una cosa, Benet.
08:22
I carry condoms all the time
199
502260
3000
Sempre porto condons
08:25
and I never get laid.
200
505260
2000
i mai no tinc sexe.
08:27
(Laughter) (Applause)
201
507260
2000
(Riures i aplaudiments)
08:29
It's not that easy!
202
509260
2000
No és tan fàcil!
08:31
Here, maybe you'll have better luck.
203
511260
2000
Teniu. Potser vosaltres tindreu més sort.
08:33
(Applause)
204
513260
6000
(Aplaudiments)
08:39
Okay, seriously,
205
519260
2000
Bé, de debò,
08:41
HIV is actually not that easy
206
521260
3000
el VIH no és transment sexualment
08:44
to transmit sexually.
207
524260
2000
tan fàcilment.
08:46
So, it depends on how much virus there is
208
526260
2000
Depèn de quants virus hi ha
08:48
in your blood and in your body fluids.
209
528260
2000
a la teva sang i en els teus fluids.
08:50
And what we've got is a very, very high level of virus
210
530260
3000
Hi ha un nivell molt molt elevat de virus
08:53
right at the beginning when you're first infected,
211
533260
2000
al principi quan t'infectes per primer cop,
08:55
then you start making antibodies,
212
535260
2000
llavors fabriques anticossos
08:57
and then it bumps along at quite low levels
213
537260
2000
i es manté en nivells baixos
08:59
for a long time -- 10 or 12 years --
214
539260
2000
durant molt de temps, 10 o 12 anys,
09:01
you have spikes if you get another sexually transmitted infection.
215
541260
3000
hi ha alguna pujada si agafes una altra ITS.
09:04
But basically, nothing much is going on
216
544260
2000
Però, de fet, no passa gaire res
09:06
until you start to get symptomatic AIDS,
217
546260
2000
fins als símptomes de la SIDA,
09:08
and by that stage,
218
548260
2000
i a aquestes alçades
09:10
you're not looking great, you're not feeling great,
219
550260
2000
no fas bona cara, no et trobes genial i
09:12
you're not having that much sex.
220
552260
2000
no tens tant de sexe.
09:14
So the sexual transmission of HIV
221
554260
2000
La transmissió sexual del VIH
09:16
is essentially determined by how many partners you have
222
556260
3000
es determina principalment pel nombre de parelles
09:19
in these very short spaces of time
223
559260
3000
en aquests períodes breus
09:22
when you have peak viremia.
224
562260
2000
dels pics de virus a la sang.
09:24
Now, this makes people crazy
225
564260
3000
Aquí la gent s'ofèn
09:27
because it means that you have to talk about
226
567260
3000
perquè això porta a parlar
09:30
some groups having more sexual partners
227
570260
2000
d'alguns grups amb més parelles sexuals
09:32
in shorter spaces of time than other groups,
228
572260
2000
en menys temps que d'altres grups
09:34
and that's considered stigmatizing.
229
574260
2000
i això es considera estigmatitzant.
09:36
I've always been a bit curious about that
230
576260
2000
Sempre ho he trobat curiós
09:38
because I think stigma is a bad thing,
231
578260
2000
perquè crec que un estigma és dolent,
09:40
whereas lots of sex is quite a good thing,
232
580260
2000
mentre que tenir molt sexe és bastant bo,
09:42
but we'll leave that be.
233
582260
3000
però tant fa.
09:45
The truth is that 20 years
234
585260
2000
El cas és que 20 anys
09:47
of very good research
235
587260
2000
de recerca
09:49
have shown us that
236
589260
2000
demostren que
09:51
there are groups that are more likely to turnover
237
591260
3000
hi ha grups amb més tendència a tenir
09:54
large numbers of partners in a short space of time.
238
594260
2000
grans quantitats de parelles en poc temps.
09:56
And those groups are, globally,
239
596260
2000
Aquests grups són, principlament,
09:58
people who sell sex and their more regular partners.
240
598260
3000
els que venen sexe i les seves parelles habituals.
10:01
They are gay men on the party scene
241
601260
2000
Són gais de vida nocturna
10:03
who have, on average, three times more partners
242
603260
2000
que tenen el triple de parelles
10:05
than straight people on the party scene.
243
605260
2000
que els heteros de vida nocturna.
10:07
And they are heterosexuals
244
607260
2000
I són heterosexuals
10:09
who come from countries that have
245
609260
2000
de països amb tradició
10:11
traditions of polygamy
246
611260
2000
de poligàmia
10:13
and relatively high levels of female autonomy,
247
613260
3000
i nivells relativament alts d'autonomia femenina
10:16
and almost all of those countries are in east or southern Africa.
248
616260
3000
i quasi tots estan a l'est o al sud de l'Àfrica.
10:19
And that is reflected in the epidemic that we have today.
249
619260
3000
Això es reflecteix en l'epidèmia que hi ha avui.
10:22
You can see these horrifying figures from Africa.
250
622260
3000
Aquí teniu dades terribles de l'Àfrica.
10:25
These are all countries in southern Africa
251
625260
2000
Són països del sud de l'Àfrica
10:27
where between one in seven,
252
627260
2000
on entre 1/7
10:29
and one in three
253
629260
2000
i 1/3
10:31
of all adults,
254
631260
2000
dels adults
10:33
are infected with HIV.
255
633260
2000
tenen el VIH.
10:35
Now, in the rest of the world,
256
635260
2000
A la resta del món
10:37
we've got basically nothing going on in the general population --
257
637260
3000
quasi no passa res en la població general,
10:40
very, very low levels --
258
640260
2000
nivells molt baixos.
10:42
but we have extraordinarily high levels of HIV
259
642260
3000
Però hi ha nivells extraordinàriament alts
10:45
in these other populations who are at highest risk:
260
645260
3000
en les poblacions amb riscos més alts:
10:48
drug injectors, sex workers
261
648260
2000
drogoaddicció, prostitució
10:50
and gay men.
262
650260
2000
i homosexualitat.
10:52
And you'll note, that's the local data from Los Angeles:
263
652260
2000
Aquí teniu dades de Los Àngeles:
10:54
25 percent prevalence among gay men.
264
654260
3000
25% d'incidència entre gais.
10:58
Of course, you can't get HIV just by having unprotected sex.
265
658260
3000
I no pots agafar el VIH només fent sexe sense protecció.
11:01
You can only HIV by having unprotected sex
266
661260
3000
El pots agafar només si tens sexe sense protecció
11:04
with a positive person.
267
664260
3000
amb seropositius.
11:07
In most of the world,
268
667260
2000
En la major part del món,
11:09
these few prevention failures
269
669260
2000
malgrat aquests fracasos
11:11
notwithstanding,
270
671260
2000
de prevenció,
11:13
we are actually doing quite well these days
271
673260
2000
ho fem prou bé actualment
11:15
in commercial sex:
272
675260
2000
en el sexe comercial.
11:17
condom use rates are between 80 and 100 percent
273
677260
2000
El condó s'utilitza entre un 80 i un 100%
11:19
in commercial sex in most countries.
274
679260
3000
dels casos en la majoria de països.
11:22
And, again, it's because of an alignment of the incentives.
275
682260
3000
Això és, un altre cop, per interessos comuns.
11:25
What's rational for public health
276
685260
2000
El que és racional per a la salut pública
11:27
is also rational for individual sex workers
277
687260
2000
també ho és per als treballadors sexuals
11:29
because it's really bad for business to have another STI.
278
689260
3000
perquè és dolent per al negoci tenir una ITS.
11:32
No one wants it.
279
692260
2000
Ningú no ho vol.
11:34
And, actually, clients don't want to go home with a drip either.
280
694260
2000
Els clients no volen tornar a casa amb una malaltia.
11:36
So essentially, you're able to achieve
281
696260
3000
És a dir, es poden aconseguir
11:39
quite high rates of condom use in commercial sex.
282
699260
3000
índex alts d'ús de condons en el sexe comercial.
11:42
But in "intimate" relations
283
702260
2000
Però en les relacions <i>íntimes</i>
11:44
it's much more difficult because,
284
704260
2000
és molt més difícil perquè,
11:46
with your wife or your boyfriend
285
706260
2000
amb la teva dona o xicot
11:48
or someone that you hope might turn into one of those things,
286
708260
3000
o algú que creus que s'hi podria convertir,
11:51
we have this illusion of romance
287
711260
3000
tenim la il·lusió romàntica
11:54
and trust and intimacy,
288
714260
2000
de confiança i intimitat,
11:56
and nothing is quite so unromantic
289
716260
3000
però res és menys romàntic
11:59
as the, "My condom or yours, darling?" question.
290
719260
3000
que "El meu condó o el teu, amor?"
12:02
So in the face of that,
291
722260
3000
Davant d'això
12:05
you really need quite a strong incentive
292
725260
3000
cal un incentiu bastant fort
12:08
to use condoms.
293
728260
3000
per usar condons.
12:11
This, for example, this gentleman is called Joseph.
294
731260
3000
Per exemple, aquest home es diu Joseph.
12:14
He's from Haiti and he has AIDS.
295
734260
2000
És d'Haití i té la SIDA
12:16
And he's probably not having a lot of sex right now,
296
736260
3000
i segurament no té gaire sexe ara mateix,
12:19
but he is a reminder in the population,
297
739260
2000
però és un recordatori de
12:21
of why you might want to be
298
741260
2000
perquè podries voler
12:23
using condoms.
299
743260
2000
utilitzar condons.
12:25
This is also in Haiti and is a reminder
300
745260
2000
Això també és a Haití i és un recordatori
12:27
of why you might want to be having sex, perhaps.
301
747260
3000
de perquè podries voler tenir sexe, potser.
12:31
Now, funnily enough, this is also Joseph
302
751260
3000
Curiosament, també és el Joseph
12:34
after six months on antiretroviral treatment.
303
754260
3000
després de sis mesos de tractament antiretroviral.
12:38
Not for nothing do we call it the Lazarus Effect.
304
758260
3000
No li diuen l'efecte Llàtzer perquè sí.
12:43
But it is changing the equation
305
763260
3000
Però això canvia l'equació
12:46
of what's rational
306
766260
2000
del que és racional
12:48
in sexual decision-making.
307
768260
3000
en les decisions sexuals.
12:51
So, what we've got --
308
771260
2000
El cas és
12:53
some people say, "Oh, it doesn't matter very much
309
773260
2000
que alguns diuen: "No importa
12:55
because, actually, treatment is effective prevention
310
775260
3000
perquè el tractament ja és una previsió efectiva
12:58
because it lowers your viral load and therefore
311
778260
2000
perquè disminueix la càrrega viral i
13:00
makes it more difficult to transmit HIV."
312
780260
2000
dificulta la trasmissió del VIH."
13:02
So, if you look at the viremia thing again,
313
782260
3000
Si tornem a mirar la càrrega en sang,
13:05
if you do start treatment when you're sick,
314
785260
2000
si comences el tractament quan estàs malalt,
13:07
well, what happens? Your viral load comes down.
315
787260
3000
la càrrega viral disminueix.
13:10
But compared to what? What happens if you're not on treatment?
316
790260
3000
Comparat amb què? Què passa si no et tractes?
13:14
Well, you die,
317
794260
2000
Que mors,
13:16
so your viral load goes to zero.
318
796260
2000
i la càrrega viral baixa a zero.
13:18
And all of this green stuff here, including the spikes --
319
798260
3000
I tot això en verd, inclosos els pics,
13:21
which are because you couldn't get to the pharmacy,
320
801260
4000
que hi són perquè no vas poder anar a la farmàcia
13:25
or you ran out of drugs, or you went on a three day party binge
321
805260
3000
o et vas quedar sense medicaments o vas passar tres dies de festa
13:28
and forgot to take your drugs,
322
808260
2000
i te'n vas oblidar
13:30
or because you've started to get resistance, or whatever --
323
810260
3000
o perquè hi desenvolupes resistència o el que sigui...
13:33
all of that is virus
324
813260
2000
Tot és virus
13:35
that wouldn't be out there, except for treatment.
325
815260
3000
que no hi seria sense el tractament.
13:38
Now, am I saying, "Oh, well, great prevention strategy.
326
818260
3000
Per tant, "Gran estratègia de prevenció;
13:41
Let's just stop treating people."
327
821260
2000
deixem de tractar la gent."
13:43
Of course not, of course not.
328
823260
2000
No. És clar que no.
13:45
We need to expand antiretroviral treatment as much as we can.
329
825260
3000
Hem d'expandir el tractament tant com puguem.
13:48
But what I am doing is calling into question
330
828260
2000
El que faig és qüestionar
13:50
those people who say that more treatment
331
830260
2000
els que diuen que més tractament
13:52
is all the prevention we need.
332
832260
2000
és tota la prevenció que ens cal.
13:54
That's simply not necessarily true,
333
834260
3000
Això no és necessàriament cert
13:57
and I think we can learn a lot from the experience of gay men
334
837260
2000
i crec que podem aprendre molt dels gais
13:59
in rich countries where treatment has been widely available
335
839260
3000
de països rics on el tractament ha estat disponible
14:02
for going on 15 years now.
336
842260
2000
durant 15 anys ja.
14:04
And what we've seen is
337
844260
2000
El que veiem és
14:06
that, actually, condom use rates,
338
846260
2000
que l'índex d'ús de condons,
14:08
which were very, very high --
339
848260
2000
que eren molt molt alts
14:10
the gay community responded very rapidly to HIV,
340
850260
3000
-la comunitat gai va repondre ràpidament al VIH
14:13
with extremely little help
341
853260
2000
amb molt poca ajuda
14:15
from public health nerds, I would say --
342
855260
2000
de la salut pública, diria jo-
14:17
that condom use rate has come down dramatically since treatment
343
857260
3000
l'ús de condons ha disminuit dràsticament des que hi ha tractament
14:20
for two reasons really:
344
860260
2000
per dues raons.
14:22
One is the assumption of, "Oh well,
345
862260
2000
Una és la creença de
14:24
if he's infected, he's probably on meds,
346
864260
2000
"Si té el VIH, segurament es medica
14:26
and his viral load's going to be low, so I'm pretty safe."
347
866260
3000
i la càrrega viral és baixa i és prou segur."
14:29
And the other thing is that people are simply
348
869260
2000
D'altra banda, la gent ja no està
14:31
not as scared of HIV
349
871260
2000
espantada del VIH
14:33
as they were of AIDS, and rightly so.
350
873260
3000
com ho estava de la SIDA.
14:36
AIDS was a disfiguring disease that killed you,
351
876260
3000
La SIDA et desfigurava i et matava,
14:39
and HIV is an invisible virus
352
879260
2000
el VIH és un virus invisible
14:41
that makes you take a pill every day.
353
881260
2000
que et fa prendre una pastilla al dia.
14:43
And that's boring,
354
883260
2000
I fa mandra,
14:45
but is it as boring as
355
885260
3000
però en fa tanta com
14:48
having to use a condom every time you have sex,
356
888260
2000
fer servir un condó cada cop que tens sexe,
14:50
no matter how drunk you are,
357
890260
2000
encara que vagis begut,
14:52
no matter how many poppers you've taken, whatever?
358
892260
3000
encara que hagis pres poppers o el que sigui?
14:55
If we look at the data, we can see that
359
895260
2000
Mirant les dades, veurem que
14:57
the answer to that question
360
897260
2000
la resposta és
14:59
is, mmm.
361
899260
2000
"Mmm."
15:01
So these are data from Scotland.
362
901260
2000
Això són dades d'Escòcia.
15:03
You see the peak in drug injectors
363
903260
2000
Veieu el pic en drogoaddictes
15:05
before they started the national needle exchange program.
364
905260
2000
abans del programa d'agulles.
15:07
Then it came way down.
365
907260
2000
Llavors va baixar.
15:09
And both in heterosexuals -- mostly in commercial sex --
366
909260
2000
I tant en heteros, la majoria en sexe comercial,
15:11
and in drug users,
367
911260
2000
com en drogoaddictes
15:13
you've really got nothing much going on after treatment begins,
368
913260
3000
no hi ha gaire a fer quan ha començat el tractament
15:16
and that's because of that alignment of incentives
369
916260
2000
a causa dels interessos comuns
15:18
that I talked about earlier.
370
918260
2000
que hem dit abans.
15:20
But in gay men,
371
920260
2000
Però en els gais
15:22
you've got quite a dramatic rise
372
922260
2000
hi ha un increment dràstic
15:24
starting three or four years
373
924260
2000
3 o 4 anys després
15:26
after treatment became widely available.
374
926260
2000
que el tractament es fes accessible.
15:28
This is of new infections.
375
928260
2000
Això són infeccions noves.
15:30
What does that mean?
376
930260
2000
Què vol dir?
15:32
It means that the combined effect of being less worried
377
932260
3000
Que l'efecte combinat de menys preocupació
15:35
and having more virus out there in the population --
378
935260
3000
i d'haver-hi més virus entre la població,
15:38
more people living longer, healthier lives,
379
938260
2000
que viuen vides sanes més anys i
15:40
more likely to be getting laid
380
940260
2000
probablement tindran sexe
15:42
with HIV --
381
942260
2000
amb el VIH,
15:44
is outweighing the effects of lower viral load,
382
944260
3000
sobrepassa els efectes de la baixa càrrega viral
15:47
and that's a very worrisome thing.
383
947260
2000
i això és molt preocupant.
15:49
What does it mean?
384
949260
2000
Què vol dir?
15:51
It means we need to be doing more prevention the more treatment we have.
385
951260
3000
Que hem de fer més prevenció com més tractament tinguem.
15:54
Is that what's happening?
386
954260
2000
I això ho fem?
15:56
No, and I call it the "compassion conundrum."
387
956260
3000
No. Ho anomeno l'<i>enigma de la compassió</i>.
15:59
We've talked a lot about compassion the last couple of days,
388
959260
3000
Hem parlat de compassió els últims dies,
16:02
and what's happening really is that people are
389
962260
3000
però en realitat la gent
16:05
unable quite to bring themselves to put in
390
965260
2000
és incapaç d'aconseguir
16:07
good sexual and reproductive health services for sex workers,
391
967260
3000
bons serveis de salut per a treballadors sexuals
16:10
unable quite to be giving out needles to junkies.
392
970260
3000
o de donar agulles als jonquis.
16:13
But once they've gone from being
393
973260
3000
Però quan han passat
16:16
transgressive people whose behaviors we don't want to condone
394
976260
3000
de ser trangressors amb conductes inacceptables
16:19
to being AIDS victims,
395
979260
2000
a víctimes de la SIDA,
16:21
we come over all compassionate
396
981260
2000
ens tornem compassius
16:23
and buy them incredibly expensive drugs for the rest of their lives.
397
983260
2000
i els paguem medicines increïblement cares per tota la vida.
16:25
It doesn't make any sense
398
985260
2000
No té cap sentit
16:27
from a public health point of view.
399
987260
2000
des del punt de vista de la salut pública.
16:29
I want to give what's very nearly the last word to Ines.
400
989260
4000
Quasi per acabar parlaré de la Ines.
16:33
Ines is a a transgender hooker on the streets of Jakarta;
401
993260
3000
Ella és una puta transexual de Jakarta;
16:36
she's a chick with a dick.
402
996260
2000
una noia amb polla.
16:38
Why does she do that job?
403
998260
2000
Per què fa aquesta feina?
16:40
Well, of course, because she's forced into it
404
1000260
3000
Perquè hi està obligada, és clar.
16:43
because she doesn't have any better option, etc., etc.
405
1003260
2000
Perquè no té cap alternativa, etc.
16:45
And if we could just teach her to sew
406
1005260
2000
Si li poguéssim ensenyar a cosir
16:47
and get her a nice job in a factory, all would be well.
407
1007260
3000
i donar-li feina en una fàbrica, estaria bé.
16:50
This is what factory workers earn in an hour in Indonesia:
408
1010260
2000
Els treballadors d'una fàbrica a Indonèsia guanyen
16:52
on average, 20 cents.
409
1012260
2000
uns 0,20 €/h.
16:54
It varies a bit province to province.
410
1014260
2000
Canvia un xic entre províncies.
16:56
I do speak to sex workers, 15,000 of them
411
1016260
3000
Parlant amb treballadors sexuals,
16:59
for this particular slide,
412
1019260
2000
15.000 en aquest cas,
17:01
and this is what sex workers
413
1021260
2000
això és el que diuen
17:03
say they earn in an hour.
414
1023260
2000
que guanyen en una hora.
17:05
So it's not a great job, but for a lot of people
415
1025260
3000
No és una gran feina, però
17:08
it really is quite a rational choice.
416
1028260
2000
és una escolla ben racional.
17:10
Okay, Ines.
417
1030260
2000
Vegeu l'Ines.
17:15
We've got the tools, the knowledge and the cash,
418
1035260
5000
Tenim les eines, el coneixement, els diners i
17:20
and commitment to preventing HIV too.
419
1040260
4000
el compromís a prevenir el VIH.
17:24
Ines: So why is prevalence still rising?
420
1044260
6000
I per què augmenten les infeccions?
17:30
It's all politics.
421
1050260
3000
Política.
17:33
When you get to politics, nothing makes sense.
422
1053260
3000
En política, res no té sentit.
17:36
Elizabeth Pisani: "When you get to politics, nothing makes sense."
423
1056260
3000
Diu: "En política, res no té sentit."
17:39
So, from the point of view of a sex worker,
424
1059260
3000
Per a un treballador sexual
17:42
politicians are making no sense.
425
1062260
2000
la política no té sentit.
17:44
From the point of view of a public health nerd,
426
1064260
2000
Per a un entès en salut pública
17:46
junkies are doing dumb things.
427
1066260
3000
els jonquis fan estupideses.
17:50
The truth is that everyone has a different rationale.
428
1070260
3000
Tothom té un concepte diferent de <i>racional</i>.
17:53
There are as many different ways of being rational
429
1073260
2000
Hi ha tants conceptes diferents
17:55
as there are human beings on the planet,
430
1075260
2000
com humans hi ha al planeta,
17:57
and that's one of the glories of human existence.
431
1077260
2000
i aquesta és una de les meravelles dels éssers humans.
17:59
But those ways of being rational
432
1079260
2000
Però cap d'aquests conceptes
18:01
are not independent of one another,
433
1081260
2000
és independent dels altres.
18:03
so it's rational for
434
1083260
2000
Compartir és racional
18:05
a drug injector to share needles
435
1085260
2000
per a un drogoadicte
18:07
because of a stupid decision that's made by a politician,
436
1087260
3000
per la decisió estúpida d'un polític,
18:10
and it's rational for a politician
437
1090260
2000
i per al polític és racional
18:12
to make that stupid decision
438
1092260
3000
aquesta decisió estúpida
18:15
because they're responding to
439
1095260
2000
perquè respon al que
18:17
what they think the voters want.
440
1097260
2000
creu que els votants volen.
18:19
But here's the thing:
441
1099260
2000
El cas és que
18:21
we are the voters.
442
1101260
2000
nosaltres som els votants.
18:23
We're not all of them, of course, but TED is a community of opinion leaders.
443
1103260
3000
No tot ells, però a TED som un model d'opinió.
18:26
And everyone who's in this room,
444
1106260
2000
Tots els d'aquesta sala
18:28
and everyone who's watching this out there on the web,
445
1108260
3000
i tots els que ens veuen per Internet
18:31
I think, has a duty to demand of their politicians
446
1111260
3000
tenim el deure d'exigir als polítics
18:34
that we make policy based on scientific evidence
447
1114260
3000
que es basin en les dades científiques
18:37
and on common sense.
448
1117260
2000
i en el sentit comú.
18:39
It's going to be really hard for us
449
1119260
2000
És molt difícil que individualment
18:41
to individually affect what's rational
450
1121260
3000
canviem el que és racional
18:44
for every Frankie and every Ines out there,
451
1124260
2000
per a cada Frankie i Ines,
18:46
but you can at least use your vote
452
1126260
3000
però podem fer servir el vot
18:49
to stop politicians doing stupid things
453
1129260
3000
per evitar les polítiques estúpides
18:52
that spread HIV.
454
1132260
2000
que escampen el VIH.
18:54
Thank you.
455
1134260
2000
Gràcies.
18:56
(Applause)
