Typhoid fever is transmitted by fecal-oral transmission.

In short, it is the infection caused by unclean contact with food and drink after excretion by livestock or human carriers.

The latent outbreak and the length of the epidemic during the disease period are related to the nature of the infection, with most food-based outbreaks occurring within 48 hours, while water-based outbreaks can be incubated for up to 30 days.

After Tong Han's description, it can be determined that Tang Yi's infection route is the former, which leads to the invasion of germs after drinking raw milk.

Isn't raw milk a source of water?

Water source refers to the diffusion of excrement in the water source, and after the amount of bacteria is diluted, the number of bacteria infected by the human body is naturally not high, and the number of bacteria in the body multiplies during the incubation period, and the disease will break out when it reaches a certain number.

And Tang Yi directly drank raw milk containing bacteria, which is equivalent to directly allowing germs to enter the human body.

As for how others don't have problems......

In fact.

This situation is really hard to say, the time of the outbreak of the disease varies from person to person, maybe after Tang Yi and Tong Han left, some people among the herdsmen were infected, but for now, no one will pay attention to those things.

It sounds very cold-blooded, but as far as Tong Han's experience is concerned, the local conditions are like this, if it weren't for Zhang Zhongjian to contact China Railway First Aid, otherwise it is not certain whether the two of them can get treatment, in the local area, human life is really worthless.

In addition, Tong Han's infection is of a affected nature.

Tang Yi vomited and diarrhea, and the local sanitation environment was poor, which inevitably led to infection when contacted.

Therefore, Tong Han's disease is milder and the number of bacteria is less.

After typhoid bacteria enter the body, they directly destroy the function of the digestive system, and the body's own antigens will also start to fight back against the bacteria, and the interaction between the two is like treating the stomach and intestines as a battlefield.

Who is affected? It can only be the digestive system, which is the battlefield, that has been beaten to the ground, and as a result, perforations and bleeding have occurred.

If Tang Yi could take antibacterial treatment as soon as he felt unwell, the current situation would definitely not occur, the problem is that the time has dragged on for too long, the number of germs has not been suppressed and skyrocketed, and the digestive tract has been frantically invaded and eaten.

During surgery......

Perforated intestines were marked everywhere, and the people in front of the stage looked more and more solemn.

The more markers, the more time they need to dispose of, and the greater the challenges they face.

The location of the contrast is only part of the result, and more need to be checked after laparotomy to confirm the diagnosis, and now-

"The number of piercings has exceeded our expectations......"

"There is blood in the ascites component, Professor Scott, could it be ......?"

Before Silan's words were finished, Jack said in a deep voice: "There should be a more serious perforation, more than the normal amount of bleeding from the perforation, I will continue to mark, you find the bleeding location...... Philip, ready for debridement, with me repairing the sutures. ”

Compared to Slan, Jack has always been organized.

It was a lot worse than they thought, but as a team leader, he had to get his rhythm right.

Side.

Zhou Zhou clenched his fists, and the bleeding point he had found by the system, the jejunum located in the anterior part of the small intestine. But he didn't dare to open his mouth at this time, Director Wang was on the side, even if he used English, it was impossible to hide.

But if Zhou Zhou didn't lie and said that he had something to do, he could have entered with Director Wang now, but now he ......

A lie always needs a myriad of ways to make up for it.

Hate.

Before you know it, the operation has been going on for five minutes.

It is still early to complete the best time of 30 minutes, but as far as the situation found now is concerned, 30 minutes is ironclad, the abdominal examination is only the first step, and the later disinfection and suturing are the troubles, which tests the technical literacy of a doctor the most.

Director Wang watched and listened attentively, although he had medical knowledge that ordinary people could not compare, but the dialectical thinking of Chinese and Western medicine was completely different, and he could not accurately know whether the current surgical process was good or bad.

It can only be supplemented by the brain, and there may be bleeding spots......

That should be bad.

The old man was sweating, watching quietly, and there was a feeling of regret lingering in his heart......

If you don't come in, you shouldn't have to worry so much, right?

Why bother before?

If you leave now, I'm afraid you'll disturb them again.

Director Wang couldn't sit still.

Duration of the operation, fifteen minutes.

"Debridement, ready for sutures. Jack started his hand, the instrument nurse immediately handed the equipment to his hand, Philip is the second assistant, cleaning and flushing at the same time, the small abdominal opening, the three of them are working separately.

Before preparing to stitch up, Jack paused and looked at Slan: "The bleeding point hasn't been found yet?"

Encountering questioning, Silan was obviously a little anxious: "No, no, I'll ...... as soon as possible"

"It's been ten minutes, have you performed it in the order of abdominal examination?"

"I, I...... I didn't, I thought the bleeding point should be in the chyme accumulation channel, so I focused on checking ......"

However.

Before Slan could finish speaking, Jack was furious and scolded: "Fake, damn it, what do you think, what do you think, are you joking with me?

"You can't do the simplest investigation, what the hell are you doing!"

With an angry shout, the atmosphere in the operating room instantly fell to freezing, and the already serious air seemed to be completely frozen......

But even though Jack was angry, his hands didn't stop.

Silan swallowed a mouthful of saliva and said with trepidation: "Give me another five minutes, it's almost there." ”

The nurse saw the cold sweat on his forehead and hurriedly wiped it for him.

And Zhou Sheng, who was in front of the operating table, had begun to hide himself, but he had to continue to remain silent.

……

Maybe because of Jack's anger, everyone was already under pressure, and now they can't control the rhythm.

Jack was suturing, and Philip's pinching forceps stabilizing the intestinal tissue shook slightly, which directly led to the crochet needle ectopic puncture in Jack's hand.

"Settle down, be steady, okay?"

Compared with Fang Cai's scolding, Jack is obviously much more restrained.

Because he also seems to realize that the combination in front of him does not seem to adapt well to his rhythm, and the more pressure there is, it will only lead to mistakes and omissions, and he does not dare to destroy the opponent's self-confidence again, which will directly lead to the loss of the whole game.

Philip apologized nervously: "I'm sorry, I'll take notice." ”

But what about Slan's side?

Time was getting tighter, but he couldn't find the bleeding point.

The position of the jejunum is very special, located at the front end of the small intestine, which is the first passage for chyme to enter the small intestine, butted above the abdominal cavity, and because of the particularity of the tissue, many blood vessels are attached to the surface of the jejunum, and it is reddish.

The bleeding point caused by the perforation is bound to be small, and the blood stain in the ascites is also a long-term accumulation process, so it is easy to ignore.

Even if Jack didn't ask, just looking at Slan's increasingly panicked appearance, he knew that there was no progress.

At this moment.

This is the case.

Jack really has an autistic impulse, obviously he usually plays very steadily, why does he have a slack at a critical moment? He has an impulse to come to the stage on Monday.

But he didn't dare to raise his eyes to look at Zhou, because he was still in the stage of struggling in his heart, and he was afraid of an impulse, so he spoke out.

Ancient times.

The ancients divided the rise of the profession into seven layers -

Slaves, apprentices, laborers, craftsmen, teachers, families, saints.

The first is the person who is involuntary or supervised.

The second is apprentices, who are not capable enough and are willing to learn.

The third person is a person who works neatly and according to the rules.

Needless to say, the craftsmen are highly skilled.

Master, master, master, master, mastered the rules and was able to teach the arts.

The family is a great success, the saint is naturally a sage, rare throughout the ages, taking the strange and obscene skills as an example, Lu Ban is holy, in terms of traditional Chinese medicine, Hua Tuo, Bian Que, Sun Simao can also be holy.

Jack belongs to the division, not to the family, but his abilities are definitely in the upper class.

Silan should be a 'worker', but in terms of the quality he presents now, he has the mentality of not working as well, and he can't do things according to the rules, so he can only be reduced to a disciple and lack of ability.

The status is fluctuating, and many factors can cause the level to fall.

As it stands, it's pretty bad.

Can you endure Monday?

No more!

He stepped forward and attracted everyone's attention, but he had to keep his composure, and he couldn't go on stage without Jack's approval—

"Jejunum!" said Monday in a whisper.

Everyone was slightly stunned, and even Jack didn't react for a while......

"Bleeding spots, look at the jejunum!"

The words fell.

Slan was stunned, but Jack was the first to come to his senses, handed the crochet to the nurse, and picked up the pinching forceps and clamped the jejunum segment, which was thick and folded, and had countless veins attached to it and were reddish.

But look closely......

Philip exclaimed: "There, the piercing oozes blood!"

Hiss!!

Everyone gasped, the authorities were fascinated by the bystanders, and they were suddenly awakened in the obstacle, precisely because they didn't know how the other party did it, and the inexplicable shock made the pores open and close all over the body.

Jack knew that there could be no delay, and he looked up and looked at Zhou for the second time since entering the operating room—

"Slan goes down to ......"

"Zhou, up!"
