Lianhai First People's Hospital, Department of Cardiac Surgery.

Accompanied by her family and Gu's father and Gu's mother, Mrs. Li found the attending doctor who had performed heart surgery.

The doctor first gave Mrs. Li a heart color ultrasound.

The heart is normal and the recovery is good.

But Mrs. Li has a high fever and vomiting symptoms, is it food poisoning?

After further examination, it was found that Mrs. Li still had symptoms of neck stiffness.

"Blood and cerebrospinal fluid draws."

Bright red blood flows into the blood collection tube, and nothing unusual can be seen with the naked eye.

This is followed by cerebrospinal fluid aspiration.

As the milky white and cloudy cerebrospinal fluid flowed out, everyone present was taken aback.

Gu's mother has worked as a nurse for many years and knows what that means.

"There is an infection! It's so serious! Gu's mother exclaimed.

The cardiac surgeon contacted Gu Jiashu by phone, "Dr. Gu, I have a meningitis patient here who needs to be transferred to the infection department. ”

——

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

Old man Zhang, who was admitted to the hospital first, and Mrs. Li, who was admitted later, were arranged in two adjacent wards.

Gu's mother is very concerned about the situation of the two neighbors, and it just so happens that the attending doctor of the two is her son Gu Jiashu, so it is convenient to ask.

"How's they doing?" Gu's mother asked Gu Jiashu in the doctor's office.

"Both of them have symptoms of meningitis and pneumonia, judging from the situation of cerebrospinal fluid, it is a bacterial infection, and antibiotic treatment has begun, and the treatment effect is still uncertain, and the type of antibiotics will be adjusted by waiting for the pathogen test results of the laboratory department." Gu Jiashu naturally told the truth to his mother.

"In addition to meningitis, there is pneumonia? No wonder both coughed. ”

Gu's father has been busy with Gu's mother, but at this time, he suddenly became idle, but he coughed again and again.

"Old man, why do you cough so badly? Did you get tired of running before and after running just now? "Gu's mother is more concerned about Gu's father's body.

Dad Gu shook his head, "Don't you know me, as soon as winter enters this year, I have an intermittent cough, it should be the old problem of chronic bronchitis again, sometimes good and sometimes bad, but it has been a little more serious in the past few days, and it is not in the way." ”

When Gu Jiashu heard his father's words, he was worried and blamed himself, as a son, he was busy in the hospital all day, and he didn't know that his father had been sick for so long.

"Dad, since you're here today, let's do a full body examination to see what went wrong, and treat the cause to get to the root of the disease."

Gu's father didn't want to trouble his son, so he shirked it again and again, but he couldn't resist Gu Jiashu's insistence, and finally obediently went to do various examinations.

A series of imaging tests came out, among which the chest X-ray showed that Gu's father had mild pneumonia.

"Dad, you have pneumonia and need to be hospitalized."

Gu's father and Gu's mother were stunned.

Send someone to the hospital, and in the end, you have to be hospitalized yourself?

Gu's father asked, "I'm just coughing, and I still need to be hospitalized?" You still prescribe some medicine and I'll go back to take it, we don't occupy public medical resources. ”

Gu's mother was a little shaken, she had always thought that her old man had a recurrence of bronchitis, but she didn't expect it to reach the point of being hospitalized, and since it was requested by her son, there must be a reason for him.

Gu's mother asked: "Kashu, what's the matter with your father's pneumonia?" Serious enough to require hospitalization? ”

Gu Jiashu patiently explained, "If it is pneumonia caused by a common cold, it is not a big deal, but my father's film is different from the film of pneumonia caused by a cold, and the current situation is the same as the lung images of the two patients just now." ”

Gu's mother and Gu's father looked at each other, and they understood what their son's words just now meant.

If Dad Gu is really infected with the same pathogen as Old Man Zhang and Mrs. Li, then it is very likely that the same symptoms of meningitis will occur next.

Gu's mother: "I'll be hospitalized now, your dad has been in poor health recently, and he must be discharged after being cured this time." ”

An hour later, the hospital laboratory department.

Several new cerebrospinal fluid and lung wash fluid specimens from the Department of Infectious Diseases have begun to stain and examine under the microscope.

Under several different staining methods, cocci with a wide and thick capsular can be seen in patient specimens.

Gram stain, purple budding cocci under the microscope, and spores in the central fovea.

Direct microscopic examination can determine that the causative agent is a fungus.

The laboratory department first informed Gu Jiashu of the preliminary discovery, which pathogenic fungus it was, and further purified and cultured it for biochemical identification and typing.

Gu Jiashu looked at the test sheet and thought to himself, there are many fungi that can cause meningitis and pneumonia, no matter which one it is, the patient should be given antifungal drugs first.

It's just how this fungus can infect multiple patients at the same time? And the patients all live in the same community.

Since it is a mass disease of unknown cause, it should be reported to the CDC.

Gu Jiashu dialed the little sister's number.

——

Lianhai Center for Disease Control and Prevention, Emergency Office.

The six members of the emergency response team are busy in the office.

Because of the last human infection with Streptococcus suis epidemic, Lu Li is collecting popular science materials and preparing to send them to the center's website with Gu Yanan's popular science circle of friends.

Wang Xiaoxiao is sorting out routine monitoring data.

Zhou Lao and Gao Fei are discussing the problems they encountered in the last time they guided the local rat density survey in Qingcheng Mountain.

Gu Yanan analyzes the results of previous virus sequencing on a computer.

Xiao Chu sat opposite Gu Yanan, in a daze again.

Since Xiao Chu's elder brother Chu Qingfeng moved to Xinhua Apartment to be Gu Yanan's downstairs neighbor, Xiao Chu's number of dazes in the office has increased significantly.

The voice of the phone on the desk rang, Xiao Chu came back to his senses, and immediately got up to answer the phone.

The call was from Gu Jiashu, Xiao Chu had seen Gu Jiashu a few times and remembered his voice.

"Doctor Gu? Are you looking for Sister Yanan? ”

"Well, we have several patients in our hospital, all with similar symptoms, and I suspect that there is a cluster of cases of pneumoniae meningitis caused by some kind of fungus."

"Oh, I'll let Sister Yanan listen to the phone."

Gu Yanan took the phone, listened to his brother Gu Jiashu talk about the matter, and asked: "The same fungus was found in the cerebrospinal fluid and lung wash fluid of the three patients?" ”

"At present, it is only observed under the microscope, and from the results of the microscopic examination, it should be the same fungus, but it will take some time to classify the specific species, and I am worried that this fungus is highly contagious, so I will call you."

"Help with testing?"

"Well, it's more important to find out the source of infection, because all the patients are currently from the Xinhai Garden Community."

"Xinhai Garden Community?! Where do mom and dad live? ”

"Well, and my dad is the third patient who has developed pneumonia, but not meningitis."

"Why didn't you say it earlier! I'll go over right now. ”

After Gu Yanan hung up the phone, he rushed to start preparing the sampling box.

Xiao Chu had never seen Gu Yanan so nervous, so he followed her and asked, "Sister Yanan, what happened?" ”

"There is a cluster of encephalitis of unknown cause in the First People's Hospital, and I have to go over to investigate."

"I'll go too." Xiao Chu took the initiative to ask.

Xiao Chu knew that what could make Gu Yanan so nervous must be a big deal.

This learning opportunity, he could not miss.

"Okay, Xiao Chu will go to the hospital with me, and Zhou Lao, Gao Fei and Lu will leave the scene and go to the Xinhai Garden Community."

Gu Yanan assigned tasks to everyone, and Wang Xiaoxiao was left with a task that was not mentioned.
