Gu Yanan asked Section Chief Pang to send the medical records of the villagers of Lijia Village who were hospitalized in the county hospital to her email, and she carefully looked at each patient's symptoms.

The symptoms of one of the villagers caught Gu Yanan's attention.

The patient, a 48-year-old villager from Lijia Village, had abdominal pain 5 days ago with no obvious cause, mainly in the upper abdomen, persistent dull pain, nausea, no vomiting, local swelling of the right neck, coughing up sputum, the sputum is yellow, viscous, not easy to cough up, and there is no coughing up blood.

Fever as high as 39 degrees Celsius, chills, chest tightness and shortness of breath, sweating all over the body, soreness in both legs in the past two days, difficulty walking.

At the county hospital, chest CT showed multiple inflammation of both lungs, multiple lymph nodes in both axillas, a small amount of fluid in the right pleural cavity, and abdominal CT showed liver cirrhosis, splenomegaly, and portal hypertension with the possibility of abdominal varices.

Abnormal liver function.

Gu Yanan looked at the medical records, and finally his eyes fell on the lymph nodes.

Swollen lymph nodes are a very typical symptom of scrub typhus.

Looking at the files of other hospitalized villagers, they all have swollen lymph nodes.

Primary doctors generally take the patient's skin eschar as one of the diagnostic criteria for scrub typhus, if the patient does not have obvious eschar on the surface, they will generally rule out the possibility of scrub typhus as soon as possible, and scrub typhus is often sporadic, and this kind of collective disease is very rare.

If this is the case, it is likely to be missed.

In the evening, the county disease control personnel sent specimens from the hospitalized villagers.

The specimens were sent to the laboratory, and Gu Yanan greeted Section Chief Li of the Disease Control Laboratory, "Section Chief Li, this batch of specimens will first do a nucleic acid test for scrub typhus oriental body." ”

Section Chief Li asked, "Isn't it a food poisoning incident?" How do I get tested for scrub typhus? ”

"I've looked at the patient's medical record file and it feels more like scrub typhus."

"Okay, listen to the director of our emergency office, if the occupant typhus test is negative, then check other causes of food poisoning."

It was past the end of the evening work, and Gu Yanan was still waiting for the results of the overtime test in the laboratory in the emergency office.

Two hours later, Section Chief Li of the laboratory called Gu Yanan, "Director Gu, you are really a god, the patient's specimen is indeed positive for scrub typhus occidental nucleic acid, this is not a collective food poisoning incident, it is a collective outbreak of scrub typhus, it is very rare, it seems that your emergency team is busy again." ”

Hearing that the results of the experiment were the same as his own speculation, Gu Yanan frowned, scrub typhus can break out collectively, indicating that the carrying rate of scrub typhus in local wild animals is very high, which is not a good thing, human intervention is needed, otherwise it is the rice harvest season, and more people will be infected.

Gu Yanan immediately sent a message to the chief of Qingcheng County CDC, saying that on the second day, he would go to Lijia Village at the foot of Qingcheng Mountain to catch wild rats, and the local county CDC would assist them in carrying out publicity and education and rodent eradication actions for the villagers.

The two of them discussed the things to be prepared on the second day, rodenticide, rat trap cage, and rat sticking board......

Inventory the reserves of these materials, and allocate them in a timely manner if the quantity is insufficient.

After discussing with the county disease control and control, Gu Yanan sent a message in the QQ group of the emergency team, "Tomorrow, the emergency team will collectively set off to carry out rodent extermination operations near Lijia Village at the foot of Qingcheng Mountain, and set off collectively in the central compound at 7:30 in the morning, wearing wild protective equipment uniformly." ”

It's past the end of work, and at about 8 o'clock in the evening, the emergency team immediately exploded.

Wang smiled: "Wow, scrub typhus has been diagnosed, and I'm going to catch mice again." ”

Lu Li: "It's not bad to go to the wild to catch mice in this season, it's much stronger than going to the mountains against the northwest wind in winter, and now there are fruits on the mountains and the scenery is good, so it's a way to go out for an outing, this action, I like it." ”

Goofy: "We've chased wild boars and caught mice." ”

Zhou Lao: "Not only have we chased wild boars and rats, but we have also caught birds in the sky, dug in the ground, hunted in the mountains, caught fish in the river, drilled through karst caves, went down to the bottom of the sea, fought in groups, and worked undercover...... If you don't have any skills, you really can't do this business. ”

Xiao Chu: "I just entered this industry, many of them have not experienced it, is the disease control work really as exciting as you say?" ”

Zhou Lao: "It's exciting, and sometimes it's scary, and you'll know after a few more experiences." ”

Xiao Chu: "Looking forward to becoming a full-time employee of disease control and ...... first field experience"

Wang Xiaoxiao: "Yes, Xiao Chu is already an official member of our emergency team, I want to have a treat, let's discuss the place of dinner." ”

Lu Li: "Xiaoxiao, you know how to eat, didn't you just get together some time ago?" ”

Wang Xiaoxiao: "Lu Li, you didn't understand what I meant at first glance, our dinner is to connect with colleagues, like this kind of big event for new members to join, we must have a good get-together, the last time we had dinner was because Xiao Chu joined the emergency team as an intern, now it's different, he is a regular employee of our disease control, it's worth getting together again." ”

Lu Li: "Okay, you always have many reasons, but you don't need to find a place to have dinner, aren't you going to catch wild mice tomorrow?" We can catch the wild mice and barbecue directly in the field, and the roast wild mice under Qingcheng Mountain must be a very unforgettable dinner. ”

Gao Fei: "I'll go, Lu Li, you're too disgusting, you just eat wild mice, don't talk nonsense in the group, scare our new colleague Xiao Chu." ”

Wang Xiaoxiao: "Many of the wild mice we are going to catch this time carry scrub typhus oriental body, and you are not afraid of getting sick if you eat it." ”

Zhou Lao: "Wild mice not only carry scrub typhus, but also many other pathogens, such as plague, hantavirus in hemorrhagic fevers, and various parasites ......"

Xiao Chu: "It doesn't matter, it can be killed at high temperatures, but it must be baked, and it must be very cooked." ”

Wang Xiaoxiao: "......"

Lu Li: "......"

Goofy: "......"

Old Zhou: "Xiao Chu...... Sure enough, it's in our disease control business. ”

Gu Yanan: "Welcome Xiao Chu to officially join, just roast wild mice, invite you to eat roast sheep another day." ”

Wang smiled: "Yes, long live Sister Yanan!" ”

……

——

Day 2 morning.

Lijia Village at the foot of Qingcheng Mountain.

Six members of the municipal CDC emergency team and people from the local county CDC on-site department met outside Lijia Village.

Gu Yanan and Chief Pang discussed the action plan.

"Section Chief Pang, today we are going to collect some wild mouse books from the surrounding rice fields, as for the rat extermination is a long-term project, we need to mobilize the villagers, so I want to take the emergency team to put the rat trapping equipment in the rice field this morning, and go to the village to do propaganda in my free time at noon, you are more familiar with the villagers here, you can first take the county disease control people to the surrounding villages to do propaganda and mobilization, and at noon our emergency team will go to you, what do you think?"

"Okay, according to Director Gu's arrangement, we will act separately."

The group was divided into two groups, Chief Pang took the county CDC people to the surrounding villages, and Gu Yanan led the city's CDC emergency team to start placing equipment to catch wild mice in the rice fields around Lijia Village.

There are many sticky mouse boards in the instrument, because the sticky mouse board can catch live mice, although the mouse trap can also catch mice, but most of the mice caught each time are dead and injured, and the wounds are blurred flesh and blood, if the rats carry pathogens, they may also pollute the surrounding environment, so this time they are all sticky mouse boards and rat trap cages.

Gu Yanan and his entourage wore special protective clothing for field work, and the collar and cuffs were tightly tied to prevent chigger mites from burrowing into their bodies with the gaps.
