P4 suits aren't very expensive, at least not more than 8,000 sets of P4 suits that the Centers for Disease Control, which is supposed to have deep pockets.

But protective clothing has an expiration date. From the time it is opened to the time it is discontinued, the shelf life of a set of protective clothing is about one year. If it weren't for the fact that Ningyuan Medical College had its own P4 laboratory, the Ningyuan CDC would probably never have thought about buying this level of positive pressure protective clothing by itself—this thing has to be put on and taken off, so why buy it well?

Therefore, when it learned of the outbreak of three cases of pneumonic plague, the CDC's first response was to activate the three sets of protective clothing in the inventory and call the P4 laboratory of Ningyuan Medical College at the same time - did you make a biological leak?

Yersinia pestis is a pathogen studied in the P3 laboratory, and the P4 safety standard is not necessarily required for its research. However, the P4 laboratory can carry out research on Yersinia pestis. Ningyuan is not a natural plague area, and it is the first time that the CDC has received a report of a plague case since its establishment, and they subconsciously suspect the P4 laboratory in their jurisdiction.

CDC staff were cold before they called. If the plague could leak out, who knows what else they were leaking. What if there was an outbreak of diseases like Ebola in a big city like Ningyuan, with a population of nearly 10 million...... It was a nightmare.

Fortunately, nightmares exist only in their imaginations. The P4 lab at Ningyuan Medical College said it did not have Yersinia pestis in their lab. This excludes the possibility of a leak in the first place. After the call, the CDC staff breathed a sigh of relief, but yes, with the P4 security level of the laboratory setting, it is impossible to even deliberately leak pathogens from the laboratory. There are seven airtight doors for this level of security laboratory light interlocking, and as long as one door is open, the other six airtight doors are absolutely impossible to open. Coupled with the highest level of surveillance and multiple thorough chemical rinses, it is better to suspect that a plague-stricken Himalayan marmot has traveled thousands of miles from Xihai Province to Ningyuan than to suspect that Yersinia pestis has leaked from the P4 laboratory. It's a little more likely.

At present, the Municipal Center for Disease Control and Prevention only has three sets of P4 level protective clothing, but there are four more sets in the four hospitals, and the college also guarantees full support, so in order to prevent the spread of the epidemic and protect the health of medical staff, it has become the safest choice for all to use P4 protective clothing to enter the four hospitals. After the report of Class A infectious diseases, there is still a lot of work that needs to be done by the Municipal Center for Disease Control and Prevention. For example, allocate resources, such as docking with the provincial CDC, and comprehensively consider whether it is necessary to seek help from the National Center for Disease Control and Prevention and the National Health Commission - it is a requirement to report within two hours after the discovery of a Class A infectious disease, and whether the National Health Commission will send an expert group to provide support and guidance depends on both the epidemic situation and public opinion. At the same time, local needs are also an important consideration. Sun Lien and others are still wearing standard protective clothing, the staff of the hospital office are urgently erecting positive pressure breathing tubes, and the mobile high-efficiency air filter transferred from the college is being installed. At the same time, a reception and treatment center was established for the collection and disposal of excreta from plague patients and medical waste.

The trouble with plague lies in the variety of routes of infection, and pneumonic plague patients are particularly thorough. In addition to the aerosols produced by their breathing, plague can be transmitted in the feces, urine, vomit, sputum, and blood of patients. In order to stop the spread, hospitals need to use a large number of disinfectants to disinfect and inactivate these medical and domestic wastes of patients. For solid feces, it is even necessary to use 20% bleach powder emulsion to add it, mix it well, and disinfect it for two hours.

If there's an Englishman here, it's a great job for him/her.

Before entering the clean room, all Sun Lien could do was empty thoughts in his mind to distract himself.

He was also afraid.

The bubonic plague is the Black Death, a terrible disease that has ravaged the world for thousands of years and caused the death of countless city residents, and at this moment Sun Lien has some preliminary ideas.

The incubation time from the infection of the pneumonic plague to the onset of the disease is simply unbelievable. The fastest recorded onset of pneumonic plague is 30 minutes – only 30 minutes from contact with a sick person to onset. After the onset of the disease, the patient's condition begins to deteriorate rapidly and he dies within about three days. In some ways, pneumonic plague can even compete with Ebola. It's just that because the causative agent of plague is bacteria, and many antibiotics work well against plague, it is not as scary as a viral infectious disease.

"Alright, let's assemble. Sun Lien was thinking nonsense, and Huang Wenhui, the director of the Department of Respiratory Medicine here, had already issued an order to the surrounding medical staff, "Prophylactic oral ciprofloxacin capsules, take them every twelve hours." ”

In addition to protective equipment, health care workers also need oral antibiotics for prophylaxis. Among the four prophylactic drugs recommended in the domestic diagnosis and treatment guidelines, tetracycline and compound sulfamethoxazole tablets are used in large doses, while doxycycline has obvious liver toxicity, so Director Huang Wenhui chose to let everyone take ciprofloxacin orally for preventive treatment - anyway, it is easy for the pharmacy in the hospital to provide drugs, since they are all "labor protection supplies", it is natural to choose the one that is less harmful to medical staff.

"I'll go in with you. Seeing that Sun Lien and the others ate the capsules, Director Huang himself swallowed two capsules and put on the mask again, "The laying of the clean room is still being done, time waits for no one, I will discuss it with the hospital, at least let me go in to see the patient's situation first-let the imaging department push a bed film over, they will definitely not be able to go to the CT room in this situation, and it is better to have an X-ray chest X-ray than nothing." ”

Sun Lien nodded, and then said, "I'll go in with you." ”

This time, Sun Lien really didn't swell from above, but made a decision after comprehensive consideration. In the entire treatment group, he is the most suitable person to enter the clean room- First of all, under the first diagnosis responsibility system, there must be a doctor in the treatment group to take over these three patients; secondly, Sun Lien has been in the room with patients who need to be isolated, and has completed many rescues, compared with several other doctors in the group, Sun Lien's ability to deal with emergencies is obviously better and more comprehensive; third, with the assistance of the director of the respiratory medicine department, Sun Lien's identity is actually more suitable for others; and finally, he has a status bar to use.

With the status bar, he is able to monitor changes in the patient's condition as quickly as possible, and can actually apply these changes to the actual treatment. For a person with pneumonic plague, even a little extra help can result in two completely different extremes – from death to life.

The most important thing is that Sun Lien has learned to be obedient. He knew more than any other emergency physician in the room the horrors of medical occupational exposure and nosocomial infections. He himself was quarantined for seven days, his own director was sent to Africa, and his cousin is still hospitalized in the PICU, and it seems that his life has been saved.

Be brave because you are afraid. Sun Lien clenched his fists and said firmly to Director Huang Wenhui, "I'll go in with you." ”

"Aren't you afraid?" Director Huang looked at Sun Lien's face, and suddenly asked with a smile, "It's a plague inside, and you're not married yet, are you?"

"My girlfriend is studying in the UK. Sun Lien almost gave himself a flag, but fortunately, he held back. "As for the plague...... I'm not afraid of losing face, of course I'm afraid. But what's the use of being afraid? I'm afraid that the patient will get better on his own?" he looked at Huang Wenhui and said seriously, "I'm an emergency doctor, and my job is to use all means to stabilize the patient's condition, and then transfer them to your specialist for further treatment." It's my profession. ”

Director Huang laughed after a while, she smiled very boldly, she raised her hand, reached Sun Lien's shoulder with a little difficulty, and then patted it vigorously, and praised in Cantonese, "Pretty boy!
