The physical education teacher wanted to ask another question, but suddenly heard another physical education teacher's shout from the door, "Doctor, many students in the class are in pain, can you show me what is going on?" ”

Immediately afterwards, a group of elementary school students cheered into the school infirmary.

The old school doctor looked stunned, so many students are sick?

"What's wrong with it?" The old school doctor stood up, looked at the group of small people in front of him, and asked.

Dozens of students crowded into the school infirmary, and it was like an explosion of the pot at every word, and I couldn't hear what they were saying at all.

The old school doctor made a stop gesture, "There are students who are not feeling well in a line, and they come over one by one to check." ”

With the help of the PE teacher, dozens of students lined up in a line.

Although the line was lined up in multiple curves and S-shapes as much as possible, some students still lined up at the door of the school infirmary.

The old school doctor examined the students one by one.

After examining a few of them, he found that these students all had a sudden onset, the affected area was itchy and unbearable, some students also had a slight spicy pain, and after scratching, the skin appeared light red spots, pimples, and some had rubella masses.

These are all symptoms of dermatitis.

Dermatitis mainly occurs in the head and neck, exposed parts of the upper limb surface, and some students have dermatitis that spreads to the chest and abdomen.

The old school doctor's face became heavier and heavier, and he examined a dozen more students and found that their symptoms were basically similar.

Everyone's constitution is different, if it is an allergy such as pollen or mites, will there be such a large range of student dermatitis at the same time?

If it was a mosquito bite, no wounds were found on the skin.

"With so many people getting sick at the same time, it can't be a contagious disease, right?" One of the PE teachers scratched his arm and asked the old school doctor worriedly.

"I'll look at your arm." The old school doctor noticed the abnormality of the physical education teacher and took the initiative to ask him to stretch out his arm to check.

The teacher also had dermatitis symptoms similar to those of the student on his arms, erythema and papules.

Generally, children are allergic to many things, but as the body develops and the immune system is healthy, adults will be less allergic. However, the physical education teacher in front of him, who was in very good health, also showed symptoms of dermatitis, and the old school doctor began to doubt his previous inference.

Isn't it allergies? Is it an infectious disease?

Both the old school doctor and the physical education teacher were skeptical.

Suddenly, a little girl lined up outside the door of the school infirmary fell to the ground with her hands on her neck.

A little bespectacled boy standing behind her shouted in fear, "Zhang Xiaolan fainted......

The old school doctor rushed out of the school infirmary, and saw a little girl lying on the ground, her hands on her neck, her face purple, and a sound like a rooster crow coming from her throat.

"Oh no, she's suffocating."

The old school doctor hurriedly carried the little girl to the hospital bed in the infirmary, found the asthma spray from the drawer, sprayed it twice into the mouth, and the symptoms were not relieved, and found a syringe full of medicine from the cabinet and gave the little girl an intravenous bolus.

The rooster crow in the little girl's throat was not so sharp, but her face was still purple, and although the suffocation symptoms had been relieved, she still looked uncomfortable.

The old school doctor was helpless, and could not find the cause of the allergy, and the effect of symptomatic treatment was not obvious.

If it drags on like this, the other children may be fine, but the little girl in front of her, who has developed allergic asphyxia asthma, will be in danger.

"Call 120 and send you to the hospital." While observing the little girl's symptoms, the old school doctor asked the physical education teacher who was guarding next to her to call an ambulance.

Soon, the ambulance roared in and stopped downstairs in the school infirmary.

The little girl with asthmatic choking was carried into an ambulance by paramedics.

The old school doctor instructed the physical education teacher who had an itchy arm, "The parents of the students will not be able to make it for a while, you go to the hospital with the ambulance, and let the doctor show you your arm by the way." ”

The PE teacher happily agreed, jumped into the ambulance, and rushed to the hospital with the ambulance unhindered.

The ambulance left, leaving only the old school doctor and another physical education teacher in the school infirmary, looking at a large group of students with mild and severe symptoms, feeling big.

The PE teacher leaned over to the old school doctor's ear and whispered, "What about the rest of the students?" Should I be sent to the hospital? If it is an infectious disease, then other students may also have serious symptoms like Zhang Xiaolan, even if it is not an infectious disease, it is other reasons that cause the students to get sick, and we can't find out the cause of the illness, what should we do now? ”

It was the first time that the old school doctor had encountered this situation for so many years, and according to previous experience, occasionally students with allergies came to the school infirmary to take some anti-allergy medicine and apply some ointment.

It is the first time that I have encountered such a serious allergy situation, and so many students have the same disease.

The old school doctor couldn't make up his mind, and finally squeezed out a sentence, "Report to the school leaders." ”

The school leaders have no medical background, and they do not have as much medical knowledge as the old school doctors, so they are also panicked when they encounter this situation, thinking that if the students have three strengths and two weaknesses, they will stop doing it as a school leader, and maybe they will have a lawsuit.

The school leaders thought about it for a while, and suddenly remembered that there had been cases of large-scale illness of students in the school before, and in the past, there would be a cluster of flu outbreaks in winter and spring, and many students would be affected, and they would report to the CDC at that time.

Now there are many students who are sick, and although the symptoms are not flu, it is also a cluster outbreak, whether it is an infectious disease or not, it is always right to report to the CDC.

The school leader gave an order to the old school doctor, "Call the CDC, tell them about the situation in the school, and let the CDC send someone to investigate." ”

Lianhai City, Binhai District, Crescent Bay Wetland Park.

In the park's grove, several disease control workers in protective suits collect stagnant waterfowl from the lake.

Gu Yanan, Lu Li, Xiao Chu, Wang Xiaoxiao, and 5 staff members of Binhai District Disease Control and Prevention are among them.

Since the outbreak of the West Nile virus in the Crescent Bay Wetland Park some time ago, although the epidemic has been controlled, but within a few days, a large number of dead waterfowl appeared around the lake in the wetland park, and after preliminary testing, the cause of death of waterfowl was infected with H5N2 subtype avian influenza.

Although the H5N2 subtype of avian influenza does not infect humans, it does not rule out the possibility of virus mutation, and in case of mutation, it may also cross the racial barrier and enter the human epidemic from birds, so CDC should monitor the epidemic of avian influenza in wild birds and waterfowl, and collecting wild birds and wild waterfowl in the wild is one of the daily tasks of disease control.

Every year during the avian influenza season, Gu Yanan's emergency response team goes to various counties and districts to guide the collection of local wildlife samples.

According to the experience of previous years, the distribution pattern of influenza among wild birds and waterfowl in various counties and districts of Lianhai City is different, and the natural environment in some places is particularly prone to wild birds and other wild animals, especially near the Yuntai Mountains and the coastal wetland park.
