Containment Procedures SCP-129

0:25

is at large in the

0:28

world and infects large numbers

0:30

of humans and animals daily.

0:33

As such, containment efforts are

0:35

focused on treatment of infected

0:37

individuals and on eradication of

0:39

any or all member species

0:41

of SCP-129. Although

0:44

at least 98% of

0:47

the world's population harbors a

0:49

natural immunity to one or

0:51

more species of SCP-129, outbreaks

0:54

that reach Stage 3

0:56

or higher, described below,

0:59

must be contained as

1:01

quickly as possible, with

1:03

infected individuals quarantined under

1:06

highest-risk contagion protocols. See

1:08

Document Number 129A1 for further information.

1:13

In the event of Stage 4

1:16

or Stage 5 outbreak, in addition

1:18

to the above procedures, as described

1:25

in Document Number 129A2, Level 4 Clearance Required. Description

1:32

SCP-129 is a series of

1:34

at least different species

1:40

of fungus that can

1:42

infect any animal with

1:44

mucosal membranes. Infection

1:47

by SCP-129 can pass

1:49

through up to five

1:51

stages, depending on exposure

1:53

to further member species

1:56

of SCP-129, individual resistance,

1:58

and other factors. with

2:00

each stage of infection

2:02

facilitating progression to the

2:05

next stage by weakening

2:07

the individual's resistance to

2:09

subsequent infection. Due

2:11

to a combination of historical

2:14

events, most humans and

2:16

animals are naturally immune to

2:18

SCP-129-04 through SCP-129- Therefore,

2:26

outbreaks of stage 3

2:28

infections are quite rare,

2:30

but have the potential

2:32

for widespread infection if

2:35

not swiftly isolated and

2:37

contained. All known

2:39

cases of SCP-129 have

2:41

followed the below 5-stage

2:44

progression, although data

2:46

expunged, possibly

2:49

due to mutation. Stage

2:52

1 The first

2:55

organism, SCP-129-01, attacks

2:58

the victim's mucosal

3:00

membranes, multiplying quickly

3:03

and unobtrusively. A

3:06

faint, yeast-like smell might be

3:09

detected, but beyond that, SCP-129-01

3:11

is asymptomatic. A

3:17

second organism, SCP-129-02, can

3:19

then infect the host,

3:22

causing the victim to

3:24

experience symptoms identical to

3:27

those of acute viral

3:30

nasopharyngitis, the common cold.

3:33

The decreased efficacy of the host's immune

3:35

system due to infection from SCP-129-02

3:37

allows SCP-129-01 to become entrenched further.

3:46

SCP-129-01 and SCP-102 generally leave the host

3:49

body within 4-6 days, though both species

3:51

are fairly widespread, and

4:00

most of the population has

4:02

little to no protection against

4:04

either organism. They pose

4:06

little danger themselves, except

4:08

to facilitate infection by

4:10

SCP-129-03. Stage

4:16

2. Although

4:19

SCP-129-03 is usually stopped

4:21

by natural mucus, stage

4:23

1 infection changes the

4:25

composition of the host's

4:27

mucus so that the

4:30

host is significantly less

4:32

resistant to SCP-129-03. Once

4:37

established in the host, SCP-129-03

4:39

alters the host's mucus, lymph,

4:42

and blood such that other

4:44

species of SCP-129 can thrive

4:47

in the host. Symptoms

4:53

of Stage 2 infection

4:55

include greatly increased mucus

4:57

production, a nagging cough

4:59

due to excess phlegm,

5:01

a lingering low-grade fever,

5:04

increased sweating and salivating,

5:07

a somewhat increased preference

5:09

for vegetables, and the

5:12

complaint that certain fruit

5:14

juices taste odd. Infection

5:17

by SCP-129-03 generally lasts

5:19

anywhere from 2 weeks

5:21

to 4 months before

5:24

being driven out by

5:26

the immune system unless

5:28

the host enters Stage

5:30

3 infection. At

5:32

least, protected. Percent of

5:35

all humans have experienced Stage

5:37

2 infection at some point,

5:39

but due to natural immunities

5:41

in spite of Stage 2

5:43

infection and the relative rarity

5:46

of Stage 3 species less

5:48

than protected, percent of

5:50

that protected percent have

5:52

passed into Stage 3.

5:57

Stage 3. In the absence of the

6:00

Since of SCP-129-03,

6:02

nearly all animals are immune

6:04

to the three species that

6:07

cause stage 3 infection.

6:10

However, a small number of

6:12

stage 2 victims can become

6:14

infected with one or more

6:16

of these species. In

6:18

these cases, the fungal infections

6:21

become entrenched in the host

6:23

and cannot be removed without

6:25

extraordinary measures. Individually,

6:28

the three stage 3

6:30

species elicit different symptoms

6:32

in the host. SCP-129-04

6:36

causes increased

6:38

tear production,

6:40

lacrimation, slight

6:42

yellowing of the eyes, go

6:45

to expunged. SCP-129-05,

6:48

go to expunged. Pausing

6:54

the host's nails to thicken

6:56

and significantly increasing

6:58

earwax production. And

7:01

SCP-129-06, go to expunged. In

7:08

particular, bright yellow urine and

7:11

small pellets in the host's

7:13

feces, both of which smell

7:16

strongly of yeast. However,

7:19

a victim who becomes infected

7:21

with all three of these

7:23

species will, within hours, develop

7:26

flu-like or worse symptoms and

7:28

become bedridden for 3 to

7:30

5 weeks. Afterward,

7:34

though the victim appears to

7:36

have recovered fully, in actuality,

7:39

SCP-129 has spread

7:42

throughout all systems in

7:44

the host's body, marking passage

7:46

into stage 4. Stage

to a cave several kilometers

from town. Inside,

11:27

investigators found several pulsating

mounds of flesh and

11:32

vegetative material. Although

11:35

most were unrecognizable, a few

11:37

of the entities retained some

11:40

human characteristics and were identified

11:42

as some of the missing

11:45

citizens. Researchers

11:47

theorize that victims of

11:49

this combination of

11:52

SCP-129 would interact normally with

11:54

the populace, attempting

11:56

to infect others until

11:59

after... period of time,

12:01

they would come to the

12:03

cave. How and why they were

12:05

brought here is not known.

12:08

Upon arrival, the victims would

12:11

be changed into the pulsating

12:13

vegetative flesh mounds, which appear

12:15

to be organisms modified to

12:18

provide a long-term source of

12:20

sustenance for SCP-129.

Analysis suggests the flesh mounds could potentially

live for the blood of the body.
