 Item number SCP-2350 Object Class Keter Special Containment Procedures A recording of SCP-2350 is stored on a secure USB drive in the Site-42 digital armory. This drive should only be handled by Deaf personnel or personnel wearing industrial-grade earmuffs and earplugs. While Task Force's Lambda-12, Pest Control, and Upsilon-4, Sugarpill, have been jointly assigned to handle containment of SCP-2350. Upsilon-4 is working to develop an inoculation against SCP-2350's effects, while Lambda-12 investigates potential SCP-2350-1 events occurring in Vietnam. If Lambda-12 locates an area affected by SCP-2350-1, they will determine the radius of the effect and establish a containment perimeter around it. The Foundation will then liage with the Vietnamese government to establish affected areas its wildlife preserves. The Foundation is currently attempting to negotiate with the United States of America or the release of certain classified files within their archives. If necessary, political pressure may be placed on the USA to achieve this end. Description SCP-2350 is a weaponized memetic agent transmitted by sound that manifests as the idea of a swarm of mosquitoes. Human beings that hear SCP-2350 will perceive this swarm as attacking them, though Deaf humans are unaffected. For every 12 seconds that SCP-2350 is audible, the perceived size of the swarm will double. Humans affected by SCP-2350 will suffer from rashes and other inflammatory responses consistent with mosquito bites. Affected humans may also develop symptoms consistent with mosquito-borne diseases such as malaria. In several cases, patients develop a combination of symptoms not associated with any specific disease, but with mosquito-borne diseases in general. SCP-2350 was developed by the United States as a weapon for aerial denial and saw extensive use in the Korean and Vietnam wars. The sound was stored on magnetic tape inside a mortar or bombshell, which was then launched at a target area. Upon landing, the mortar would play SCP-2350 until its power supply died. As merely being near these areas will result in infection by the meme, thousands of Vietnamese civilians were killed or driven from their homes. SCP-2350-1 refers to a phenomenon affecting sporadic areas of the Vietnamese jungle wherein SCP-2350 is produced without an apparent source. It is suspected that SCP-2350-1 resulted from protracted use of SCP-2350. Evident areas are entirely devoid of fauna. The native wildlife appeared to avoid these areas by instinct, while non-native animals introduced to the area immediately flee. Discovery The Foundation first became aware of SCP-2350 on April 30, 2005, with Mobile Task Force Lambda-12, Pest Control, and County Anomaly in Vietnam while tracking an outbreak of SCP-2810. During the expedition, Lambda-12 arrived in an abandoned cell. During the expedition, Lambda-12 arrived in an abandoned settlement affected by SCP-2350-1, whereupon a discovered a mortar intends to transmit SCP-2350 and were infected by it. Lambda-12 were able to flee and report the incident. Recordings from the settlement, announces a foot into the mortar, and cross-referencing of external intelligence led to the official designation of SCP-2350. Discovery Log Log begins approximately 1.5 kilometers from the settlement of interest. Four members of Lambda-12 are pursuing a pregnant instance of SCP-2810-1 in the form of an endochinese tiger. L-1 is equipped with a flamethrower, L-2 with a net launcher, L-3 with a tranquilizer rifle, L-4 with a standard-issued light machine gun. As the team tracks the instance through the jungle, they observe several organisms watching them, though none of the organisms appear to be infected. Approximately 0.25 kilometers from the settlement, Lambda-12 spots the 2810-1 instance, rooming itself and moves in. L-3 takes aim at the tiger and fires. However, at the same moment, the tiger stretches itself out and avoids the dart, which strikes the tree. At the sound, the tiger flees. L-3 says, Motherfuck! Oi! Shhh! L-3 says, No point boss, damn thing was off like a light. L-3 says, Alright, let's track it down again. Good man, come on lads, let's bag us the tiger. L-2 takes point, examining the instance's tracks and leading the group deeper into the jungle as they pursue. As the jungle recedes and the first few houses in the settlement come into view, the group's audio recording equipment begins to pick up a buzzing sound. Later identified as SCP-2350. A town? I thought you said this place was all jungle. Wasn't any of my maps? That's for sure. Say, any of you boys hear that? Hear what? That buzzing sound? Yeah. Hmm. Wonder what that is? What do you know? I hear it too. Hmm. Sounds like mosquitoes. L-3 slaps his left arm. Yep, mosquitoes. Sounds like there's a lot of the fuckers too. Right, safety's on, weapons down. Don't want to scare the locals, eh? We ought to ask about the tiger. Looks like it ran through here. Even the 12 proceeds further into the settlement. As they do so, it becomes increasingly evident that the area has been abandoned. Those signs of life are present, save the grassy vegetation between the homes in the settlement. All homes are covered in copious quantities of mosquito netting made from natural materials. Hmm. Doesn't look like anyone's been here since NAMM. We're in NAMM, dumbass. I mean the Vietnam War, cooter. Focus, where is everyone? L-4 stops suddenly and looks down, at the speed of the pair of skeletons. One is child-sized and laid out so that it overlaps the arms of the other skeleton. Right here. Jesus. L-2 kneels down and examines the skeletons. Looks like a mama and her kid. She was running away from something and tripped, but their bones are untouched. An animal didn't do this. Hey, you know what? Where are all the animals? All I can hear is mosquitoes. So what did… no tracks either. Just a tiger. And that thing looks to have gotten the hell out of dodge. What are you thinking? I am thinking that the animals around here are staying out for a reason. Lad, take a look at that. L-1 points towards the center of the village, before dropping his arm to slap the other. The rest of Lambda-12 follows his gaze and spots a large crater in the center of the village. L-2 looks back at the skeletons. Maybe a bomb? Not much of a bomb, man. Place looks fine. Duhed maybe? Should we check it out? Christ. What is with all these mosquitoes suddenly? Tell me about it. Let's take a look. Tracks leading that direction anyways. The group moves towards the crater. Noticeably, each member is slapping or scratching their own limbs, despite no mosquitoes being present. As the group approaches the mortar, the buzzing sound becomes louder. As they near the crater, the vegetation thins and the ground becomes progressively more cracked. When the group reaches the rim of the crater, they look down at it. At the bottom of the crater is a large mortar shell, bearing US Army markings with an abnormal shape. The mortar is shaped cylindrically, though it sides taper towards the top, and there is a bevel at the bottom. There is an open hatch on the side of the mortar. That ain't ominous at all. Knock it off. I'll go down there and check it out. You three keep an eye out for anything… weird. L-1 slides down the crater and approaches the mortar. He examines the hatch and reaches into it, pulling out a magnetic tape. What the hell is this? Uh, boss, I, uh… look up. L-1 looks up. The sky is clear, and no abnormalities appear present. Bloody hell. RUN! L-1 scrambles up the crater. He is held by L-2, and the group proceeds to flee from the crater, dropping their weapons in the process. It is unclear what they are fleeing from, as the camera recordings do not show anything abnormal. However, all members of L-12 are repeatedly slapping themselves all over their bodies. Into that hut! L-12 bleeds towards a nearby home, ducking under the mosquito netting and forcing her way into the home. Alright. What the bloody hell was that? A billion fucking mosquitoes. Holy fuck. Jesus, the goddamn sky was black. You think it was that bomb? If anyone could create this cock up of a place, it would be the Yanks. Right. Focus. How do we get out of here? Look around. See what you can find. I reckon we could cover ourselves in the mosquito net and get out of here. Sharp thinking. Right. See if you can find some around here. L-3 moves towards the rear of the hut, and comes across a bed covered in mosquito netting. There are a pair of skeletons lying on the bed, covered in netting. L-4 comes up beside them. Christ, what do you think happened to these two? Stard, I bet. Come on, help me with this netting. Poor bastards. Why didn't they just use the nets? Just get the fuck out of here. Maybe they didn't want to leave their homes, you know? L-4 slaps his arm. He and L-3 look at each other. Oh fuck. Boss, we gotta go. They're getting in. L-1 and L-2 approach, slapping their arms. I can see that. Right lads. Into the nets. L-1 and L-2 drape themselves in mosquito nettings, while L-3 and L-4 do the same. Should we like, go back for our guns? Do you want to? No. There's your answer. On account of three, we rush out of the house and out the village. Keep running. Don't stop. Don't slow down or slap into buggers. Just keep running. Got it? Got it. Got it. Got it. Good men. Okay. One. Two. Three. On account of three, L-1 pushes the door open and breaks into a sprint, followed closely by the rest of Lambda-12. Although the camera recording from this point suffers from heavy motion blur, no mosquitoes are visible, and the sky is clear. Despite this, each member of the Task Force reacts as if being attacked by a large quantity of mosquitoes. This behavior persists as the Task Force exits the boundary of the village and for approximately half a kilometer into the jungle. Once the Task Force is two kilometers from the village, Lambda-12 calls for extraction. Log Ends History of SCP-2350 Historical records of the ASCI indicate that SCP-2350 is descended from a memetic weapon used by Spain in the Spanish-American War, based on an Aztec prayer to Molino Sequitel. American Security Containment Initiative The Aztec Goss of Snakes, Scorpions, and Insects The efficacy of the Spanish weapon was limited by the primitive state of European memetics. The carrier's sound had to be made by a handheld noise maker that not cause any physical effects, and affected both Spanish and Americans. As such, the weapon did not contribute in any meaningful way to the Spanish war effort, and research on the weapon was relinquished to the United States as part of the Treaty of Paris in 1898. Records collected by Soviet intelligence indicate that the United States attempted to refine the weapon for use in both World Wars by developing an inoculation against a meme for use by Allied forces. The necessary breakthroughs to develop an inoculation were not arrived at until 1947. As such, SCP-2350 did not see uses in either World War. Pentagram research records acquired by the Foundation indicate that the first inoculation for the weapon was developed in early 1950, enabling its first deployment to be a naval shelling at the Battle of Enchin, the occult branch of the Department of Defense. The weapon would see further use as a tool to deny enemy supply lines and hold major choke points during the Korean War. It is suspected that several cancers of the weapon were breached in the Battle of Unsan to cover the retreat of American forces. Recovered Chinese records of the battle make repeated reference to large swarms of mosquitoes and roughly materializing at crossing points along the Yalu River and attacking all Chinese forces that attended to pursue the Americans. The former of the weapon classified as SCP-2350 was developed by the Special Operations Division of the United States Chemical Corps and deployed en masse during the Vietnam War under the codename Agent Black. In addition to having an increased swarm growth rate, the weapon was able to induce physical injuries in its victims. At some point prior to 1961, SCP-2350-1 began to manifest in Vietnam. The American inoculation was ineffective against this form of SCP-2350, enabling it to attack both communist and anti-communist forces indiscriminately. The United States attempted to curtail the spread of SCP-2350-1 through the Herbicidal Warfare Campaign, Operation Ranch Hand. Although this attempt was partially successful, it had the added effect of defoliating huge portions of otherwise unaffected jungle and displacing thousands more Vietnamese civilians. As of 2005, the United States had not acknowledged the existence of SCP-2350 and has repeatedly rebuffed attempts by the Foundation to gain access to its historical and novice archives through its traditional channels.
