Just like every time we eat together, my brother Gu Jiashu sandwiched her favorite fish cheek meat into a bowl for my little sister.

"Little sister, do you count your daily dating time in your working hours? Your ex-boyfriend Gu Qingcen is now your colleague, so work can be regarded as dating? ”

"Brother, don't talk nonsense, I don't have anything to do with Brother Qingcen now, it's just a simple colleague relationship."

"Really? He didn't want to see signs of a revival of old feelings? ”

Gu Yanan nodded seriously, "Really, Brother Qingcen works more seriously than me every day, except for work, we have almost no other communication in private." ”

"Didn't he move into the bachelor apartment you were in? In the same community, without the surveillance of his parents, he never went to you alone? ”

"No, although Brother Qingcen lives in the same community as me, he is not in the same building, he really hasn't looked for me, but occasionally when he goes to work in the morning, my relationship with Brother Qingcen seems to be more strange than before, and the estrangement of these 7 years is not so easy to eliminate."

"My silly sister, if she were an ordinary girl, she would probably ignore him for the rest of her life if she encountered something like that seven years ago. You're good, he came back and took the initiative to work in a unit with you, and you are still very happy. ”

"Brother, are you the same as your parents, and you still have a grudge against Brother Qingcen?"

Gu Jiashu didn't answer and asked: "Don't you blame him?" ”

Gu Yanan was stunned for two seconds, and then shook his head, "Even if it's not boyfriend and girlfriend, he's also our family, so ...... No complaints. ”

Gu Jiashu stared at the little sister, and after a long time, asked, "Did you ask the reason why he didn't say goodbye back then?" ”

"I asked, but Brother Qingcen didn't say, and I hope I won't ask again in the future. I knew he must have a grievance, a grievance that even the closest people didn't want to tell. ”

Gu Jiashu sighed, "My parents and I are a little resentful of Gu Qingcen's feelings, just because we treat him as a family member, so it hurt our hearts even more that he didn't say goodbye back then." ”

Gu Yanan turned his solemn expression and said with a smile: "Could this be the legendary resentment due to love?" ”

Gu Jiashu also smiled, "7 years have passed, and Gu Qingcen has become a topic of discussion between our brothers and sisters again. ”

Brother's words reminded Gu Yanan of the days when a family of 4 plus Gu Qingcen lived together 7 years ago.

At that time, the three children always had endless words, and Gu Qingcen also had a cheerful personality, always with a smile on his face.

Now that 7 years have passed, Gu Qingcen is back, although he still has a smile on his face, but this smile is not as clear as 7 years ago, with a little more warmth and sadness.

The mobile phone rang, pulling Gu Yanan's thoughts back from seven years ago.

The ringtone comes from Gu Jiashu's mobile phone.

After answering the mobile phone, Gu Jiashu's face was solemn.

"Brother, what's going on?"

"It's the hospital, the director of the neurology department Zhang Jianzhong's phone, said that their neurology department has received two more young patients transferred from other places, one is 8 months old, the other is one and a half years old, the symptoms are the same as Li Lele you mentioned before, there are skin and nervous system symptoms, and the preliminary diagnosis is unexplained encephalopathy."

Gu Yanan realized that something was serious.

There must be some connection between multiple patients with the same symptoms and unexplained diseases in succession.

"Brother, I'll go to the hospital with you."

——

Lianhai First People's Hospital, Department of Neurology.

The two young patients who were newly transferred to the hospital were placed in the same ward as Li Lele before.

The patient's family members stayed with him at the bedside.

When Gu Jiashu and Gu Yanan rushed to the ward, Zhang Jianzhong, director of the Department of Neurology, was arranging for doctors to treat the two young patients who had been newly transferred to the hospital.

Gu Jiashu asked Zhang Jianzhong quietly, "How is the situation?" ”

"Not very optimistic."

The 8-month-old patient had a sudden convulsion, and after emergency resuscitation, his condition stabilized slightly, but he was still admitted to the ICU.

The mother of the little patient stood in the corridor outside the ICU ward, looking anxious and haggard, and muttered quietly while waiting for her son's condition, "How can this be?" It's obviously cured, why is it suddenly serious again? ”

Gu Yanan retrieved the medical records of two newly transferred patients from the doctor's office.

Among them, the 8-month-old patient, who had been treated at the local county hospital two days ago, was discharged from the hospital after his condition improved, but today he suddenly recurred with high fever and convulsions, and entered the county hospital again.

The one-and-a-half-year-old patient also became ill two days ago, initially feeling listless, and then sent to the local county hospital for treatment with high fever and convulsions.

The two young patients and Li Lele belong to different geographical regions and different counties, and they usually do not intersect, why do they have the same symptoms one after another?

Are there any similar cases in other parts of Lianhai City?

What about places outside of Lianhai City?

A series of questions appeared in Gu Yanan's mind.

Without waiting for Gu Yanan to continue to think, Gu Jiashu took two tubes of cerebrospinal fluid specimens, "Little sister, these are cerebrospinal fluid specimens from two small patients who were newly transferred to the hospital, and your disease control will also help check whether it contains prions and confirm whether it is Creutzfeldt-Jakob disease." ”

"Okay."

——

Lianhai Center for Disease Control and Prevention, Emergency Office.

All six members of the emergency response team were present.

Gu Yanan immediately got the test reports of two newly transferred patients and Li Lele.

A negative prion test excludes Creutzfeldt-Jakob disease.

Colleagues in the laboratory also tested for various possible infectious pathogens at the request of Gu Yanan, and the results were all negative.

Regarding the etiological investigation of "encephalopathy of unknown cause", the investigation has entered a bottleneck.

Members of the emergency response team begin discussions in the office.

After discussion, several people agreed that poisoning was the most likely cause after the exclusion of various possible infectious agents.

However, there are many types of poisons, and it is not easy to detect specific poisons in patients.

Zhou Lao expressed his opinion, "Now no matter what kind of poison or which very rare infectious pathogen, we will first conduct a case investigation of each patient, and we can always find some clues." ”

Gao Fei agreed with Zhou Lao's opinion, "There are not many patients now, and there are only three cases for investigation, which should not be troublesome." ”

Lu Li also agrees with this approach, "Investigate the environment, the water you have drunk, the food you have eaten, and the things you have used before and after the onset of each little patient, and you will definitely find something." ”

Wang Xiaoxiao has already started to tidy up her things and is ready to go to the hospital to do a flow survey.

Everyone looked at Gu Yanan, waiting for her to make the next plan of action.

Gu Yanan stared at the computer screen on his desk with a slight frown.

Gu Qingcen noticed something unusual, "Yanan, what's wrong?" ”

Gu Yanan was checking the cases with related symptoms through the epidemic system on his computer, and found that in addition to the three patients at the First People's Hospital in Lianhai City, there were other hospitals that had treated or were treating similar patients.

"There are more than three patients, I only checked the case files in Lianhai City for the past month, and the online information shows that there are more than 30 patients with similar symptoms, ranging in age from two months to three years old, and a small number of these patients have been discharged, but most of them are still being treated in the hospital, and two of them have died."
