Lu Li picked up his mobile phone, "Sister Yanan, there is another epidemic?" ”

"Yes, there is an outbreak of suspected cluster parasitic infection, many people have been hospitalized, you go to the unit now to drive our disease control on-site flow shunting to the First People's Hospital, prepare the sampling box, and our hospital will meet."

Gu Yanan also sent a text message to the other members of the emergency team that the hospital would be together.

After arranging the task, Gu Yanan explained to Uncle Ge that he couldn't stay for lunch and had to leave.

Uncle Ge felt that it was a pity, but people had work to do, and he couldn't stop him as an old man, but after thinking about it, he immediately pushed Nan Han with a smile and flew to Gu Yanan.

"Let Han Fei send you there, Han Fei drives very steadily, and there are people on the road to talk to."

Nan Hanfei also responded, "Yanan, you didn't drive today, I'll send you." ”

Gu Yanan didn't refuse, the two walked out of Uncle Ge's courtyard, and when they arrived at the entrance of the alley where they parked, they found a familiar figure.

Gu Qingcen stood next to a black SUV, holding a small round flower pot with a small green succulent plant in one hand and a car key in the other.

The slender figure looked a little thin, and he smiled at Gu Yanan.

"Brother Qingcen, why are you here? I just called you in less than two minutes, and this new car can't be the one you just bought, right? ”

Gu Qingcen nodded slightly, "Well, I just went to pick up the new car in the morning, and on the way back, I wanted to buy a pot of green plants and put it on the desk, so I came to the flower and bird market here, and when I received a call from you on the way back, I turned around and came back to pick you up." ”

Gu Yanan felt that something was wrong, "How do you know I'm here?" I don't remember telling you the address. ”

"You didn't say the specific address, but you said that you would come to the flower and bird market with Captain Nan this Saturday to choose a red-billed firefinch for Uncle Ge, I have looked through the previous disease control files, one of the cases is about West African trypanosomiasis, Uncle Ge is one of the patients, and there is Uncle Ge's address in the file, so I know you are here."

Gu Yanan suddenly realized, "Oh, I almost forgot, Brother Qingcen has had the ability to never forget since he was a child." ”

There were members of the emergency team who came to pick him up, Gu Yanan pushed the plan to Nanhan to fly to the hospital, and went to the hospital together in Gu Qingcen's car.

——

Lianhai First People's Hospital, Department of Infectious Diseases.

Several patients with strange diseases in the neurology department have been transferred to the infectious disease unit.

Gu Jiashu was explaining the patient's situation to Lu Li, who arrived early.

Gu Yanan and Gu Qingcen appeared, and Gu Jiashu put the nematode at Li Jianzhu's autopsy in a jar, wrapped it in a transparent plastic bag, and handed it to Gu Yanan.

Gu Yanan glanced at it and instructed Lu Li, "Put it in the sampling box and go back to the colleagues in the parasite control institute for identification." ”

Lu Li took the autopsy specimen and put it in the sampling box, but his eyes kept looking into the ward of the ward, the entire infectious disease ward was already overcrowded, and there were really many people who got strange diseases this time.

Gu Yanan asked Gu Jiashu, "Brother, what about all the patients' cases?" ”

"It's all in my office, you can go and see it later, first tell me the types of specimens you need for disease control and parasite inspection, and I'll have people take samples and get the results as soon as possible."

"Feces, urine, blood, and cerebrospinal fluid."

"Okay, who's going to take a patient's specimen with the doctor? Who will follow me to see the case? ”

Gu Jiashu's gaze changed between Gu Yanan and Gu Qingcen.

"Brother Qingcen, you go and take samples with the doctor, and then send the specimens back to the laboratory, and notify me immediately after the results come out, I will see the cases in the hospital first, and then do the flow survey with the rest of the team." Gu Yanan instructed Gu Qingcen to start doing things.

"Okay."

In the ward, the doctor performs a lumbar puncture to remove cerebrospinal fluid.

The cerebrospinal fluid that was originally clear came out of the patient's body was a slightly white suspension.

After collecting the patient's specimen, Gu Qingcen hurriedly returned to the CDC laboratory.

Because it was Saturday, only one laboratory colleague arrived at the post, and there was a serious shortage of manpower, so Gu Qingcen decided to help and find a microscope to observe the patient's cerebrospinal fluid sample.

Under the microscope, small thread-like white worms wriggle in the cerebrospinal fluid.

According to the morphological characteristics of the insects, Gu Qingcen judged that it was the stage V larva of Angiostrongylus cantonensis.

The nematodes found in the pulmonary arteries of the deceased Li Jianzhu were adult Angiostrongyloides cantonensis.

Gu Qingcen asked his colleagues in the laboratory, "Does the laboratory have a serum kit to detect Angiostrongyloides cantonensis antibodies?" ”

Xiao Zhang, a young laboratory colleague, thought for a moment, "Before the parasite control institute was merged into the CDC, I would prepare some antibodies and serums for various parasites every year, and I went to the warehouse refrigerator to find it, and there should be a surplus reserve." ”

After some tossing, Xiao Zhang returned to the laboratory from the warehouse, holding a few sealed glass bottles in his hands, his face was excited, "I found it, there is a reserve, a year ago, it has not expired, this Guangzhou strongyloides is not common in our Lianhai City, these antibody detection serums were used for scientific research before, I didn't expect it to come in handy this time." ”

Antibody serum reagents are located, and all patient blood collected is examined.

Half an hour later, all the results were positive.

This indicates that the patients hospitalized with the "strange disease" are infected with Angiostrongyloides cantonensis.

After getting the laboratory test results, Gu Qingcen immediately called Gu Yanan.

When Gu Yanan heard the test results, he was just as he expected.

Gu Qingcen: "How are you in the hospital?" ”

Gu Yanan: "The rest of the group and I are doing a case study of each patient and have found some clues. ”

"What clues?"

"All the patients have participated in dinners outside, some are wedding banquets, some are conference buffets, some are class reunions, and the place of the dinner is at the Golden Bay Hotel in Dongcheng District, Lianhai City."

"Do you suspect that the patient was infected while having dinner at the Golden Bay Hotel?"

"Well, there are only a few ways to get Angiostrongylus cantonensis, drinking water contaminated with larvae, or eating an intermediate host of snails carrying stage III larvae, or coming into contact with the feces of infected mice, either way, it can only be determined after an examination at the Golden Bay Hotel."

Gu Qingcen's mind immediately appeared the location of the Golden Bay Hotel, "The on-site investigation should be sooner rather than later, I will go now." ”

Gu Qingcen was about to leave, but was stopped by Gu Yanan on the phone, "In order to avoid the situation of violently obstructing the execution of official duties like last time, this time I will contact the market supervision department first, and you have other things to do before you get in touch." ”

"What's the matter?"

"I think that the patients infected with Angiostrongyloides in Guangzhou this time are not only these in the First People's Hospital, there should be many similar cases in other hospitals in Lianhai City, you use my account to enter the medical networking system, check similar cases in other hospitals, sort out a list, and let each county CDC be responsible for the flow of patients in the jurisdiction."

"Okay."

"The account number and password are on the second page of the notebook in the first drawer of my desk."

"Well, I'll give you the news when I'm done. Also, if you want to go to the Golden Bay Hotel, remember to call me. ”

Gu Yanan remembered that the last time she was dealing with an outbreak of poisonous cucumbers contaminated with enterohaemorrhagic E. coli, the emergency response team went to the restaurant involved to take samples and was stopped outside the restaurant.

A scene turned into a group fight, Gu Qingcen received a lot of punches and kicks, if it wasn't for Nan Hanfei appearing in time, I don't know what the scene would have become.

The injuries on his body have not healed yet, and now he has to go to the hotel to do on-site investigations, and this time there can be no more violent incidents.
