Coronavirus, it is not the virus with the highest lethal rate, not the most transmissible virus, or even the virus that has plagued the development of human medicine for the longest time. But the panic and social unrest it has caused are far more powerful than other viruses.

Taken together, there are five types of coronavirus that can cause illness among the dozens of types of coronaviruses. Symptoms can range from the most severe form of Middle East respiratory fever syndrome and SARS to the common upper respiratory tract symptom – cold and cough.

Coronaviruses are far less terrible than the filovirus family in terms of severity alone. But that doesn't stop it from becoming the virus that has caused the most public concern in the 21st century. The reason is also very simple, the virus infection is hidden, the incubation period is relatively long, and there is a fairly high fatality rate. By the time everyone notices the epidemic and starts personal protection, patients who have already been infected will continue to be reported. As a result, the illusion of "extremely contagious and ineffective defense with existing protective equipment and items" is formed in the eyes of people.

In the cross talk sketch, "SARS, AIDS, and cancer" coexist to describe "serious disease", and SARS still ranks first in it. This shows the vigilance and concern of the public about the coronavirus.

Not only the public is worried, but even the doctors are afraid. Viral pneumonia of unknown cause caused by various causes is a serious disease registered as a Class B infectious disease and managed as a Class A infectious disease in the national health system. Once all other causes have been ruled out and the patient must be suspected of having viral pneumonia of unknown cause, the hospital must take a sample and send the sample to a national laboratory for testing.

Sun Lien swallowed his saliva and said to Director Huang Wenhui, "Director Huang...... ...... you?" he was a little worried that Director Huang was going home or leaving the hospital, which would put others at risk of exposure. But...... Sun Lien himself did not have enough reason and excuse to stop Director Huang from leaving the hospital. The hint in the status bar is known only to him.

"You hurry up. When Director Huang saw Sun Lien coming, he waved his hand at him in a panic, and closed the door of the inpatient department, "We want to be quarantined here, you go quickly!"

Sun Lien saw that the door in front of him was pulled up by Director Huang with his thin arm, "Isolation?" he subconsciously asked, and then began to take two steps back.

"What?isolation?can't we go?" An old lady behind Director Huang suddenly raised her voice, "What do you mean?"

"There's a contagion here, and now the floor is quarantined. Auntie, are you here to visit the patient?" Director Huang beckoned to Sun Lien very covertly, pointed to the lock on the door, and then turned to the old lady behind him and said, "Which ward is your family in?

"What is the number of beds, get out of the way, I want to go out!" The old lady paused on the ground with her crutches, and was about to use her arm to pull away Director Huang who was blocking in front of her. Huang Wenhui is less than 1.6 meters tall, and her thin and short body was immediately dragged by the old lady. While trying to stabilize her body, she continued to stop in front of the door while shouting at Sun Lien, "Doctor Sun, lock the door!"

Sun Lien began to walk to the door after seeing Director Huang's movements, and when Huang Wenhui shouted, Sun Lien almost jumped out with the action of a goalkeeper to save, and locked the door of the respiratory medicine inpatient department with a "click".

"You're trying to hurt me!" The old lady watched Sun Lien's movements become completely angry, she pushed Huang Wenhui down, and then pulled the door a few times with all her strength. The two-tiered steel door was unmoved, and her attempt to smash the window with the crutches in her hand had little effect—there was a layer of barbed wire between the three layers of tempered glass, and she might have to wear her red panties outside to smash such thick glass with the crutches in her hand.

Director Huang Wenhui got up from the ground, and wanted to appease the old lady's emotions again, but ushered in a burst of angry insults, "You doctors don't treat people, why are you locking us up?!" The more she spoke, the more excited she became, and even ripped off the N95 mask on Director Huang Wenhui's face, and then spit on her face, "Still wearing a mask? If I die, you will die with me!"

Director Huang Wenhui closed his eyes tightly, wiped his face with the white coat on his body, and then opened his eyes. She sighed helplessly after watching a few nurses snatch the old lady away.

"Director Huang ......" Sun Lien's eyes were almost red when he looked outside the door, and he even felt that a stream of blood was rushing to his head, "I'll call the police......"

"No need. Huang Wenhui shook her head, "What's the use of calling the police now? She looked at Sun Lien, and then laughed, "Your emergency department has complete protective equipment, even goggles, can you give us some support?"

Sun Lien looked at the dark circles on Director Huang's face and the smile on his face, and his mood was extremely complicated. He nodded, "I'll go now." ”

"And. Director Huang smiled, "Let the canteen bring us food, now we can't order takeout." ”

The atmosphere in the Fourth Courtyard became tense. Three quarantines in two months made everyone's nerves tense. And this time the nature is completely different from the previous two.

The pathogen that led to the complete closure of the neurosurgery and respiratory medicine inpatient departments of the four hospitals is still "unknown".

"mNGS is already running. At the dean's meeting, Song Wen listened to the speech with a sinking face. There is no recognizable expression on a face. The directors of all the other departments sat together at the conference table with different expressions.

Zhao Weiguo, director of the laboratory department, is reporting to everyone, "Judging from the current PCR and routine test results, pathogenic sources such as influenza A and B, avian influenza, and adenovirus can be ruled out. However, the specific pathogen is still unknown. ”

"We've been in touch with the CDC. The director of the hospital infection department on the side interjected, "The staff of the disease control will come to take samples." However, if none of our four hospitals and colleges can test the results, there is little hope that the provincial disease control can find the pathogen. ”

The equipment of the Fourth Hospital and Ningyuan Medical College is far more advanced than that of the CDC. If they can't find the source of the problem themselves, then the provincial disease control will definitely not be able to find it. The difference in the generation of inspection equipment cannot be compensated for by the experience of the staff.

"How many patients are there now?" Song Wen lit a cigarette in her seat — she never usually smokes in meetings. "What are the symptoms?"

"There are currently three patients. Liu Pingchuan replied that all the doctors and nurses in his extraterrestrial department were quarantined. Now he is counted as a lonely person, "one after cerebral hemorrhage, and the remaining two are patients in the ICU." Symptoms are mainly focused on upper respiratory tract symptoms, low-grade fever, pulmonary imaging suggestive of viral pneumonia, and high levels of D-dimer and C-hypersensitivity proteins. ”

"In other words, three patients are not in a position to provide us with useful epidemiological survey data. Dean Song pondered for a moment and asked, "Who got sick first?"

"Patients with cerebral hemorrhage. Liu Pingchuan replied, "He was admitted to the hospital in an emergency room." On examination after admission, he did not show any upper respiratory tract symptoms. I also read the relevant inspection reports, and all of them are normal. ”

That is, the disease on his body was in the incubation period for both days. Dean Song frowned, "Are there any reports of infection among medical staff?"

Dr. Dong Xin of the Department of Neurosurgery and the 14 nurses who participated in the operation at that time had fever and headaches. Liu Pingchuan said solemnly, "Huang Wenhui, director of the Department of Respiratory Medicine, and the two doctors who participated in the consultation at the hospital's Infection Department have symptoms of dry cough and weakness. ”

Song Wen clenched the teacup in her hand tightly, "Sixteen medical staff, three patients......" She raised her head suddenly, "Report to the National Health Commission for payment, communicate with the Shanghai CDC, and send the samples over there for identification...... " She paused and continued, "Collect everyone's samples, and send them all to the P4 laboratory of the college!"
