Nan Zhiqiao and his entourage followed behind Zhang Wen and watched Zhang Wen's work.

Zhang Wen took the male passenger to the studio where the temperature was monitored, where there was a work desk with several forms to fill out.

The male passenger was very cooperative, picked up the pen on the side, and filled in one by one according to his previous experience.

After filling out the form, the male passenger coughed again.

Zhang Wen helped the male traveler and prepared to go to a nearby room to take samples.

Ye Zhenzhen stared at the male passenger who was coughing up blood, I don't know if it was because of the cough or some other reason, his face was flushed, his breathing was short, his lips were obviously blue, and his eyes were bloodshot.

Zhen Zhen remembered the early symptoms of the illness of an Ebola infected person she had seen in Sierra Leone, Africa, and her eyes were bloodshot.

Driven by professional habits, Ye Zhenzhen was about to step forward to ask the male passenger if he had been to Africa, when suddenly, the male passenger's legs went weak and he fell to the ground.

Zhang Wen was holding the arm of the male passenger, but as soon as the male passenger fell, Zhang Wen also stumbled and almost fell to the ground together.

"Sir, sir......"

Zhang Wen shouted, but the male passenger was unconscious and fell to the ground without any response.

Nan Zhiqiao and Ye Zhenzhen stepped forward, Nan Zhiqiao stretched out his hand to measure his pulse, and the pulse was fine.

The unconscious man's eyelids were opened, and his eyes were bloodshot.

Lifting his sleeves and lifting his clothes, the man's body was covered with blood spots, and his skin was purple, and in some places it had turned black.

You Kexin followed beside him, and when he saw the situation on the man's body, he took a step back in fright, leaned against Liang Chen's side, and muttered in a low voice: "He can't be dead, why is his body black and purple?"

High fever, coughing up blood, death, black-purple skin......

All the symptoms were linked, and Vera's mind quickly flashed through all possible illnesses, and finally locked onto one word, "Black Death".

Ye Zhenzhen just speculated, did not speak.

Zhang Wen was anxious and shouted to the staff who surrounded her: "Send him to the infirmary at the airport quickly." ”

Nan Zhiqiao intervened to stop him, "Send it directly to JS Hospital." ”

Zhang Wen thought about it for a while, and yes, the male passenger was in a coma, and the airport infirmary estimated that it could not handle it, so it was better to send it directly to a big hospital.

Zhang Wen was about to help lift the unconscious male traveler to the ground, but was stopped by Nan Zhiqiao.

Nan Zhiqiao instructed: "Zhang Wen, you continue to stay at your post, and Teacher Ye and I will send him to the hospital." ”

Nan Zhiqiao spoke, and Zhang Wen did not refute.

Nan Zhiqiao and Liang Chen helped up the fainted male passenger, the airport staff had already pushed the emergency bed, and the ambulance had also arrived outside the airport.

Pushing the emergency bed towards the ambulance, Nan Zhiqiao instructed Zhen Zhen who was following him: "Call JS Hospital first, there are infectious disease patients to be sent here, prepare the infectious disease isolation ward." ”

Zhen Zhen knew what to expect, and hurriedly dialed the number.

A group of hurried figures in the airport entry and exit passages began to regain calm as the fainted male passenger was sent away.

Not far away, a brown-haired mixed-race beautiful boy stood quietly in the crowd, looking at the back of Zhen Zhen and his group leaving, a slight disappointment flashed in his heterochromatic eyes, "Standing in such an obvious position, you still haven't seen me, is the patient more attractive than me?"

——

At JS Hospital, the male traveler was placed in an infectious disease isolation ward.

Nan Zhiqiao discussed the male passenger's condition with the attending doctor.

The attending doctor analyzed: "The patient had a high fever, coughed up pink bloody sputum, had a thin pulse, and was breathing urgently. Facial flushing, conjunctival hyperemia. Dyspnea and lack of oxygen lead to cyanosis of the skin of the lips, face, and limbs. Auscultation of the chest with crackles. X-ray, widening of mediastinal opacity. I suspect some kind of infectious disease that is causing the lung infection. ”

Nan Zhiqiao: "There are many infectious disease pathogens that cause lung infections, such as pulmonary anthrax and SARS caused by coronavirus, avian influenza and lobar pneumonia caused by pneumococcus, miliary tuberculosis caused by Mycobacterium tuberculosis, pulmonary hemorrhagic leptospira, pulmonary tularemia...... The causative agent must be identified for symptomatic treatment. ”

The attending doctor looked embarrassed, "For the detection of pathogens of infectious diseases, the hospital does not have a disease control system specialty, so I have to ask Director Nan for help." ”

Nan Zhiqiao: "This is also the responsibility of the disease control system, and the results will be fed back within three hours." ”

Zhen Zhen collected a nasopharyngeal swab and blood sample from the male traveler and brought it back to the CDC laboratory.

At present, the fastest way to detect pathogens is PCR nucleic acid testing, which took an hour on the way from JS Hospital to the CDC laboratory after the sample was collected, and two hours from the time the sample was processed in the laboratory to the test result.

The test result was as expected by Vera, positive for Yersinia pestis.

Yersinia pestis infection in humans can cause acute toxemia, bleeding tendencies, and damage to the lymphatic and vascular systems. According to the different clinical symptoms, it is divided into bubonic plague, pneumonic plague, and septicaemic plague.

Plague has a very high case fatality rate and is a naturally occurring disease that is first endemic to rodents and other rodents, and is transmitted among humans through fleas.

More than 2,000 years ago, plague epidemics were recorded. The plague pandemic has been recorded three times in history, the most notorious of which was the second, which occurred in the 14th century in the "Black Death" and affected all of Europe, Asia and northern Africa, killing nearly 30 million people.

The plague is a virulent infectious disease, highly contagious, and thinking of this, Zhen Zhen secretly screamed in her heart that it was not good.

The airport is like a big net that connects the whole world, where did this plague patient come from, where did he get the plague bacillus, and who did he come into contact with on the way?

These must be investigated clearly.

Nan Zhiqiao notified JS Hospital of the test results and contacted Zhang Wen to prepare for disease control personnel to investigate the people who had been in contact with the male traveler with plague, and they may have been infected by Yersinia pestis.

After investigation, the male passenger infected with the plague was on a flight from Lhasa to Beijing, and there were 118 people on board.

All passengers on the same flight were contacted and asked to go to a nearby hospital for a nine-day quarantine observation.

The incubation period of plague is relatively short, generally one to six days, mostly two to three days, and individual cases can reach eight to nine days, and the isolation observation period is set at nine days according to the length of the incubation period.

In addition to contacts on board the aircraft, it is also necessary to find out where the plague bacillus bacillus in the male passengers with plague came from.

To find out this, you need to know where he has been and what environment he has been exposed to.

——

Nan Zhiqiao, Zhen Zhen, and two staff members from the district disease control came to the airport.

Zhang Wen brought the form filled out by the male passenger before he fell unconscious, which contained his information.

Nan Zhiqiao took a closer look and found that the form was very general and vague, only stating that his profession was a photographer, and the purpose of going to Tibet was to take landscape photos.

Nan Zhiqiao looked at this information and sighed: "It seems that if you want to check your previous whereabouts, you still have to ask him in person." ”

Just as he was about to go to JS Hospital, Nan Zhiqiao suddenly received a phone call.

The call was from the attending doctor of the male plague traveler, "The plague male passenger has died!"
