Section Chief Tian handed over the rest of the sampling work to the rest of the district disease control and prevention department, and he trotted to follow Gu Yanan and his party.

"Director Gu, wait a minute, I have a situation to report to you here."

Section Chief Tian briefly talked to Gu Yanan about the epidemic situation reported by the doctor of Binhai Road Primary School on the phone.

After the report, Section Chief Tian asked worriedly, "Director Gu, the situation is serious now, a large number of teachers and students in Binhai Road Primary School are sick, and some students are so sick that they need to be hospitalized, do you think this will be an infectious disease?" ”

Gu Yanan frowned, thinking to himself, if Lu Li and the teachers and students of Binhai Road Primary School were sick for the same reason, then where was the source of infection? What is the causative agent?

"I'm not sure now, the flow of the Binhai Road Primary School will trouble Section Chief Tian, I'll take Lu Li to the hospital now, and by the way, take a look at the situation of the hospitalized students in Binhai Road Primary School."

"Okay, let's go our separate ways, Binhai Road Primary School is originally under the jurisdiction of our Binhai District Disease Control, our District Disease Control and Prevention will go to Binhai Road Primary School to do on-site investigation, I will contact you in time if there is any situation."

——

Lianhai First People's Hospital, Emergency Department.

Gu Yanan drove the on-site flow shunting car, and was originally going to take Lu to the Binhai District Hospital, which is the closest to the wetland park, but considering that the students who were hospitalized by ambulance at Binhai Road Primary School went to the best hospital in Lianhai City, the First People's Hospital, Gu Yanan temporarily changed the route and also went to the First People's Hospital.

When Gu Yanan and his party arrived at the emergency room, they found that it was overcrowded.

Xiao Chu helped Lu Li, looked at the crowd in the emergency room, and sighed: "What is the situation?" It's a weekday, why are there so many people in the emergency room? ”

Gu Yanan felt bad, and the number of patients in the emergency room suddenly increased, either because of a major accident or a major infectious disease.

Gu Yanan grabbed a little nurse who was busy running around and asked about the situation.

The little nurse was very impatient, "The family members who are not sick are waiting outside, don't you see so many patients?" They were all busy, and the idle people and others all withdrew outside the clinic. ”

Gu Yanan showed her work card, and the little nurse immediately changed her attitude, "Oh, these people are all symptoms of dermatitis, and it stands to reason that they should be hung up in the dermatology department, but the number of the dermatology department is full, so I came to hang the emergency department." ”

The little nurse saw Lu Li behind Gu Yanan, and the red-spotted pimples on his arms and neck were typical dermatitis symptoms this time.

The little nurse pointed to Lu Li and explained to Gu Yanan, "He is a typical symptom, and the people in this emergency room are basically like this." The doctor said that it was dermatitis, and it should be an allergy to something, but this kind of allergy phenomenon of a large number of people has never been discovered. You have to look into the cause. ”

Gu Yanan also noticed that the matter was serious, and asked the little nurse, "When did this happen?" That is, when did the emergency room start to see a large number of people with dermatitis? ”

"It started two days ago, and patients with this dermatitis phenomenon came to the dermatology department and the emergency room one after another. It's just that the number of people was relatively small before, and there are a lot of people today, and I don't know if the number of people will continue to increase in the future. ”

Gu Yanan pushed Lu Li to the little nurse's side, "Please help him deal with the rash on his body, at least relieve the symptoms of itching first, I will investigate the situation here, I hope to find the cause as soon as possible." ”

"Okay, leave the person to me, there is no special medicine, I can only use some external ointment to relieve the symptoms, I will help him rub the ointment first."

Xiao Chu and Wang Xiaoxiao stayed to accompany Lu Li, and Gu Yanan went to check on the situation of Zhang Xiaolan, a resident student at Binhai Road Primary School.

Soon, Gu Yanan found the ward where elementary school student Zhang Xiaolan was.

Zhang Xiaolan's parents had already heard the news and rushed to the hospital, and there were several doctors in the ward, including Gu Jiashu.

This is the ward of the Department of Respiratory Medicine, how could Gu Jiashu be here as the director of the Department of Infectious Diseases?

Seeing Gu Yanan enter the ward, Gu Jiashu was obviously stunned, and then reacted that the little sister may have come to investigate the epidemic situation at Binhai Road Primary School.

Several doctors in the ward were discussing Zhang Xiaolan's condition, and occasionally doctors were explaining something to Zhang Xiaolan's parents, Gu Yanan quietly approached her brother Gu Jiashu's side and asked in a low voice, "Brother, why are you here?" How is Zhang Xiaolan's situation? ”

"When I came to the consultation, Zhang Xiaolan's condition was basically stable, but no allergen was found, and the doctor in the respiratory department considered that the patient's sudden asthma asphyxia might be related to the infection, so he called me over for a consultation."

Gu Yanan looked at Zhang Xiaolan on the hospital bed, she was asleep, with a breathing mask on her face, and a vital signs monitor next to her, everything was stable.

Zhang Xiaolan's mother wiped her tears on the side, "My Xiaolan has always been in good health, she has never had asthma, and she has no allergies, and there are no seafood, pollen, peanut allergies and the like you are talking about." I don't know what happened this time, I sent her to school in the morning, but at noon I received a call from the school saying that the child was seriously ill and sent to the hospital. ”

Gu Yanan looked at Zhang Xiaolan on the hospital bed again, and found that she was sleeping with a few small red spots on her exposed arms, as well as on her neck, and in some places the red dots were one after another, like a wheal rash.

Judging from the skin symptoms alone, she has the same symptoms of dermatitis as the patients in the emergency room and Lu Li.

While listening to the conversation between the doctor and the patient's family, Gu Yanan whispered to his brother Gu Jiashu beside him, "Brother, why do you think Zhang Xiaolan suddenly had asthma asphyxia?" ”

Gu Jiashu approached Gu Yanan's ear and replied in the same whisper, "The allergens that caused Zhang Xiaolan's asthma asphyxia may be the same as those in the emergency room, Zhang Xiaolan also has dermatitis symptoms, everyone reacts to the same allergen differently, Zhang Xiaolan's reaction is more serious, and his classmate's symptoms are milder." ”

"Do you know what's going on at Corniche Elementary School and the emergency room?"

"I know some, it was her physical education teacher who sent Zhang Xiaolan to the hospital just now, and the physical education teacher also had dermatitis symptoms, the same as Xiaolan's symptoms, but the physical education teacher did not have asthma, and when the nurse was treating the dermatitis symptoms for this teacher, he said about the situation of Binhai Road Primary School, plus our hospital has recently admitted a large number of similar patients, so I suspect that everyone's dermatitis symptoms may be caused by the same allergen this time."

"Brother, what do you think allergens are? I know you haven't found a specific allergen yet, so you just have to speculate, not very specific, just a general direction. ”

Gu Jiashu thought for a while, "Judging from the patients who have just been treated in our hospital, there are people from all walks of life, and it has nothing to do with the occupation, age, or place of residence, so allergens should be accessible to everyone, and may exist in public environments such as air and water." ”
