Xiao Wu, a community policeman, heard the words of the emergency doctor, and his heart trembled, "Doctor, this disease is very serious?" ”

"Are you asking about hepatitis A or hepatic encephalopathy? Hepatitis A mortality is not high, but hepatic encephalopathy, a complication of hepatitis A, has a high mortality rate. ”

Xiao Wu also wanted to ask some questions about the proprietress's condition, but the little nurse on the side urged, "The family should go and pay the money and go through the hospitalization procedures." ”

Xiao Wu is hesitating, if according to what the emergency doctor just said, the proprietress is a hepatic encephalopathy caused by hepatitis A virus infection, then there is a risk of death, and her only relative must be notified at this time, otherwise the consequences are not something that he can bear as an outsider.

The little nurse was still urging, and Xiao Wu, the community policeman, promised again and again, "Okay, okay, I'll pay the money immediately, you treat the patient first, and I will also inform the patient's daughter to take the patient's ID card and medical insurance card." ”

Xiao Wu was busy contacting his family and going through the hospitalization procedures, and Nan Hanfei came to the infection department with the boss's mobile bed.

The infection department is Gu Jiashu's territory, and at the entrance of the ward, Nan Hanfei and Gu Jiashu have a face-to-face.

Gu Jiashu was obviously stunned, looked at the patient, then looked at Nan Hanfei, and asked, "The patient is your friend?" ”

"No, I was having dinner with a friend at her shop, and she suddenly fell ill, and I sent her to the hospital."

"Oh, I'll take care of the rest, and you can just inform your family."

Nan Hanfei is still not at ease, according to the words of the emergency doctor just now, the proprietress and several patients before should be hepatitis A, and suddenly there are hepatitis A patients clustered, where is the source of infection?

Hepatitis A is a statutory Class B infectious disease, the hospital will report it in time, and the CDC will send someone to investigate.

Thinking of Gu Yanan, Nan Hanfei was a little dazed.

Nan Hanfei's strange appearance fell in Gu Jiashu's eyes, Gu Jiashu knew the relationship between Nan Hanfei and his little sister Gu Yanan, if he had to choose someone for his little sister to accompany him until he was old, Nan Hanfei in front of him was indeed a good candidate.

Gu Jiashu: "This patient has positive hepatitis A virus antibody IgM in her blood, which means that she has been infected with hepatitis A not long ago, if you have been in close contact with the patient or have eaten the food prepared by the patient, it is best to go and check it." ”

Nan Hanfei could feel the concern in Gu Jiashu's words, "Okay, I'll let my friend go for a checkup, I should be fine, I have been vaccinated against hepatitis A, and I have a certain amount of resistance......"

Before Nan Hanfei finished speaking, his mobile phone rang urgently.

Caller ID police officer Xiao Li.

Nan Hanfei waved goodbye to Gu Jiashu, turned around and went to answer the phone in the corner outside the ward.

Xiao Li's voice came from the phone, "South team, the autopsy report of the murder of the 'Mermaid Seafood Shop' in the food street next to Binhai View Avenue has come out, and the cause of death is stomach bleeding, and the blood spit out is sucked into the lungs, resulting in suffocation and death."

In addition, the deceased also had slight cerebral edema and liver necrosis. Even if he hadn't been pushed by the tattooed client, he was terminally ill. ”

Nan Hanfei thought that the symptoms of the deceased and the proprietress were very similar, and they both worked in a seafood restaurant, could they be infected with the same pathogen?

"Xiao Li, let the forensic department check the pathogen in the deceased's body, focusing on the hepatitis A virus."

"Hepatitis A? Team South, do you suspect that the deceased was a hepatitis A patient? ”

"Well, the initial suspicion may be that finding out the cause is also an explanation to the family of the deceased, and it is also a reference basis for the court to sentence the tattooed client."

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan received a call from his brother Gu Jiashu, "Little sister, our infectious disease department has confirmed another case of acute hepatitis A patient, his information I am entering into the big epidemic system, plus the previous dozen cases, I think the incidence of hepatitis A has been high recently, although these cases of hepatitis A patients admitted to our hospital have no connection, but it is not ruled out that they may have been exposed to some common sources of infection, I can't see the incidence of hepatitis A in the city, but you can see it in the disease control system, and you can summarize accurate statistics. Do you think this is a hepatitis A outbreak? ”

Gu Yanan picked up the phone with one hand, controlled the computer mouse with the other, looked at the statistics on the computer screen, and said in a rather dignified tone, "I have just sorted out the statistics of the past two days, and the incidence of hepatitis A in our Lianhai City has been much higher than that of the same period in previous years, and the difference is statistically different. ”

Gu Jiashu heard Xiaomei say that the CDC had begun an investigation, and his hanging heart calmed down a little, after all, if the source of infection cannot be found, more and more people will be infected, and the infectious disease department is now crowded with patients in the acute stage of hepatitis A, if the number of patients increases, it will exceed the hospital's capacity.

Hanging up the phone, Gu Yanan stared at the report cards that popped up on the computer screen one after another, all of which were hepatitis A cases reported by various hospitals through the epidemic system, and these cases were distributed in all corners of Lianhai City.

So far, there have been about 200 cases.

Wang Xiaoxiao stared at the report cards that popped up continuously on the computer screen, and her expression was already dumbfounded.

Wang Xiaoxiao has never seen a hepatitis A outbreak of this scale, even Zhou Lao, who has the longest work experience, has never seen it, which has broken the record of the scale of hepatitis A outbreak in the history of Lianhai City.

Gu Yanan stood up from his desk and reached out to gently support Wang's chin with a smile, "Don't be surprised, start working." ”

Gu Yanan began to assign work, "The hepatitis A virus is mainly transmitted through the fecal-oral route, and the outbreak is most likely to be caused by contaminated water or food, Zhou Lao and Gao Fei went to check the city's recent water quality, including factory water, pipe network water, direct drinking water, and water quality from water sources, the incubation period of hepatitis A is generally about 30 days, so you have to check the water quality of the city in the past month."

Lu Li and Wang Xiaoxiao followed up on the case investigation of hepatitis A patients in various counties and districts, because the number of hepatitis A patients is relatively large this time, you go to various hospitals for guidance, and pay attention to the common points of the patients' contact experience.

All the information is fed back to me in a timely manner, and I will do the statistical analysis. ”

Everybody's busy.

Gu Yanan was the only one left in the emergency office.

Gu Yanan continued to sort out the information on hepatitis A cases reported online by various hospitals, and the landline bell on his desk rang.

Gu Yanan picked up the phone, thinking that it would be a call from the hospital to inquire about the hepatitis A epidemic just now, but when he heard the voice on the phone, Gu Yanan was shocked.

It was Nan Hanfei who called.

In the past, Nan Hanfei contacted her through her mobile phone, why did she suddenly use the office phone on the desk today?

Since the last time Nan Hanfei sent her a "fateful" text message, she didn't reply, and the two haven't been in touch for many days.

Gu Yanan felt that Nan Hanfei should have given up, but he didn't expect to receive a call from him again today, and it was an office call.

Gu Yanan was a little nervous in her heart, nervous that Nan Hanfei would bring up the "destined" private matter.

On the phone, Nan Hanfei directly explained, "Yanan, there is a deceased person on my side, and the forensic department has just found out that the cause of death is upper gastrointestinal bleeding caused by hepatitis A virus infection, and the blood was sucked into the lungs and suffocated.

I know that your CDC is investigating this hepatitis A outbreak recently, and I will send you the information of the deceased, hoping that it will be helpful for you to investigate the source of infection. ”
