Item #: SCP-####

Object Class: Euclid

Threat Level: Yellow

Special Containment Procedures: Study of SCP-####-1 is to be conducted to determine an effective means of removal at all stages of infection without terminating the host. To that end, instances of SCP-####-2 are to be accessible to level 2 researchers with approval and oversight of one level 3 researcher per study. Instances of SCP-####-2 found uncontained are to be retrieved for containment and use in research.

Instances of SCP-####-3 are to be contained as soon as possible. The Foundation’s MedCrawler program will continuously check new medical record information indicating both cardiovascular complaints and high eosinophil counts; flagged records will be reviewed by medical personnel under the Foundation front company Asclepius Health Investigators. Suspected instances of SCP-####-3will be quarantined and examined for infection by SCP-####. Confirmed instances of SCP-####-3 will be taken into Foundation custody, treated, and monitored for survival. All bodily fluids are to be contained and sterilized unless used for testing. Surviving instances of SCP-####-3 showing no presence of infection are to be considered non-anomalous and treated with Class C amnestics and released. The remains of non-surviving SCP-####-3 are to be incinerated.

Description: SCP-#### defines a parasitic infection targeting the human cardiovascular system. The parasite (henceforth SCP-####-1) outwardly resembles a member of the family Nematoda, despite DNA analysis revealing significant portions of human genetic material and several sequences displaying anomalous nucleotides.

SCP-####-2 is a 50 mg sugar tablet in the likeness of a ███████-brand painkiller. Testing of one tablet reveals hundreds of SCP-####-1 eggs encased within the tablet. The eggs are inert and do not activate unless exposed to a highly acidic environment. When the pill is swallowed, the eggs of SCP-####-1 detach as the sugar is dissolved and hatch into juvenile SCP-####-1. These instances are absorbed into the bloodstream, where they release targeted immunosuppressant chemicals which cause the immune system to fail to respond to them.1 At this point the individual who took the pill becomes an instance of SCP-####-3.

Infection by SCP-####-1 follows a prescribed course. Juvenile SCP-####-1 attach to junctions of larger blood vessels and capillaries and begin to consume the capillary tissues. During this process, the mouthparts remain attached to the capillary, and a metamorphosis occurs which shifts the tissues of SCP-####-1 to resemble a capillary. The feeding continues until the entire capillary is consumed, with its function being entirely replaced by SCP-####-1. Embedded instances will then feed on red blood cells and platelets to sustain themselves. While no longer motile, reproduction is possible via sperm packets sent by male specimens through the bloodstream to female specimens, allowing for fertilization of eggs.2 Further instances will seek out unconsumed capillaries and repeat the process. Juveniles that fail to attach to a capillary may be cannibalized by embedded SCP-####-1. Testing has not demonstrated the presence of SCP-####-1 in excreted bodily fluids; nevertheless, as the possibility has not been disconfirmed, fluids of SCP-####-3 are to be treated as infested.

SCP-####-1 is an imperfect replacement for capillaries, having similar but reduced permeability and occasionally triggering immune responses in the bloodstream, which often target other tissues instead of SCP-####-1. All cases of infection are at increased risk of blood clots through inefficient transfer of blood through SCP-####-1 and hemorrhage if SCP-####-1 is detached in sufficient quantities.3 Advanced cases may also see the development of anemia or hemophilia due to the overconsumption of red blood cells and platelets. These risks increase with greater presence of SCP-####-1 in the circulatory system, resulting in a high risk of premature death.

At an as-yet undetermined point in time subsequent to infection,4 the immune suppressant characteristics of SCP-####-1 begin to fail. This produces elevated eosinophil count in SCP-####-3 and contributes to acute cardiovascular complaints, including myocardial and vascular inflammation which have a high risk of fatality within 10 days of onset.

Antiparasitic medications are highly effective at killing SCP-####-1 at any point during infection. However, in advanced cases, this also leads to catastrophic and irreversible disruption of the cardiovascular system in SCP-####-3, resulting in rapid exsanguination and death. Testing with rodent models suggests no more than 30% saturation is necessary to create a mortality rate of 50%. Research is ongoing to determine the average time course for the spread of infestation to this degree and the factors which may promote or inhibit the spread of SCP-####-1.

History: SCP-#### was first identified at ████ █████ Hospital in ███████, ██ on 25/5/2009. A local political figure, ██████ ███████, entered the hospital complaining of symptoms suggesting cardiac disturbance. Routine testing determined the presence of a high eosinophil count, a typical indicator of parasitic infection, and Mr. ███████ was put on an antiparasitic treatment as a precaution. According to reports from medical staff, Mr. ███████ experienced massive internal hemorrhaging within 15 minutes of treatment.

Hospital officials contacted Asclepius Health Investigators,5 with reports of an unknown and potentially dangerous condition. Agents quarantined the remains of Mr. ███████ and brought them in for examination. Examination of blood samples revealed the presence of copious deceased SCP-NYA31-1, which were subsequently confirmed anomalous through genetic testing. The exact nature of SCP-####-1 was unknown at this point in time.

Investigation into Mr. ███████’s background within the past year indicated they had been championing a secure health initiative to crack down on unlicensed pharmaceuticals and biotech treatments which had not been properly tested. Analysis of electronic communications revealed multiple contacts from a publicly defunct corporate entity, Merkator Biolabs, which had been the subject of public reports of fraud and malpractice subsequent to dissolution in 2002 and whose known corporate head, Andruis Killearn and Mostav Petrovskias, were wanted on numerous criminal charges. Recovered communications could not be traced, and contents were nonspecifically threatening.

Investigating agents examining potential sites of unlicensed pharmaceutical activity raided a storage facility in ███████ on 3/6/2009. The interior of the unit had been converted into a makeshift laboratory and living facility, and appeared to have been abandoned within days of discovery. Multiple pharmaceutical objects and related documentation were recovered from the facility, including instances of what was later determined to be SCP-####-2 in a sealed container. Other recovered objects are currently undergoing testing for anomalous properties. Association with Merkator Biolabs was confirmed upon review of documentation pertinent to SCP-####.

Addendum ####-1: Recovered documentation

The following excerpts were found in proximity to the recovered instances of SCP-####-2. These personal notations were interspersed with experiment logs and data presumed to be during development of SCP-####-1. Examination of other logs shows similar notations, and dates suggest multiple experiments were being conducted concurrently.

Apparently I’m supposed to write down my ‘thoughts and ideas’ while I’m working on these projects? I still don’t really understand it, they said they wanted ‘ideas people’ working for them. I guess a Ph.D in microbiology isn’t enough. Then again, it obviously wasn’t enough for the last dozen places I applied to. At least I’m getting a chance here.

You guys want my thoughts, here’s one: I feel like you could do better than holing me up in a fucking storage unit. I’m supposed to work AND live here? Not only is that unsafe, it’s an awful place to live. Too bad it’s going to be a year before you see this.

I don’t know if I should be worried about my boss telling me I’m supposed to come up with a pill that’s an undetectable murder weapon. What kind of test project is that? The other two feel a lot less creepy…maybe it’s just this dude. I don’t even know what kind of accent that was. But whatever. It’s a roof over my head and money for meals. And if I succeed, I’m supposed to hit it pretty big. I could use that, what with student loans and all. I hope it comes before my deferments end.

What about a parasite?

They said poison’s out, which I guess makes sense, that would be too simple. But you couldn’t prove a parasite was on a pill. Or in it. I guess the only thing is that you had to make sure it would actually kill, since a lot of those can be treated. But it’s something.

Wait, hold on. I remember this old horror story I read back in college, some guy whose veins were there gruesome worms that would pop out of his body and eat people. Maybe I could do something along those lines?

Well, he loved the idea, which…I guess is good? Still creepy, but good. But how the hell am I actually supposed to MAKE something that does that? How does one MAKE a worm, anyway?

Okay, these people are still kinda weird, but that is some amazing tech they have. I probably should have realized it was simpler than I was making it out to be. Everything’s done with computers and technology, why not bioengineering? I guess what else would you use for that? Too bad it’s not something I can bring back with me, but that machine wouldn’t even fit in my hole in the wall.

I think I need to turn these things INTO replacement blood vessels. They aren’t doing anything as they are.

I don’t know how, but the metamorphosis works. I’m not even sure what’s in this DNA profile that thing spit out. Still, that’s one of the coolest things I think I’ve ever seen.

As weird as it is, I’m starting to like these little capillary worms I made. Even if they were for a ‘kill someone’ project. Which I still need to actually figure out how to make sure that happens, but whatever. I made something amazing, probably did something a lot more notable than anything in those other labs. Guess it’s true that one door closes, another opens. With these and the other two, I think I could come through my trial year as a winner.

I think I got undetectable down, there’s not really much immune response anymore. I think with these guys being less effective than your typical capillary, that would probably end up killing people pretty well. But that takes a long time, and that might not be desirable. I wonder if there’s anything I can do about that.

I think I got it nailed down. Once there’s not many more places for them to go, maybe there can be a trigger to let the body became aware of them. At that point, either the inflammation offs them, or they get treated and there’s just a whole mess inside. Either way, that means it’s just the breeding rate that matters. I kind of feel bad making them something that works by being killed off, but I don’t feel comfortable making them transmissible. I saw enough of those pandemic horror stories back in college.

[No date was present for the final entry, which was on an otherwise blank page after all other information in the notebook.]

Of course you fucking used them. Why did I think you wouldn’t actually use them? I’m the idiot here. Test project. I should’ve known better than to trust that. Thanks for fucking my career path. I quit.

Due to the implication that former members of Merkator Biolabs have acquired anomalous technology and are actively using it in the production of biohazardous anomalies, Merkator Biolabs is to be designated a GOI and investigation into its ongoing activities is to be designated an alpha-4 priority.
