The whole day of the survey process went smoothly, and in the evening, the afterglow of the setting sun sprinkled on the lake, and several members of the survey team returned to the engineering vehicle at the foot of Kongwang Mountain, ready to return to the city.

On the way back, Xiao Li couldn't help but sigh, "Fortunately, everything went well, and after this survey report is handed in, I want to take a long vacation." ”

Captain Lao Zhang sat in the co-pilot's seat, the open window blew in a cool breeze, he couldn't help but shiver, "You send me all the data you have surveyed, and I will hand it in next Monday after I make a summary." ”

Two days later, on Monday morning.

Lao Zhang went to the unit to hand in Friday's survey report.

In the leader's office, Lao Zhang coughed while explaining the contents of the report.

The leader frowned and asked worriedly, "Lao Zhang, are you sick?" ”

"Ahem, ahem...... A small cold, out of the way, had a little cough last night and started to have a fever when I woke up this morning. ”

"Lao Zhang, you have to pay attention to your body, it's not easy to get a cold in summer."

"Well, I also feel that this cold is particularly uncomfortable, the headache is terrible, and the whole body hurts, if I don't have to hand in the survey report today, I will rest at home, and now the report is also handed over to you, I want to take two days of sick leave."

"Okay, go back and get some rest."

Coming out of the leader's office, Lao Zhang was very uncomfortable, and he wanted to go home to rest after taking sick leave, but now it is better to go to the hospital in this situation.

Lao Zhang made up his mind and prepared to take a taxi to a nearby hospital, but it was very difficult to walk down the stairs, and his two feet did not obey him.

He held on to the wall with both hands and tried to grope his way down the stairs, but his feet were weak, his eyes were dark, and his head was down, rolling from the top floor to the bottom of the stairs.

The office building was full of people, and someone fell down the stairs, which immediately attracted a crowd of onlookers.

Lao Zhang fell at the top of the stairs, convulsive, and there were blood stains on his forehead.

"Oh no, someone fell down the stairs."

"Isn't this the old Zhang of the survey team?"

"It's Lao Zhang, why did you fall down the stairs and get pumping?"

"Don't talk about it, call 120."

Lianhai First People's Hospital, emergency room.

Lao Zhang was lying on the hospital bed.

The colleague who sent Lao Zhang had already called his family to inform him, and Lao Zhang's family was also staying by the bedside at this time.

The emergency doctor is examining Lao Zhang.

The patient was hot, and the nurse brought a thermometer to measure it at 40.2 degrees Celsius.

The eyelids were opened to examine the pupils, and there was tremor and paroxysmal convulsions of the limbs.

Examination of the neck, limited movement, is a symptom of nuchal rigidity.

Meningitis?!

Viral? Or is it bacterial?

This season, most of it is viral meningitis B.

The emergency physician aspirates the cerebrospinal fluid (CSF) of the patient.

The slender needle pokes into the spine, and a clear fluid soon flows out.

From the characteristics of cerebrospinal fluid, bacterial meningitis can be basically ruled out.

Carefully inspect the patient's face and hands, and there are large and small red spots on them, which are traces left by mosquito bites.

"There is a high suspicion of Japanese encephalitis, and the patient is sent to the infectious disease department."

Regarding the emergency doctor's arrangement, the patient's family was full of questions, "Doctor, didn't my husband fall down the stairs?" How did it become JE? ”

"Rolling down the stairs and falling out of a high body temperature of more than 40 degrees, he now has typical symptoms of meningitis, and there are traces of mosquito bites on his body, which indicate that the patient may be Japanese encephalitis, but to confirm the diagnosis, laboratory tests are needed, and now he is transferred to the infectious disease department, and the doctor will treat him symptomatically. If JE is left untreated, recovery is poor. Why are you bringing patients to the hospital now? ”

The family members are still very puzzled, yesterday the person was fine, today I went to the unit to report my work, why did it become a serious illness and hospitalized?

"Doctor, my husband was fine when he went out in the morning, why did he become JE when he came to the hospital now?"

"The patient did not have a fever before being admitted?" The emergency doctor asked the family with a frown while going through the procedures for transferring departments.

"When I went out in the morning, I had a little fever and took some cold medicine, and my husband said that a small cold was not in the way."

The emergency doctor prescribed the hospitalization list, "Hurry up and go through the hospitalization procedures, don't delay, the initial symptoms of many serious diseases are like a cold, don't worry too much, according to the current level of medical care, this is not an incurable disease." ”

The emergency doctor wanted to comfort the anxious family members, but when they heard this, the family's ears became even more panicked.

——

Infectious Disease Ward.

Gu Jiashu, as the attending doctor of the patient Lao Zhang, gave medical advice according to his symptoms and treated the symptoms.

After antiviral treatment, Lao Zhang's symptoms eased slightly.

Soon, Gu Jiashu got the test report from the laboratory department.

JE virus was not detected in the cerebrospinal fluid of patient Lao Zhang.

Not JE!

However, judging from the patient's blood count, it is a viral infection.

Gu Jiashu was about to ask the laboratory department to do several other virus antibody tests, when suddenly, he received a call from the emergency department.

"Doctor Gu, there is another patient with meningitis in the emergency room, and his symptoms are very similar to Lao Zhang, a patient who was transferred to the infection department just now. The families of the two patients knew each other, and I asked the families of the patients only to find out that the two patients were colleagues. When the emergency doctor was talking to Gu Jiashu, he deliberately accentuated the tone that the two people were colleagues.

Gu Jiashu chuckled in his heart, could it be a cluster case?

It has not yet been detected which pathogen it is, and new cases have appeared, which is not a good sign.

The new patient was soon transferred to the Infectious Diseases Unit.

Gu Jiashu looked through the information of the newly transferred patients and found that the patient's name was Xiao Li, who worked in the same unit as Lao Zhang, a patient who had previously entered the infectious disease ward.

Xiao Li had mild symptoms of meningitis, but his consciousness was relatively clear, and he only had fever and vomiting.

Lao Zhang and Xiao Li were placed in the same ward.

Gu Jiashu seized the opportunity to ask Xiao Li about his experience before he fell ill, especially his experience with Lao Zhang.

"Xiao Li, what experiences did you and your colleague Lao Zhang have in common before they got sick? For example, do you sit in an office? Have you ever had a meeting in the same place? Have you ever been to some common place at work? Is there anything special about the co-working environment, such as mosquitoes......"

Without waiting for Gu Jiashu to finish asking, Xiao Li looked at Lao Zhang, who was unconscious on the hospital bed next to him, he was already terrified, the current Lao Zhang may be his future end, he didn't want to lie on the hospital bed in such a coma, maybe he would die.

He hurriedly told the attending doctor, Gu Jiashu, "Last Friday, Lao Zhang and a few members of the survey team went to the Crescent Bay Wetland Park near Kongwang Mountain to do a survey, and found a lot of dead birds in the wetland, and I also touched those dead birds with my hands. ”

Avian flu?!

Both patients now have severe respiratory symptoms in addition to meningitis.

In the past, there have been several cases of human infection with avian influenza in Haishi, but they are all individual cases, and there are no clusters of concentrated outbreaks.

In such a serious situation, Gu Jiashu didn't have time to fill in the information on the Internet about infectious diseases, so he immediately called his little sister Gu Yanan first.
