The '''Eurosky Low-Emission Infectious Disease''' (低辐射广域性感染症 or 广域性低辐射感染症), or ''ELID'' (“EILD”, “ED”), is the result of exposure of a living creature to the radiations of [[Collapse Fluid]].<ref>{{cite|cf1|part. 3}}</ref> Persons who went through complete infection without dying start acting similar to zombies, and are called “ELID Infected” or “ELIDs” (“ED Infected” or “ELIDer” in Chinese). Infected are hard to kill due to the layer of hard silicon formed over their skin. The [[Assault Artillery]] platform was originally designed to destroy ELIDs.<ref name=Bakery6 />

The symptoms for acute exposition to Collapse Fluid radiations (such as a Collapse Bomb) include coughing blood,<ref>{{cite|gfl|sg|3-5, [[Angelia]] coughs up blood after {{doll name|M4A1|AR|5|costume=costume1}} uses a [[Collapse Fluid]] bomb}}</ref> pain in the head and stomach,<ref name=Iso>{{cite|gfl|iso|Under the Wall II}}</ref> loss of vision<ref name=RC31 /> and/or a sensation akin to one's bones piercing through the skin,<ref>{{cite|gfl|12-3|[[the Commander]] describes the sensation they felt after the Collapse Bomb detonation}}</ref> convulsions,<ref name=Iso /> fatigue, scorch marks on the skin and periods of unconsciousness.<ref>{{cite|gfl|ct|3-5A Sum of All Wraths}}</ref> Most people die directly from radiations due to their average body resilience, but healthy people like soldiers can survive to reach the worst stages of irradiation.<ref name=CT31 /> Despite this, children can still turn into infected.<ref>{{cite|gfl|12-3|an infected girl attacks {{doll name|ST AR-15|AR|5|costume=costume2}} and [[Dandelion|M4A1?]]}}</ref> As silicification<ref>{{cite|gfl|ms|Dreams on the Island of Dia IV}}</ref><ref>{{cite|gfl|pr|E1-11}}</ref><ref>{{cite|gfl|ls|E24}}</ref><ref>{{cite|rc|[[Reverse Collapse Worldview#Silicification|Keyword]]}}</ref> (硅化, also translated “silication”<ref name=CT31 /><ref>{{cite|gfl|dr|Pollinosis II}}</ref> or, improperly, “siliconization”<ref>{{cite|gfl|sc|E3-1}}</ref>) occurs, their muscles and blood vessels will harden and their mind progressively withers to basic aggressive instincts.<ref name=CT31 /> Due to this stiffening the soon-to-be infected maybe unable to flex their fingers and turn their own weapon on themselves.<ref name=Iso />

Advanced ELID infection contracted by repeated exposure for short periods of time manifests physically as bluish-green skin, extremely fast aging made evident by geriatric wrinkles and crows' feet on the face, difficulty to breathe, muscular weakness and very unstable vital signs. Body amino acids decompose, connective tissues break down throughout the body, red blood cell count falls rapidly along with blood oxygen carrying capacity and the skeletal structure changes, undergoing calcification and increasing the density and hardness of bones to numbers up to 400 HB, far beyond conventional steel. Onset period increases as the body is repeatedly exposed to relics. Acute infection is fatal within 61 hours. Conversion to infected can take 24 to 48 hours, but necessitate the body to be healthy enough to survive DNA recombination.<ref name=Bakery9>{{cite|bg|Secret Document 9}}</ref> Under heavy radiation doses, transformation can take only minutes.

==ELID Infected==
[[File:RC BG elid.png|thumb]]
Standard ELID Infected are attracted to sound and moving objects not produced by other ELIDs.<ref>{{cite|gfl|ct|3-10 White Doll, {{doll name|RO635|SMG|5}} uses her megaphone to lure ELIDs}}</ref><ref name=RC31 /> Low-frequency acoustic emitters are used to lure ELIDs<ref name=RC31 /> and sonic bombs to repel them.<ref name=RC32>{{cite|rc|3-2}}</ref> The source of their killing impulse is unknown but they seem to attack everything but themselves indiscriminately and become more aggressive the longer they have been infected.<ref name=CT31>{{cite|gfl|ct|3-1 ELID-Infected}}</ref> However, in areas with particularly high radiation levels where there is no living creature to feed on, ELIDs can cannibalize each other.<ref name=RC31>{{cite|rc|3-1}}</ref>

ELID infection confers great resistance to the body.<ref name=RC31 /> Even in early stages, as much as seven handgun bullets can be necessary to put a human ELID down.<ref name=CT31 /> They seem to retain a certain degree of muscle memory, as demonstrated by infected soldiers actually firing their rifles haphazardly, though they are not capable of more complex actions like launching grenades.<ref>{{cite|gfl|ELID Infected Armed enemy description}}</ref> Soldiers severely irradiated undergo skin and internal organs mutations that make them both larger and more resilient than other infected, becoming [[Smasher]]s,<ref>{{cite|gfl|BOSS Zombie enemy description}}</ref> "Chimera" or "gigantified".<ref>{{cite|pnc|[[PNC_Story/Eager_Fist,_Dawning_Fray_Nodes|Eager Fist, Dawning Fray Nodes]]}}</ref> Some have been described as spewing acidic fluids.<ref name=Transcript />

The Nytos from [[Paradeus]] recognize ELID infected as “baptized” and refuse to harm them, even when attacked.<ref>{{cite|gfl|ct|3-10 White Doll}}</ref> [[Shrike]] cells also have the strange property of being able to absorb ELID biomass.<ref name=RC32 />

===Type D===

Infected staying in radiation zones for extended periods of time will undergo more drastic physical changes, with Type-D infected (D型感染者) being completely inhuman and monstrous in form, and requiring [[Assault Artillery]] platforms to take down.<ref name=Bakery6>{{cite|bg|chapter 6}}</ref><ref name=Transcript>{{cite|rc|[[Secret Documents#Transcript of Zone Definitions]]}}</ref> These poorly-studied creatures can become the pack leaders of lesser ELIDs.<ref name=Gray /><ref>{{cite|rc|Chapter 3, Act 3}}</ref> While they have been described as the most dangerous ELID creatures,<ref name=Transcript /> it is implied in other sources that even more dangerous types exist.<ref name=Gray>{{cite|gfl|[[Gray Zone Exploration]], “Corpse of a Gigantic Mutated ELID” event}}</ref>

==Immunity and cure==
There are two types of immunity to ELID, designated “semi-immunosome” and “pan-immunosome”<ref>{{cite|gfl|ms|Ariadne’s Clew III}}</ref> (or “fully immune individual” in [[Reverse Collapse: Code Name Bakery]]). Semi-immunosome humans can be in close contact with Collapse radiation or ELID infected with no adverse effects. Semi-immunosome immunity can be innate or acquired. Known semi-immunosomes include [[Machlian]] (innate) and [[the Commander]] (acquired).<ref>{{cite|gfl|ms|Atropos’ Shears I}}</ref> Known pan-immunosomes are [[Kawasaki Kazusa]]<ref>{{cite|rc|Worldview “Fully-immune individual”}}</ref> and the products of the [[Three Goddesses project]].<ref>{{cite|rc|2-3}}</ref> [[Isomer White]] and [[Nyto]]s are immunosomes of unspecified type.

The search for an effective, cheaply produced and easily distributed ELID cure sunk many pharmaceutical companies who tried to synthesize it. Some advocated that ELID cures were only tackling the symptoms of a wider environmental problem,<ref>{{cite|gfl|ms|Torricelli’s Trumpet II}}</ref> but a variety of cheap fraudulent cures or protective products were sold in the streets of Green Zones.<ref>{{cite|gfl|ms|Ship of Theseus I}}</ref> In 2064, Galatea Technology Corporation, backed by [[Paradeus]], attempted to bring the Idunn Formulation Type-III to market, supported by renowned surgeon Lady [[Gray]]<ref>{{cite|gfl|ms|Torricelli’s Trumpet I}}</ref> and ELID treatment specialist [[Minor Characters#Eugene Rugosa|Eugene Rugosa]].<ref>{{cite|gfl|ls|35-R3}}</ref>

By 2074, human infection was considered solved and infected fauna was the main danger posed by ELID<ref>[https://weibo.com/7367502517/JvRoQwCcX Weibo - E.L.I.D]</ref> (though ELID still plagued populations without access to treatment two decades later).<ref name=RC21 /> During the [[First Antarctic War]], Antarctic Union soldiers received genetic modifications and used radioactive decay barriers meshed into bulletproof vests that enabled them to operate in contaminated areas without special equipment for a short time.<ref>{{cite|rc|Chapter 2, Act 6}}</ref> [[URNC]] soldiers did not have these benefits.<ref>{{cite|rc|Chapter 4, The Rescue}}</ref>

==History==
ELID has been an ongoing problem during the exploration of [[relics]] sites, and spurred the development of the [[Weight Bearing]] protection system.<ref>{{cite|cf1|part. 2}}</ref> In early infection cases, before the 21st century, radiation sickness treatments were applied to no avail due to a lack of understanding of the mechanisms of ELID. This posed considerable problems as relics research ramped up during the Cold War, since infection vectors were unknown and no protection or treatment existed, leading to an estimated 150 000 ELID infections worldwide between the first documented case in 1976 and 1980, with about 10 000 infected. 50 000 new cases had appeared a year later, with a higher percentage of Infected and new mutation forms. High variance in infection conditions and combat data rendered global studies useless. Countries started to create special units dedicated to manage ELID cases, like the Chinese [[Special Circumstances Armed Police Force]], but the infection rate of these agents was high. The [[Relic Arms Limitation Treaty]] and détente between the [[Soviet Union]] and [[United States]] permitted Anti-ELID vaccine research to begin in 1983, gradually reducing the number of cases.<ref name=Bakery9 />

By 2023, genetic augmentations were available to boost resistance against ELID.<ref>{{cite|cf1|part. 4}}</ref> In 2048, during [[World War Three]], the [[United States]] established the Aurora Experimental Unit to develop ELID bioweapons based on cheetahs, leopards and bears injected with Collapse fluid. Aurora failed to find a way to control these creatures before they disappeared in 2050, but isolated the DNA sequences responsible for their mutations by comparing them with he DNA of the subjects from the [[Black Lily and White Rose project]].<ref>{{cite|rc|[[Secret Documents#Experimental Unit "Aurora" Mission Overview]]}}</ref> By 2064, severe Collapse Fluid irradiation could be treated as long as the patient had not turned yet, as exemplified by [[Angelia]] and [[the Commander]]'s survival.<ref name=CT31 /> Enough ELIDs existed in the Belgrade region in the 2060s to pose a significant threat to the city once the quarantine walls were breached.<ref>{{cite|gfl|iso}}</ref><ref group=Note>In [[Continuum Turbulence]] E3-1, {{doll name|AK-12|AR|5}} says that ELIDs have been rare since [[World War Three]]. This is disproved by later stories where ELIDs are frequent occurrences.</ref>

[[William]] cultivated massive quantities of Collapse-radiation filled [[Epiphyllum]] flowers and created dirty bombs to infect population centers, in order to identify a pan-immunosome he could use for his plans. After finding the semi-immonosome [[Machlian]] in [[Germany]], he extracted large quantities of her blood to create an effective ELID cure.<ref>{{cite|gfl|ms|Cretan Labyrinth II}}</ref>

With the progress in human treatment against ELID, the main danger posed by the disease shifted to the wildlife of the contaminated regions by the 2070s. The term "ELID Infected" was replaced by "ELID Silence Dread" or "living skeletons/hollows" (生骸) due to the changes occurring in contaminated animals. Despite their dangerous nature, some like the Obsidian Hare were captured and sold as pets, leading to casualties in owners.<ref>[https://weibo.com/7367502517/JvRoQwCcX Weibo - E.L.I.D]</ref> ELID still plagued refugees populations in the 2090s.<ref name=RC21>{{cite|rc|Chapter 2, Act 1}}</ref>

==Trivia==
*In [[Codename: Bakery Girl]], ELID is said to have been prevalent in northern Ukraine due to the Chernobyl incident and the Soviet “Koschei system”. The game also says that ELID vaccines were lost because of [[World War Three]] and the [[First Antarctic War]], which is now contradicted in canon.<ref name=Bakery6 />
*[[Mendo]] is fascinated by ELIDs and extensively studied them. On the contrary, [[Jefuty]] is terrified of them and disapproves of Mendo's interest.<ref name=RC31 /><ref>{{cite|rc|Chapter 4, Zombieland}}</ref> In Chapter 3, Act 1 and Chapter 4, Zombieland of [[Reverse Collapse: Code Name Bakery]], if Jefuty is more than 4 tiles away from Mendo, she'll start shivering.
