In the compound of the Municipal Center for Disease Control and Prevention, the lights in the two mobile testing vehicles were brightly lit, and Nan Zhiqiao and Ye Zhenzhen changed into new protective clothing and entered the testing vehicles.

In the inspection car, there were already two figures busy, and when they saw Nan Zhiqiao and Ye Zhenzhen getting into the car, they all greeted each other, "Director Nan, Teacher Ye." ”

Nan Zhiqiao asked, "What step has you done with the specimens sent?"

"I did a smear stain, and the result was gram-negative Vibrio, and the multi-pathogen PCR screening for diarrhea was also on the machine, and the results came out two hours later. ”

"Is the hanging drop test done?"

"Not yet. ”

"Okay, bring me the specimen from the diarrhea patient to be examined. ”

Nan Zhiqiao went to the dark-field microscope, and someone immediately put a row of test tube racks on the table next to Nan Zhiqiao.

Most of the patient specimens are feces, vomit, and blood, and Nan Zhiqiao uses a small straw to absorb fresh fecal specimens, drip them on a clean slide, and put them under a dark-field microscope.

Nan Zhiqiao asked again, "Is there a list of descriptions of the patient's clinical symptoms sent with the specimens?"

"Yes, here. ”

Someone handed a stack of white paper sheets to Nan Zhiqiao, and Ye Zhenzhen also came up to her, looking at the contents of one of the lists.

Patient's name, Wang Yi, clinical symptoms: sudden diarrhea, followed by projectile vomiting, no obvious abdominal pain, no tenesmus, frequent and large stools, at first yellow watery stools, soon turned to rice swill. Projectile vomiting, initially stomach contents, followed by watery and rice swill. Patients present with circulatory collapse symptoms such as decreased blood pressure, weak pulse, increased hemoglobin and plasma specific gravity, and decreased urine output.

Looking at the content on the next list, it is probably the same, and there are other symptoms, such as systemic electrolyte imbalances and muscle cramps.

Open the next one, and among the similar symptoms, there is more hypokalemia syndrome, generalized hypotonia, loss of tendon reflexes, intestinal tympanic, tachycardia, and arrhythmia.

After a rough review of each list, each patient had similar symptoms, diarrhea, vomiting, massive loss of fluids and electrolytes, circulatory collapse, and electrolyte imbalances.

Nan Zhiqiao put down the list in his hand and said to the person in charge of the Municipal Disease Control and Inspection Department who was present, "Now it is highly suspected that it is an infectious disease caused by Vibrio cholerae, notify the clinician, first follow the cholera treatment plan, and after two hours, the laboratory diagnosis results will come out. ”

The person in charge of the laboratory department of the Municipal Center for Disease Control and Prevention is a middle-aged man in his forties, who listened to Nan Zhiqiao's arrangement, and nodded busily in agreement, "I'll go and notify the hospital and the on-site department of the CDC." ”

"Wait a minute!"

The person in charge was just about to leave, but was stopped by Nan Zhiqiao again.

Nan Zhiqiao also instructed: "Directly report to the municipal health emergency administrative department, control the epidemic requires the coordination and cooperation of various departments, they have this responsibility and right, and also, to notify the relevant personnel, for the cholera epidemic point, in accordance with the principle of 'early time, small scope, strict measures, and implementation', strive to solve the epidemic problem in the shortest possible time, for the cholera prevention and control of the entire disaster area, it is best to transfer cholera vaccine from nearby provinces and cities to carry out emergency vaccination for the masses." ”

"Okay, I know. ”

The person in charge trotted out of the mobile inspection vehicle, leaving only a few inspectors in the car.

Although Ye Zhenzhen was very tired, she was more worried about this cholera epidemic, and while waiting for the results of the experiment, she came to Nan Zhiqiao's side and asked, "Senior Nan, will this cholera epidemic be very serious?"

"At present, within the controllable range, as long as it is done in accordance with the requirements of prevention and control, it can be controlled in a short time. ”

Ye Zhenzhen was comforted by Nan Zhiqiao's words just now, and unconsciously breathed a sigh of relief.

Nan Zhiqiao asked rhetorically, "What? Are you worried about this epidemic?"

"Well, in the past, when there was a cholera pandemic, millions of people died, and now the city is in a sensitive period after the earthquake, and various conditions provide a breeding ground for cholera epidemics. ”

"Since records began, there have been seven cholera pandemics in the world, the first of which was introduced to our country and all subsequent pandemics that have affected our country. With the development of social economy, the improvement of people's living standards and the improvement of health and medical services, in the past ten years, the cholera epidemic in China has been basically controlled at a low level, cholera is an intestinal infectious disease infected through the fecal-oral route, mainly through water, food and close contact with life, as long as the transmission route is cut off, the source of infection can be controlled. ”

Nan Zhiqiao explained, Ye Zhenzhen understood it, but she was still a little vague about the policy slogan in Nan Zhiqiao's mouth just now, "Senior Nan, what is that 'three pipes, one annihilation, one propaganda'?"

"Management of food, water, manure, fly control, health education. In fact, this slogan means to cut off the transmission route of cholera. ”

Ye Zhenzhen sighed: "Senior Nan, you remember these policy slogans very clearly. ”

"Those slogan slogans are a summary of the usual disease control work, which is easy to remember, and you will not forget it as long as you read it once. ”

Zhen Zhen sighed in her heart, she is really a great god, and she feels that everything is easy to remember, but I am not sensitive to these slogan things, unless it is often brainwashed to remember, it seems that memory sometimes has to talk about methods.

Thinking of remembering things, Ye Zhenzhen began to feel sleepy, and couldn't help but sigh.

Nan Zhiqiao raised his wrist and looked at the time on his watch, it was already eleven fifty-five in the evening, and it would be the early morning of the next day in five minutes.

"Zhenzhen, you go back and rest first. ”

"Senior Nan, what about you?"

"I'll go back when the PCR results come back. ”

"I'll wait with you. ”

Ye Zhenzhen didn't want to leave alone first, so she endured sleepiness and stayed by Nan Zhiqiao's side.

Nan Zhiqiao wanted to persuade again, but looking at Ye Haohao's shining eyes, he swallowed back the words that came to his mouth, "Okay, then come and help, sort out these specimens, and then go online to the cholera database of the PulseNet China Central Laboratory to download a few pieces of data for backup." ”

"Oh, okay. ”

The two were busy working overtime in the emergency testing vehicle to conduct experiments, and after one o'clock in the morning, the PCR results came out, and it was determined that the pathogen causing the diarrhea epidemic was Vibrio cholerae.

Just after finishing this batch, a new batch of patient specimens was sent by the local hospital, and the patients all had the same symptoms of diarrhea and vomiting.

Just halfway through the process, someone knocked on the door of the emergency inspection vehicle.

Ye Zhenzhen thought to herself, could there be new cases? Could the cholera epidemic spread so quickly?

The car door was opened, and two familiar figures stood in the doorway.

"Fang Nana, Gao Wei, why are you two here?"
