"Funding is not a problem, our company can provide it, and the CDC needs to come forward to contact the sampling matters......"

Li Yiming was talking, the office landline phone on Gu Yanan's desk rang, and the caller ID was the number of his brother Gu Jiashu, and Gu Jiashu should be on business at this time.

"I'm sorry, I'll answer the phone first."

Gu Yanan gestured to Li Yiming, picked up the phone, and Gu Jiashu's anxious voice came from the other end of the phone.

"Little sister, a large number of suspected anthrax cases suddenly came to the emergency department of our hospital today."

"Anthrax? Is it just a clinical diagnosis, or is there already a laboratory basis? What is the approximate number of patients? ”

"There are no laboratory test results yet, but there is a high suspicion of anthrax in terms of clinical symptoms, and 16 patients have been admitted so far, but a large number of patients are still being sent in one after another."

Regardless of whether it is an anthrax outbreak this time, a large number of patients with similar symptoms are clustered, and it is already a cluster of cases, which requires the CDC to participate in the investigation.

Gu Yanan: "Okay, I will immediately bring the members of the emergency team over to conduct on-site investigation, and the patient's specimen will be sent to the disease control laboratory first." ”

Hanging up the phone, Li Yiming stood aside, just now he had heard Gu Yanan say the word "anthrax", knowing that there might be an outbreak of anthrax, he was doing scientific research, and he had not really encountered a plague investigation, and he was still a little panicked when he heard these two words.

Gu Yanan left Li Yiming's information on the table, "I'm sorry, there is an urgent disease control task today, and we will talk about scientific research cooperation projects later." ”

After sending Li Yiming away, Gu Yanan told the remaining two people in the emergency office about the epidemic call he had just received.

Wang Xiaoxiao asked in surprise: "Anthrax again?" The last time I encountered an anthrax epidemic was last spring, how could there be so many patients at once this time? Half of our emergency response team has gone to the county, should we call them back urgently? ”

Gu Yanan: "No, Xiao Chu and I went to the hospital to see the situation, and Xiaoxiao stayed in the office to stare at the report of similar cases in the big epidemic network." ”

——

Lianhai First People's Hospital, Ward C of Infectious Diseases.

It is a separate two-story building, and because of the temporary housing of a large number of suspected anthrax patients, the building is cordoned off by the hospital.

Gu Yanan and Xiao Chu wore protective clothing, showed their work cards, and entered the ward.

In the isolation ward, Gu Yanan examines the patient's symptoms.

Most patients have bruising of their hands and feet, and some patients still have black eschar on their hands, which is indeed gangrene.

However, some patients do not have bruising symptoms, and gastrointestinal symptoms such as nausea and vomiting are more intense.

Gu Yanan and Xiao Chu began to ask some basic flow questions about the patients who were conscious.

Coming out of the isolation ward, Gu Yanan and several doctors discussed the patient's condition.

"It's not like anthrax." Gu Yanan directly stated his inference, and then asked Gu Jiashu, "Are the results of the hospital's laboratory department out?" ”

"As soon as I came out, the blood test results showed that it was not a bacterial infection, the serological test results did not find anthrax antibodies, and the microscopic examination found whether Bacillus anthracis was found."

Another young doctor beside Gu Jiashu spoke, "It's not anthrax, there are several other bacteria that can cause gangrene. ”

Xiao Chu muttered quietly on the side, "The blood test results all say that it is not a bacterial infection, and it is useless to check for bacteria, so you have to check in other directions." ”

The young doctor stared at Xiao Chu and asked rhetorically, "Then in what direction to check?" Your CDC asked the patient questions for a long time, did you ask any clues? ”

Facing the young doctor's aggressive tone, Xiao Chu was a little angry, thinking that he only asked some basic flow questions just now, if the pathogen could be detected just by asking questions, then the disease control person would really become a god.

Xiao Chu was young and vigorous, and just wanted to reply to the young doctor a few words, but Gu Yanan preemptively said: "Through the inquiry of the patient just now, we found that the patient's work unit is different, and the place of residence is far away. ”

"Environment? Food? Do you suspect food poisoning? The young doctor asked.

"This possibility cannot be ruled out, and the specific cause needs to be investigated in detail with the life history of each patient to see what common exposure substances they have."

"What do you think could be causing the poisoning? The symptoms of the patients are too strange, the food poisoning patients who were admitted before were generally vomiting and diarrhea, either bacterial or viral, and occasionally there were a few food poisoning caused by chemical poisons, but I had never seen such a bruise and gangrene symptoms as today. The young doctor frowned and asked, the name of Gu Yanan has changed from you to you.

Xiao Chu: "Nitrite poisoning is also bruised all over the body, but there are too many toxins that can cause this symptom, and it is not realistic for the laboratory to investigate them one by one, we have to narrow them down to a range, and then it depends on our disease control." ”

Gu Yanan and Xiao Chu were about to leave, when suddenly a nurse hurriedly came over and shouted to Gu Jiashu, "Doctor Gu, there is an emergency situation in a patient's family, come and take a look." ”

Gu Jiashu and his party followed the little nurse to another isolation observation room and found a middle-aged woman lying on the ground.

She was lying on the ground, her hands scratching her skin frantically, blood marks had appeared on her body, and her mouth kept shouting, "Bugs, so many bugs are biting me......"

Several male doctors stepped forward to control the middle-aged woman's hands to prevent her from scratching herself, and Gu Jiashu found that there were no bugs on her body after examination.

It's an illusion!

It seems that the toxin has begun to attack her nervous system.

Her hands and feet also began to bruise, showing symptoms similar to those of other patients in the isolation ward at the beginning.

Gu Jiashu recognized her, she was the wife of the patient Wang Yunhao.

In addition to symptoms similar to those of other patients, she also experienced hallucinations, which were new.

Gu Yanan and Gu Jiashu glanced at each other, although there were new symptoms, it was also a clue.

Several people worked together to help Wang Yunhao's wife Li Xiaoya to the hospital bed, and after taking the medicine, Li Xiaoya was temporarily awake, and Gu Yanan asked her a few questions.

Where do you live? What is the profession? What have you eaten recently and what special environments have you been exposed to?

After Li Xiaoya answered one by one, she talked about the experience she felt was more important, "Doctor, I just felt that there were thousands of ants on me, and my husband also said that he was in pain when he was sick, but he didn't say that it was like a bug biting. Also, before my husband and his second uncle became ill, several pigs died in my family, could it be that the pigs passed the disease to us? ”

The death of pigs in the patient's home is a zoonotic disease?

This is another new clue.

Gu Yanan did not answer Li Xiaoya's question directly, but told her that she wanted to go to her house to investigate, and Li Xiaoya told Gu Yanan the location of the key at home.

After the inquiry in the ward, Gu Yanan and Gu Jiashu discussed the patient's condition for a while, and decided to act separately, Gu Jiashu is responsible for treating the patient symptomatically, and if a new patient is sent, he will be questioned according to the case questionnaire left by Gu Yanan, and the news will be fed back to the CDC in time. Gu Yanan led the emergency team to the patient's home to conduct on-site investigation.
