Standing outside the door of the car were Fang Nana from the Infectious Disease Institute and Gao Wei from the Radiation Institute.

Ye Zhenzhen exclaimed, on the night after the earthquake, everyone felt a little warm when they saw familiar colleagues and friends.

Fang Nana pointed to herself and Gao Wei beside her, and spoke first, "The two of us came with the third batch of rescue teams in the center, we just arrived half an hour ago, and after inquiring, we knew that you were here, so we came here first." ”

Gao Wei also explained to himself, "There is a nuclear power plant near the city, and this earthquake has also affected the nuclear power plant, so we came to take a look." ”

"Nuclear power plant?" Ye Zhenzhen went through the map of the nuclear power plant in her mind, and couldn't remember what nuclear power plants were nearby, Zhen Zhen asked: "Is there a nuclear power plant near the city?"

"Yes, but it is still under construction and has not been officially put into use, so there is no radioactive danger, and our radiation station sent someone this time to check the extent of the damage to the nuclear power plant due to the earthquake. ”

"Oh, I see, then you should go to the nuclear power plant, why did you come here with Fang Nana?"

Gao Wei glanced at Fang Nana, her face was a little shy and shy, and explained: "It's too late and it's dark, I'll accompany her over, since the person has been delivered, then you are busy, I still have something to discuss with the people from the Municipal Disease Control and Radiology Department." ”

Gao Wei trotted away, Ye Zhenzhen looked at Fang Nana, and the back of Gao Wei leaving, as if she had an understanding.

Fang Nana also looked a little embarrassed, and hurriedly changed the topic, "Zhenzhen, you've all been busy all day, I'll help." ”

"Great, I'm worried about the lack of manpower. ”

Fang Nana changed into protective clothing, got into the emergency inspection vehicle, and greeted Nan Zhiqiao respectfully when she saw her.

Nan Zhiqiao answered, looked at Fang Nana, and asked, "Are you familiar with the laboratory testing operation of Vibrio cholerae?"

Fang Nana nodded seriously, "Well, our experimental group often does cholera testing. ”

"Can all operations be done independently?" Nan Zhiqiao asked again.

"Yes, it can be done independently, and it is very skilled. "Fang Nana is quite confident.

"Okay, you take over, here is a batch of new patient specimens, the nucleic acid has been raised, and after the system is ready, you can go directly to the PCR machine. Nan Zhiqiao began to explain the task.

"Ah, am I alone?" Fang Nana asked in surprise, originally thinking of chatting with her friend Zhen Zhen, who she hadn't seen for a long time, but now in this situation, not only can she not chat, but she also has to work overtime here alone.

"It's not alone, in two minutes, there will be a local CDC inspector coming. ”

"Oh, okay. ”

Fang Nana began the handover work in earnest.

After the handover of the work, the inspectors from the local CDC also happened to rush over, working in pairs and officially changing shifts.

Nan Zhiqiao and Ye Zhenzhen, because they were tired from running around for days, their eyes were bloodshot, the two came out of the emergency detection vehicle, looked at each other, and smiled at the same time: "Hard work." ”

Nan Zhiqiao: "Zhen Zhen, go back and get a good night's sleep, there are still many things to be busy tomorrow." ”

"Senior Nan...... Good night!"

Ye Zhenzhen originally had a stomach full of words to say to Nan Zhiqiao, but when she thought that there were more than a dozen black-clothed people secretly following Nan Zhiqiao, what she wanted to say finally became a "good night".

——

The next morning, the rain finally stopped, and the sun rose and began to bake the earth.

Ye Zhenzhen was woken up by the noisy footsteps outside the simple tent, and when she looked at the time, it was almost eight o'clock in the morning, so she hurriedly got up from the bed, rinsed her mouth, brushed her teeth and washed her face, and got everything done in five minutes, and hurriedly ran to the catering point, took breakfast, and went to find Nan Zhiqiao.

Nan Zhiqiao was packing up his things, and Ye Zhenzhen stepped forward, "Senior Nan, where are you going?"

"First go to the First People's Hospital of the city, look at the patient's situation, do an epidemiological investigation, and find out the root cause of the cholera epidemic. ”

"I'm going too, when will I go?"

Nan Zhiqiao glanced at the breakfast in Ye Zhenzhen's hand and said, "Finish the breakfast first, and gather at the emergency inspection vehicle at eight twenty." ”

Outside the emergency testing vehicle, Ye Zhenzhen said hello to Fang Nana, who had just come down from the shift, and followed Nan Zhiqiao to the First People's Hospital not far from the city's disease control and control with disinfection drugs and equipment.

In the city's First People's Hospital, the two went to the cholera isolation ward, looked at the patient's clinical symptoms, asked the patient's contact history, asked around, the two summarized the situation, and finally locked the target of the suspected source of infection on the water source.

But how can cholera spread when the water in the urban settlements is disinfected?

Nan Zhiqiao and Ye Zhenzhen were standing outside the isolation tent of the hospital, discussing the next treatment of the cholera epidemic, when suddenly, a familiar boy ran over and greeted the two, "Teacher Nan, Teacher Ye, you are also here?"

The boy who ran over was Zhu Wu, a high school student, and when Zhu Wu saw the benefactor who saved his entire village, he hurriedly ran forward to say hello, with a grateful smile on his face.

Ye Zhenzhen asked rhetorically, "Zhu Wu, why are you here?"

Zhu Wu pointed to another medical tent not far away, "My dad's leg was cut by a tree branch and he was hospitalized over there. ”

Ye Zhenzhen remembered that in the earthquake that collapsed last night, there was a villager who was trapped by a big tree, and at that time, she and Senior Nan rescued people from under the tree, and it seemed that the injured villager was Zhu Wu's father.

"How is your father's injury, do you want us to help?" Ye Zhenzhen asked with concern.

"Yesterday, I saw my dad's leg injury, the flesh was blurry, and I thought it was very serious, but after treatment, the doctor said that it was just a flesh injury, not a bone, and it would be fine for a month or two. ”

"That's good. Ye Zhenzhen breathed a sigh of relief in her heart, in the face of countless casualties, hearing this was already good news in bad news.

"But, this is the isolation ward, you don't take care of your dad in the ordinary ward, what are you doing here?"

"My second aunt had diarrhea and was sent here for treatment, and I wanted to come and see him. ”

Zhu Wu stretched his neck and looked into the isolation ward, Ye Zhenzhen stopped in front, "The isolation ward is full of infectious disease patients, you are not wearing protective clothing, you can't go in, don't worry, the patients inside are taken care of by doctors and nurses, it's okay." ”

Zhu Wu took two steps back and nodded cooperatively, "I just came to see, I didn't have to go in, oh, by the way, I just heard you say that you were looking for the source of the cholera epidemic, did you find it?"

Ye Zhenzhen shook her head with some disappointment, "Not yet, I'm looking for it." ”

Zhu Wu stepped forward very enthusiastically, "What can I help, although I am told to do it, although my hometown is in the remote Zhujiazhuang and I am in high school in Xiuli County, but every winter and summer vacation, I will come to the second aunt's house in the urban area, and I know the surrounding environment very well." ”

Nan Zhiqiao looked Zhu Wu up and down, as if thinking of something, and suddenly asked: "Zhu Wu, do you know the water supply in the urban area, in addition to the original Rose River, there are any other reservoirs or rivers?"

"Yes!"
