Meningitis, whether caused by bacteria or viruses, has a common feature of being confined to the meninges of the brain. There is plenty of room for growth and expansion, with plenty of nutrients and a relatively easy "territory" to develop.

Mobs tend to consume the least amount of resources in order to get the most expansion. This "efficient" quality works equally well for humans and microbes.

But if Hunn's brain damage is not confined to the meninges, but penetrates deep into other areas and even the white matter of the brain. Then, what Sun Lien and they need to deal with is by no means an ordinary "meningitis caused by unknown pathogens". They can even directly rule out the possibility of common bacteria and viruses causing disease.

"There should be another CSF test. Hu Chunbo quickly made a decision, and turned to Hu Jia and asked, "They have centrifuges here, right?"

"Yes. Hu Jia nodded, "There is a testing laboratory with quite complete equipment here, and the laboratory doctors are still on the job - they are not ill." ”

Hu Chunbo and Sun Lien glanced at each other, then nodded. The group of otaku in the laboratory department were not infected, which made the two of them firm up their guesses.

"However, the intracranial pressure in the group of people who are now sick is too high. Cerebrospinal fluid (CSF) biopsy is risky. However, Hu Chunbo and Sun Lien's request for a cerebrospinal fluid puncture examination of the patient was denied by Liu Tangchun. "It's already dying fast, and if you wear cerebrospinal fluid again, are you worried that the chance of their brain herniation is not big enough?"

"But this test is really important, and if you want to kill them, a cerebrospinal fluid test is essential. Hu Chunbo was also anxious, and he shouted at Liu Tangchun, "If you don't do an inspection, everyone will have to die." After a test to confirm the diagnosis, at least a few will survive!"

"Do you already have a direction?" Hearing this, Liu Tangchun couldn't help but feel a little interested, "If you want to do a cerebrospinal fluid examination, do you think you must be able to see the pathogen in the cerebrospinal fluid?"

"It's hard to say ordinary, but a neck puncture should be fine. In fact, it is better to have a white matter biopsy, but the risk is too great for you to agree. Hu Chunbo replied, "Captain Liu, give me permission, this is saving lives!"

"Nonsense, it's also a white matter biopsy, why don't you split the human head and take a look?" Liu Tangchun glared at Hu Chunbo, but before staring, he first winked at Sun Lien. "We're here on a humanitarian mission, and we don't have to find out what disease they have—that's enough, do you understand what I mean?"

"Captain Liu, we are doctors. They are patients. Hu Chunbo's face turned red in a hurry, and he looked at Liu Tangchun with an incredible expression, "No matter how big their sin is, they just didn't let us enter the camp." Now that we have an idea, a direction, and even a certain diagnosis, how can we do nothing, and it means here?!"

Liu Tangchun has a very high reputation in the medical team, and because he usually handles things fairly and has a high level, he is basically the master of the same thing. In order to save a few Americans with a bad attitude, Hu Chunbo dared to work against Liu Tangchun like this, and even Hu Jia felt that Hu Chunbo's attitude was a little inappropriate.

After being silent for a few seconds, seeing Hu Chunbo's face getting redder and redder, Liu Tangchun suddenly laughed and said to Sun Lien, "Look, I have a good eye, right?"

Sun Lien nodded with a smile, there are fewer and fewer people who dare to talk back to Director Liu these years. Especially for a few terminally ill patients, the doctors who dare to argue with Liu Tangchun are even more of a few. Doctors need to obey the orders of the senior doctor, but they also need to resist the unreasonable orders of the senior doctor. When to obey and when to rebel is actually a very difficult question.

At least Hu Chunbo did a good job this time.

"Giving a paracentesis to a patient is too risky, and I still can't agree to it. Liu Tangchun smiled again, and then said to Hu Chunbo, who was confused, "However, I have a solution." ”

"Two hours ago, a patient died after treatment did not work. Liu Tangchun said to Hu Chunbo, "I have already talked to Dr. Iweala, and she agreed that we should dissect the patient to find the cause. Liu Tangchun paused and said with a smile, "I'll give you a permission now to split that poor man's head, find the pathogen, and then save the others." ”

Hu Chunbo was silent for a moment and nodded, "I'll check...... But the others ...... It may not be saved. ”

Hu Chunbo went for an autopsy. On the other hand, Sun Lien went to find Ms. Iweala again. This time, he had only one question, "Did you swim when you had a meeting before?"

"Swimming?" Ms. Iweala obviously didn't expect Sun Lien to ask this question, she was stunned for a moment before nodding, "Africa is too hot, and the boys want to cool off after drinking beer, so they often go to the small pond east of the camp to take a dip. ”

"Among the sick people in this batch, they have all gone swimming, right?" Sun Lien pressed step by step and continued to ask, "Many people have gone swimming, it doesn't matter. They've all been swimmers, right?"

Ms. Iweala's expression went from bewilderment to thoughtfulness to shock. Her eyes widened, "What do you mean ......"

"We are highly skeptical, but there is currently a lack of conclusive evidence. Sun Lien nodded and walked out of the room, "How far is the pond, can you find someone to take me?"

"To the east, you can see it directly after leaving the camp. Ms. Iweala was still so shocked that she even forgot to find someone to take Sun Lien out to have a look, "But...... Twenty-eight people became ill...... It can't be ......"

Sometimes science is the same as reasoning. When you rule out all possibilities, the last remaining option, no matter how incredible it may be, is the ultimate truth. Sun Lien walked to the edge of the pond, looked at the pool of water that was still clean and shook his head, who would have guessed that it was this pool of water that took the lives of more than a dozen people in a few days?

Taking a sample from the pool, Sun Lien returned to the camp. And the sample was given to the examiner who was looking at the microscope. He said to the American laboratory doctor, "You can take a closer look at this sample." ”

The American examiner hesitantly took the sample and asked, "So what are we looking for?" he explained, "We have to process the sample in different ways for different purposes." ”

"Look for any free-living amoebic protozoa in here. Sun Lien replied, "In the human tissue samples that will be sent later, what you need to look for is the same thing." ”
