CA-SNT (Sanōta)

"I remember her. I can still hear her screams and all the cries of help she made, but what can I do? I had to put her down for everyone's sake. They always said death was bliss, but not when its from that goddamned pathogen!"

== CA-SNT (Sanōta) Biochemical Agent Overview ==
Sanōta (written as either Sanouta or Sanohta), officially referred to as CA-SNT in MID records and colloquially referred to as the "Saya pathogen", is an infectious and lethal biochemical agent first utilized by the Americans during the Eurasian War. It is noted for being an intensely contagious agent, with an r0 (reproduction factor) of 23 persons per every infected host. Current information on the agent is scarce, along with any possible remedies or antidotes. A typical occurrence with most biochemical projects by the United States during this time.
CA-SNT first originated as the product of a reinvigorated biochemical research program spearheaded by the US Army's Medical Research on Infectious Diseases Command stationed at Fort Detrick. Among many other agents used in the war, CA-SNT was meant to be a "mass-casualty agent" that would be dropped via bombers onto Chinese cities and would result in death in the most grotesque manners possible. The aims of the program were not just to cripple the Chinese manpower supply, but in the process, reduce morale exponentially.
There have been only two known instances of CA-SNT's usage in combat, that being the Bombing of Harbin and the Battle of Hainan, which resulted in severe casualties for all sides, both civilian and military. This resulted in CA-SNT being removed from US military stocks, though it is assumed that SNT-armed missiles remain in operation even amid these restrictions. It has also been seen in use by RFLN forces, resulting in the deaths of 37 people.
== Symptoms, Exposure, and Treatment ==
"I doubt she'll survive until next week. It's either suicide or her blood turning green (septicemia) that's gonna make her croak..hopefully...

Sanōta is, mentioned in the previous section, a lethal and infectious biochemical agent. With a maximum exposure dose of <2mg and an infection ratio of 23 persons per every infected "host". While its ferocious infectivity along with lethality instills fear and hopelessness amongst those infected and those whom have to bear to see their loved ones suffer, luckily, the agent cannot survive beyond 12 hours following ejection into the atmosphere, increasing the maximum exposure dose per every passing hour with a rate of +1mg per every passing hour.
Below is the a complete chart of each stage and short descriptions of their progression.
===== STAGE I: =====
Stage I is described to be the only stage where the Sanōta agent can be "cured", though unconfirmed cases have alleged that it may be treated later, around Stage II or Stage III. It appears a week following exposure to the Sanōta agent. Stage I causes the victim to become weak and feverish, their average temperature reaching 37.8C, along with other flu-like symptoms such as vomiting, sweating, inconsistent shaking, and increased production of mucus. Symptoms persist for the next week, eventually receding.
===== STAGE II: =====
Stage II appears between 1-3 weeks following the onset of Stage I. While similar to the latter, malaise (weakness) and fatigue are more stronger during this stage. Individuals also experience mental symptoms such as auditory and visual hallucinations, along with slight amnesic episodes. Like Stage I, the stage clears following at least a week.
===== STAGE III: =====
Stage III appears following three weeks after the onset of Stage II. By this time, inflammation of the skin causes it to turn reddish, followed by a fever reaching 39C. Gastrointestinal symptoms such as vomiting and diarrhea are intense and can overwhelm the infected individual, only worsening associated mental symptoms. It is also common for the afflicted individuals to experience ringing in the ears along with reddened eyes. There is no remission in this stage.
===== STAGE IV: =====
Stage IV appears following at least two weeks of Stage III infection. The skin begins to accumulate a gelatinous liquid around the arms, hands, back, and legs. Clustered in small quantities. these clusters cause intense pain to the infected individual, only worsened by over-accumulation of mucus. The infected individual's mental state is severely compromised, with the infected slowly losing the ability to conduct basic functions, rendering them bedridden for the remaining duration of the infection.
===== STAGE V: =====
Stage V appears following 72-120 hours of Stage IV. The infected individual starts to bleed, with the gelatinous pockets of liquid bursting, resulting in the formation of tentacle-like structures across the body. The voice box (larynx) malfunctions, reducing the individual's speech processes to cries and hisses. Skin starts to rot around the tentacle-like structures, spreading across the entire skin with the possibility of septicemia within a few hours. Bleeding begins to intensify, with the most commonly-affected orifices being the anal orifice and the mouth.
===== TERMINAL STAGE: =====
Following Stage V, the victim will attempt to kill themselves due to a severely compromised mental state and the intense pain brought about by the growth of gelatinous structures, which are now burrowing under the skin, not to mention the intense bleeding from the orifices. It is also common for orange-colored liquid to leak from the infected individual's mouth, which is believed to be the agent itself. 
Victims have been described by researchers to lie down on the floor and attempt to grab or hug an object, which is believed to be the manifestation of the disease's mental effects. Based on an infected researcher's testimony, the apparition is different in form depending on the person, but is usually manifested by an angel-like female character. 
Death sets in within a week or more following the terminal stage, the victim succumbing either to septicemia, suicide, or blood loss.
