A biosafety laboratory is a scientific institution that conducts experiments and research on pathogenic microorganisms.
Such institutions are devoted to the research of pathogenic factors, the development of therapeutic drugs, and the protection and guarantee for the safety of human life.
Biosafety laboratories are divided into four levels according to the degree of biological danger of the research objects. The first-level laboratory has the lowest requirements for biosafety isolation, and the fourth-level laboratory has the highest requirements.
Tier 1 laboratories, where research and treatment are conducted, are causative agents that pose little harm to healthy adults, such as chickenpox. Personnel working in Tier 1 labs only need to wear gloves and face protection, some test benches are open, and some labs are not even isolated from the public.
The second-level laboratory, which studies and deals with causative agents that cause only mild disease in humans, and often has preventive and therapeutic methods, such as measles. The secondary laboratory will be isolated from the public, and only experimental personnel will be allowed in and out.
The third-level laboratory, which conducts research and treatment, can cause serious or fatal diseases in humans, and can spread in the form of droplets. There may be prevention and treatment methods for such diseases, but we must always be vigilant. For example, rabies and AIDS, such as the SARS coronavirus that once ravaged the world and still makes people shudder to mention it, belong to the third level.
Staff working in research and processing in the tertiary laboratory, even if they are experienced, must receive special training for pathogenic factors in advance, and the laboratory must be completely sealed and under negative pressure to prevent indoor gas from leaking to the outside.
When conducting experiments, very strict protective measures must also be taken. Before entering the laboratory, staff must put on protective clothing in the buffer room. All experiments need to be carried out in biological safety cabinets.
The third-level laboratory already has such strict safety protection measures.
The third-level laboratory is already the pathogenic factor of AIDS and SARS.
So, what about the highest-level Tier 4 labs
The fourth-level laboratory, the highest protection laboratory, the laboratory of the highest level of biosafety in the world.
What it studies and deals with is a pathogenic factor that people know little about, is extremely deadly, spreads in the air with droplets as a carrier, there is no preventable method, and once infected, there is no cure.
Therefore, people also call the fourth-level laboratory "devil's laboratory".
The fourth-level laboratory needs to be completely isolated from other buildings in the vicinity, and it needs to install a special air-conditioning system with a filtration degree of 99.999%.
It needs to use a negative pressure system in the laboratory, and its pressure reaches negative 40 Pa, which is to ensure that the air in the laboratory does not flow outward.
All experimenters must be strictly trained and wear fully enclosed protective clothing before entering the experiment. There will be a long air pipe behind the protective clothing. The laboratory's independent oxygen supply system passes through this air pipe to the protective clothing. Internal air delivery.
Experimenters want to reach the core area of the laboratory, they need to go through 10 doors. These 10 doors are all interlocked. If one door is not closed, the other door will never be opened. This is done to avoid air circulation.
Experimenters coming out of the core area must first use chemical showers and ultraviolet rays in the disinfection area to repeatedly disinfect the surface of the protective clothing, and then enter the buffer zone to remove the outer protective clothing, masks and outer gloves.
Protective goggles should not be removed until the laboratory door is closed.
After that, you need to go through another buffer room and retreat to the preparation room. In the preparation room, they can remove all protective equipment on their bodies and take a bath immediately.
After completing this series of tedious work, the experimenter can leave the laboratory.
-What are the causative factors that make people so strict, cautious, meticulous and nervous, or, in other words, deadly viruses, which are even more dangerous than SARS, and which may cause global catastrophe if you are not careful
Vibrio cholerae has a mortality rate as high as 25% to 60%.
Bacillus anthracis has a mortality rate as high as 20% to 60%.
And, the mortality rate can be as high as 90%, Ebola virus.
Unlike cholera, which can reduce the mortality rate to 1% with prompt treatment, and anthrax, which is not transmitted directly from person to person, Ebola virus can be transmitted through human blood, saliva, excrement, and vomit , is the deadliest viral hemorrhagic fever and the most severe infectious disease virus in the world today.
How terrible is the Ebola virus, some people say that it can kill people twice.
Personally kill once, physically kill again.
The brain tissue of patients infected with Ebola virus will be severely damaged, which will make them insane and depersonalized. Some people will be as manic as rabies, and some people will strip naked and bleed all over. like zombies.
So some people call Ebola a zombie virus.
But its scariest part isn't here.
When the Ebola virus enters the human body, it will frantically attack the cells of the blood vessel wall, weakening the blood vessel wall or even breaking a hole, causing a large amount of internal bleeding.
At the same time, it will also attack the collagen protein, which is the connective tissue that fixes the internal organs of the human body. It will turn the collagen protein in the human body into a slurry, so the surface of all the internal organs of the human body begins to appear, even the skin.
Blood poured out of these holes.
The skin, muscles and bones are filled with a slurry of collagen protein, and there is no way to stick to it, so it hangs on the human bone as if it is about to fall off.
At this time, all the pores in the human body will seep blood outward, and the blood in the body can no longer coagulate, but it will become more and more viscous under the action of the virus, and it will adhere to the blood vessel wall to block the blood flow and cut off the blood. blood supply throughout the body.
The human brain will experience severe spasms due to lack of oxygen, the heart will seep blood everywhere, the liver will swell and rupture, then purulent and rot, the kidneys will be blocked by blood clots and necrotic tissue, and urine will flow back into the circulatory system. All the blood vessels and intestines are no longer held together, they die, are slowly broken down, and flow into the body cavity like water, floating in the body fluids.
At this stage, the Ebola virus has completed the living liquefaction of the human body.
Then, the blood continues to pour out of the holes in the body, people will vomit frantically, and vomit out the blood in the body that has become thick and black as pitch due to the virus, and the necrotic and blackened internal organs and tissues. .
At this time, the person is already dead in terms of personality, and only the remaining areas in the brain that can control the most basic physiological behavior support the final behavior of the person. Yes, at this time, the "human" can still move, but it is no longer a living person. It is like a zombie, without thoughts, feelings, or memories. There is only a body left wantonly played by the virus.
When the liquefied and decomposed organs and tissues in the human body are broken and excreted from the mouth and anus, when the person slowly melts into a pool of blood, the Ebola virus that killed it to death will pass through these things. Capture the next host.
"Severe convulsions before death cause the limbs to twitch and shake like crazy, and they throw blood and internal organs all over the place, which increases the rate of transmission and infection, as if the virus were alive and conscious. , I want to continue to use the host's body to parasitize, I want to kill more human beings, and I want to make myself stronger." Qin Ci said this, and raised his eyes to the people in front of him who were too horrified to speak.
"I originally thought that Xiao Kai's way of dying was just the usual supernatural form of death in the painting, and I didn't think about the 'normal' disease in the real world at all, but I didn't expect that this painting actually used a real existence The way of death... Of course, it still processed this way a little bit, shortening the time from infection to onset, usually the shortest incubation period after Ebola virus infection is 48 hours, and this painting is in order to comply with every The law of the dead at night has shortened the incubation period and the onset period to around 24 hours. Now, I can confirm that the three Xiao Kai and the others, as well as the 'blood case' that happened in every house in this residential area, are The culprit is the Ebola virus."
Qin Ci's voice fell behind, and after a long time, he finally heard Ke Xun speak first: "So... those human skins and those unknown objects wrapped in blood are... "
"It's the former owners of these houses," Mu Yiran took his words. "Those unknown objects are probably the fragments of organs and tissues in their bodies, and the only human bones that Ebola virus will not eat."
"So, so... So it's not that there are no people in this place, they're all still there, just... they're all dead like this..." Luo Meng was so frightened that his face turned pale and his body trembled.
At this moment, he suddenly discovered that there is a disease in the real world that is more terrifying than the power of ghosts and gods.
"But these dead people, why are they attacking us?" Shao Ling slowed down, "Is there any purpose for them to do this? Is it related to the search for signatures?"
"I think it may not be their own will that manipulated the dead, but... the will of the Ebola virus that resides in their blood." Qin Ci turned his face slightly, looking at the wall that was splattered by He Tang. The tainted blood, "At this point, they are still endowed with supernatural powers. We are the new predestination, they desperately want to parasitize us, so they will launch an encircling attack on us. attack."
"Is the Ebola virus really a living organism?" Zhu Haowen asked.
"It stands to reason that a virus is not a living thing and cannot be considered a living body, but," Qin Ci re-looked at the people in front of him, "but the Ebola virus is very special. Biologists have different opinions on whether it is a living thing or not. the opinion of.
"When Ebola viruses are outside the cellular structure, they are quiescent, inanimate, nothing happens, and can even crystallize.
"But as soon as they are absorbed into the cellular structure, they immediately become alive, using the host's cells as raw material for replicating themselves, and then killing them.
"So some people think that this characteristic makes the Ebola virus in a gray area between life and non-life, saying that its most terrifying and weird thing is 'neither life nor death, stepping on the yin and yang'. Ebola's The carrier of genetic information is considered to be the oldest and most primitive life-encoding mechanism, and its history can even be traced back to the early days of Earth's history.
"So, whether it has 'life' and consciousness at all, I can't be sure."
"Since we already know the truth of the 'blood case' that happened in this place, then we are not far from finding the signature," Ke Xun said with encouragement and optimism, "Brother Qin, we still have time, not the last minute. , none of us should give up!"
Qin Ci smiled, nodded lightly, looked at where Tian Yang was, and sighed: "Unfortunately, Tian Yang didn't have time to tell the clue about the age."
"No, he already told me." Ke Xun's voice was low.
At the last moment before his death, although Tian Yang could no longer speak, even though his personality had been killed by the Ebola virus at that time, he still tried his best to put this crucial clue into the He believed that Ke Xun must be able to understand it, and passed it on.

Here, I offer 82-year-old Coke to the big guys in the comment area who guessed Ebola early on! By the way, I remember that it seems that this painting has only been published for three or five chapters. Before the first deceased person was posted, the big guy guessed Ebola. It was amazing! How did you guess it! !
What also terrified me was that, while writing this painting, the news of a new Ebola outbreak in the Congo was announced. This subtle coincidence gave me goosebumps. It also fits the plot too well, and the coincidence is so scary... Could it be... I'm just a pictorial pusher? emmm…
Finally, this drawing will scare the little fairies who don’t know much about Ebola: the description of the condition of Ebola in this chapter is basically true, (unless the dozens of materials I consulted use artistic exaggeration So when I think about it this way, I feel even more terrifying. When I first learned about this virus, I was so scared that my whole body became cold and my scalp numb. Fear.
Finally, I hope this epidemic can be eliminated as soon as possible, and bless the people in the epidemic area!
