Sala1987-an, bi deh hezaran mirov
00:09
gathered in Saudi Arabia for the annual Hajj pilgrimage.
1
9827
4430
li Erebistana Saudî ji bo ‏hec a salane civiyan.
00:14
But what started out as a celebration led to a health crisis:
2
14257
4290
‏lê ya ku wekî pîrozîyek ê dest pê kir ‏bû sedema krîzek tenduristiyê:
00:18
just a few days after the pilgrimage,
3
18547
2201
çend rojan piştî hecê,
00:20
more than 2,000 cases of meningitis broke out
4
20748
4070
zêdeyî 2000 bûyerên menenjîtê ( mejûtevn) derketin
00:24
spreading across Saudi Arabia and the rest of the world.
5
24818
3280
li seranserê Erebistana Saûdî ‏û yên dinê belav bû.
00:28
The outbreak was so fierce
6
28098
2190
Epîdemî ( peta) pir dijwar bû
00:30
that it was believed to have sparked a wave of deadly meningitis epidemics
7
30288
4469
ku dihat bawer kirin ku çirûskek a pêla epîdemiyên meningîta kujer e
00:34
that ultimately infected tens of thousands of people worldwide.
8
34757
4200
ku di dawîyê de bi dehan vegirtî bi hezaran mirovên cîhanê.
00:40
Meningitis is the inflammation of the meninges,
9
40197
3140
Meningitis alyana meninge ye,
00:43
three tissue layers responsible for protecting the brain and spinal cord.

sê tebeqên tevnê ku berpirsiyar in li parastin a mejî û mejîyê pişt ê.
00:48
What makes meningitis so dangerous compared to other diseases
11
48297
3730
Ya ku menenjîtê li gorî nexweşiyên din ew qas metirsîdar dike
00:52
is the sheer speed with which it invades a person’s body.
12
52027
4060
leza berçav e ku ew laşê kesan dagîr dike.
00:56
In the worst cases, it causes death within a day.
13
56087
3790
Di rewşa herî xirab de, dibe sedema mirinê di rojê de.
00:59
Fortunately, that’s rare for patients who receive early medical treatment.
14
59877
4900
Bi kêfxweşî, ew ji bo nexweşên ku zû dermankirin a bijîşkî digirin kêm e.
01:04
The disease primarily comes in three forms:
15
64777
3200
Nexweşî di destpêkê de bi sê awayan tê:
01:07
fungal, viral, and bacterial-- the last being the most deadly by far,
16
67977
4880
kuvarik, vîrusî, û bakteriyalî - ya herî dawî ya herî mirinê heya niha,
01:12
and what we’ll focus on.
17
72857
2160
û em ê li ser çi bisekinin.
01:15
People usually contract bacterial meningitis by breathing in
18
75017
3480
Mirov bi gelemperî bi nefes girtinê bi menenjîta bakterî dikevin
01:18
tiny particles of mucus and saliva that spray into the air
19
78497
4300
piçikên piçûk ên kilîz ê û devûyê ku li hewa diherikin
01:22
when an infected person sneezes or coughs.
20
82797
3340
Demê kesê nesax Di bêhnije yan di kuxe.
01:26
It can also be transmitted through kissing,
21
86137
2320
Herwiha di hête vexguhastin Bi rêya maçkirinê,
01:28
or sharing cigarettes, toothbrushes or utensils.
22
88457
4020
an hevbeşkirina cigaran, Firçên didan şûştinê an alavan,
01:32
Some people can be infected and carry the disease
23
92477
2780
dibe ku hindek kes nesaxbibin û bibin helgirê nesaxîyê
01:35
without showing symptoms or getting sick,
24
95257
2880
Bê nîşandan a berjengan anku nesaxketin ê,
01:38
which helps the disease spread quickly to others.
25
98137
3840
ku dibe alîkar ku nexweşî bilez li yên din belav bibe.
01:41
Once the bacteria enter the nose, mouth, and throat,
26
101977
3190
Carek bakterî dikevin poz, dev û qirik,
01:45
they cross the surrounding membranes and enter the bloodstream.
27
105167
3670
ew derdor a çermikî derbas dikin û dikevin nav xwînê.
01:48
From there, bacteria have rapid access to the body’s tissues
28
108837
4360
li wir, bakterî zû di gihîjin şaneyên laş
01:53
--including a membrane called the blood-brain barrier.
29
113197
3590
- tê de mebesta ku jê re astengiya xwîn-mejî tê gotin.
01:56
This is made of a tight mesh of cells which separate blood vessels from the brain,
30
116787
5130
ev ji tevnek teng a şaneyên ku rehên xwînê ji mejî veqetînin,
02:01
and block everything except for a specific set of particles,
31
121917
3900
û ji bilî komek perçeyên taybet, her tiştî asteng bikin,
02:05
including water molecules and some gases.
32
125817
3280
Piçikên avê û hindek gaz jî tê de.
02:09
But in ways that scientists are still trying to understand,
33
129097
3270
Lê bi awayên ku zanyar hîn jî hewl didin fam bikin,
02:12
meningitis bacteria can trick the barrier into letting them through.
34
132367
4790
Bakteriyên meningîtê dikarin astengiyê derxînin da ku ew derbas bibin.
02:17
Inside the brain, the bacteria swiftly infect the meninges.
35
137157
3880
dinav mejî de, Bektirya bilez menenjîtê ( mejûtevn) nesax dike.
02:21
This triggers inflammation as the body’s immune response kicks into overdrive,
36
141037
4980
Ev wekî laş iîltihaba di arîne bersiva parastn ê dikeve nav westandinê de.
02:26
bringing on fever and intense headaches.
37
146017
3190
ta û serêşên dijwar tînin.
02:29
As swelling in the meninges worsens, the neck begins to stiffen.
38
149207
3980
her ku werimandin a di mênteng ê de xirab dibe, stu dest bi hişkbûnê dike.
02:33
Swelling in the brain disrupts its normal function--
39
153187
2620
di mejî de werimandin karê wîyê asayî têk dide-
02:35
causing symptoms like hearing loss and extreme light sensitivity.
40
155807
4510
dibe sedema nîşanên mîna bihîstinê û hestiyariya ronahiya giran.
02:40
As pressure increases in the cranium, it may also make the person confused--
41
160317
4850
Her ku di kiloxî de zext zêde dibe, dibe ku ew mirovî tevlihev jî bike-
02:45
one of the hallmarks of the disease.
42
165167
2720
Yek ji nîşanên vê nesaxîyê.
02:47
A few hours in, the rapidly multiplying bacteria start to release toxins,
43
167887
5020
Çend demjimêr di, bakteriyên bi lez zêde dibin dest bi berdana toksînan dikin,
02:52
leading to septicemia, also known as blood poisoning.
44
172907
4330
dibe sedema septicemia, wekî jehrîna xwînê jî tê zanîn.
02:57
This breaks down blood vessels,
45
177237
2190
ev rihên xwînê xirab dike,
02:59
letting blood seep out and form what starts out looking like a rash,
46
179427
4350
bila xwîn derkeve û tiştê ku dest pê dike mîna xirpûkek çêbike,
03:03
and evolves into big discoloured blots beneath the skin.
47
183777
4320
û li binê çerm de pelikên mezin ên ‏bêreng pêş dikevin.
03:08
At the same time, these toxins burn through oxygen in the blood,
48
188097
4140
Di heman demê de, ev jehr bi oksîjena xwînê dişewitin,
03:12
reducing the amount that gets to major organs like the lungs and kidneys.
49
192237
5130
kêm kirina jimarên ku digihîjin organên sereke mîna pişik û gurçikan.
03:17
That increases the chance of organ shut down
50
197367
3230
Ew şansê girtina organê zêde dike
03:20
--and alongside spreading septicemia, threatens death.
51
200597
4180
- û digel belavkirina jehrîbûn a xwînê, gefên mirinê dike.
03:24
That all sounds scary, but doctors are so good at treating meningitis
52
204777
4400
Ew hemî tirsnak xuya dike, lê bijîşk di derman kirina meningîtê de ew qas jêhatî ne
03:29
that a visit to the hospital can drastically reduce an adult’s risk of dying from it.
53
209177
5300
ku serdana nexweşxaneyê dikare talûke ya mirinê li mezinan bi tundî kêm bike.
03:34
The longer it’s left untreated, though,
54
214477
2070
Çiqas dirêjtir bibe nayê dermankirin, tevî ku,
03:36
the more likely it will lead to lasting damage.
55
216547
2910
bi pêkaneke mezin ew ê bibe sedema zirarek mayînde.
03:39
If declining oxygen levels cause cell death in extreme parts of the body
56
219457
4510
Ger kêmbûna asta oksîjenê dibe sedema mirina şaneyên li deverên tund ên laş
03:43
--like fingers, toes, arms and legs-- the risk of amputation goes up.
57
223967
5210
mîna tilîyên desta, tilîyên pê, dest û ling - metirsiya jêkirinê zêde dibe.
03:49
And if bacterial toxins accumulate in the brain and trigger cell death,
58
229177
4890
û heke jehrên bakteriyel di mejî de kom bibin û mirina xaneyê pêk bînin,
03:54
meningitis could also cause long-term brain damage and memory loss.
59
234067
4580
menenjît dikare di heman demê de bibe sedema
xisara mêjî ya demdirêj û windakirina bîrewerîyan.
03:58
So fast treatment, or better yet, prevention, is critical.
60
238647
4600
Ji ber vê yekê dermankirina bilez, an hê çêtir, pêşîlêgirtin, girîng e.
04:03
That's why most countries have vaccines that defend against the disease
61
243247
4120
Loma li piraniya welatan derziyên ku li dijî nexweşîyê diparêzin hene
04:07
in its deadliest forms.
62
247367
1850
di teşeyên xweyên kujer de.
04:09
Those are usually given to the people who are most at risk--like young children,
63
249217
4290
Ew bi gelemperî ji mirovên ku herî zêde di xetereyê de ne têne dayîn, mîna: zarokên piçûk,
04:13
people with weak immune systems, or people who gather in large groups
64
253507
4100
mirovên xwedan pergalên parastinê yên lawaz, an kesên ku di komên mezin de kom dibin
04:17
where an outbreak of meningitis could potentially happen.
65
257607
3960
li ku dibe ku şewba kulbûna ‏perdeya mejîyî pêk were.
04:21
In addition to those gatherings,
66
261567
1580
Ji bilî wan kom bûnan,
04:23
meningitis is most common in a region called the meningitis belt
67
263147
3970
menenjît herî zêde li herêmek ku jê re qayişa menenjît tê gotin
04:27
that stretches across Africa, though cases do happen all over the world.
68
267117
5070
ku li seranserê Afrîkayê dirêj dibe, her çend rewş li her devera cîhanê diqewimin.
04:32
If you’re concerned that you or someone you know may have meningitis,
69
272187
3520
Heke hûn xemgîn in ku hûn an kesek hûn dizanin ku dibe ku menenjît hebe,
04:35
get to the doctor as soon as possible;
70
275707
2550
Bilez xwe bigehînin doktor gava çêbibît;
04:38
quick action could save your life.
71
278257
3430
çalakiyeke bilez dikare jiyana we rizgar bike.
