Nan Hanfei turned around and explained to the policeman Xiao Li what happened next, and asked them to go back to the police station first, while he stayed.

Gu Qingcen handed over the sampling box in his hand to Lu Li, and planned to stay.

Gu Yanan: "I'll take care of Xiaoxiao here alone." ”

Gu Qingcen rubbed his arm, "I was injured a little just now, I want to go to the hospital to see and get some medicine by the way." ”

Gu Yanan lifted Gu Qingcen's sleeve and found that there was a dark red bruise on his arm, which was injured during the group fight just now, and it was quite serious.

"So serious? I need to go to the hospital to see and get some medicine, okay, let's take Captain Nan's car to the hospital in a while, and the others will go back quickly. ”

Lu Li, Zhou Jie, and Gao Fei drove the on-site flow shunting of the CDC back to the CDC laboratory, leaving Gu Yanan, Nan Hanfei and Gu Qingcen ready to send Wang Xiaoxiao to the hospital.

Soon, Wang Xiaoxiao came out of the hotel bathroom, covered her stomach, with a painful look on her face, and said to Gu Yanan, "Sister Yanan, I think I also have food poisoning, what I pulled out just now was water-like poop, and I was chilled, I should have a fever." ”

Gu Yanan reached out to wipe Wang Xiaoxiao's forehead, it was hot!

Sure enough, I had a fever.

"Go to the hospital!"

——

Lianhai First People's Hospital, Department of Infectious Diseases.

Wang Xiaoxiao was admitted to the infectious disease department because of food poisoning symptoms.

Gu Qingcen was taken by Gu Jiashu to the next clinic to deal with the bruises on his arm.

Gu Yanan took care of Wang Xiaoxiao while investigating the cause of her food poisoning.

Wang Xiaoxiao had a hanging needle on her arm to replenish body fluids, and said to Gu Yanan, who was guarding the bedside, "Sister Yanan, do you think I am considered a work injury?" I participated in an investigation for food poisoning and I developed symptoms of food poisoning myself. ”

"That's not how you get a work injury, and judging by the rate at which bacterial or viral food poisoning occurs, I suspect there's something wrong with what you eat at noon."

"Don't we all eat the same thing at lunch?"

Gu Yanan recalled the situation at noon, and suddenly, Gu Qingcen walked into the ward, he had already finished treating his bruises, heard the conversation between the two, and said, "You have eaten more than us, vegetable salad, although the amount is not much, if it contains pathogenic bacteria, it is enough to cause your current symptoms." ”

Wang smiled: "It can't really be a problem with vegetable salad, right?" At lunch, Gu Dashen was still talking about the food poisoning epidemic caused by German fenugreek bean seedlings, and as a result, I got food poisoning from eating vegetable salad? That's a coincidence! ”

While Wang Xiaoxiao complained, Gu Yanan had already picked up his mobile phone and dialed Lu Li's phone, "Lu Li, is there any leftover vegetable salad that Wang Xiaoxiao ate in the meal you packed at noon?" ”

"Yes."

"Let the lab test the food poisoning specimen with this one."

"Okay."

Hanging up the phone, Gu Jiashu hurriedly walked into the ward and said to Gu Yanan, "Little sister, just now the hospital has admitted a lot of patients with similar food poisoning symptoms, and I just asked them about the situation, which is different from the experience of the tour group and Wang Xiaoxiao, but they have all eaten in some restaurants, and the dining place is not fixed. ”

The epidemic has spread, and Gu Yanan feels that the situation is serious.

Leaving Wang Xiaoxiao to be taken care of by the doctor, Gu Yanan and Gu Qingcen began to conduct basic flow of newly admitted patients.

Soon, the information on the new cases was completely collated, and Gu Yanan found that there were a total of 5 restaurants where all the patients had been to, all of which were gathered in Dongcheng District.

In addition, the patients have eaten uncooked dishes such as cold dishes or vegetable salads from restaurants.

Gu Yanan got these clues and immediately ordered the rest of the emergency team to go to several restaurants in Dongcheng District that were involved in food poisoning to conduct sampling, especially to trace the origin of the raw food dishes that were served on the table.

While Gu Yanan arranged tasks for the disease control and emergency response team, Nan Hanfei was not idle, he was walking around the various wards of the infection department, looking at the patient's condition and asking the doctor's information, and after Gu Yanan finished calling, Nan Hanfei came to her, "I think the first case of food poisoning this time is not a tour group, it may be an old couple." ”

"Why? What clues did you find? ”

Nan Hanfei handed Gu Yanan the medical record file he asked for from the doctor in his hand, "There is an old couple in that ward, who were just transferred to the hospital this evening, and I found that Old Man Qiu's onset time was the earliest, and the initial symptoms were similar to those of this food poisoning patient, but he now has serious complications, thrombotic thrombocytopenic purpura, and mental symptoms, so you may have ignored it when you were in the flow just now." ”

Gu Yanan listened to Nan Hanfei's explanation while quickly looking through the medical records of Old Man Qiu and his wife, and found that Old Man Qiu first started to get sick, and the symptoms at the time of the onset were very similar to the symptoms of this food poisoning patient, and then there were mental symptoms such as delirium, and now there are severe thrombotic thrombocytopenic purpura complication symptoms, just looking at the current symptoms, it is indeed easy to ignore.

Mrs. Qiu's onset was later than that of Mrs. Qiu, and her symptoms were mild, just fever and mild diarrhea, and there were no complications.

Old man Qiu was indeed the first case of this food poisoning incident.

Conducting a flow investigation on Old Man Qiu should be able to get more clues.

Gu Yanan, Gu Qingcen, and Nan Hanfei entered Old Man Qiu's ward.

Old Man Qiu was confused and couldn't answer questions, but Mrs. Qiu was very talkative.

Mrs. Qiu said the whole thing, "My wife and I run a small farm in the suburbs, grow some fruits and vegetables, raise some chickens, ducks and fish, usually sell these agricultural products for a living, yesterday my wife suddenly had a fever, diarrhea, at first I thought it was a cold, I took some cold medicine and did not see good, that night he was weird, day and night reversed, and began to pull blood, I sent him to our local community hospital, the doctor said that it was gastroenteritis directly hung antibiotics, but it was not good, the symptoms are getting worse and worse, To make matters worse, I also started to have a fever and diarrhea, and I felt that something was wrong, so I asked to be transferred to the largest hospital in Lianhai City, and the doctors here should know what kind of illness our husband and wife had. ”

Gu Yanan asked Mrs. Qiu, "Have you ever been to a restaurant outside to eat before the onset of the disease?" ”

"No, we never go out to eat, we all eat what we produce on our farm, fruits, vegetables, fish, meat, eggs and milk, we have them all on our small farm."

Having never eaten anything outside, only eating what was produced on his own farm, Gu Yanan locked the suspected source of infection in the small farm.

Gu Yanan: "Has anything special happened on the farm recently?" For example, newly introduced animals or plants. ”

"Oh, I remember, I just bought a little yellow cow from the live stock market in the countryside a few days ago."

With the clue of the small farm of the first case, it was necessary to do on-site investigation as soon as possible, but the members of the emergency team were arranged to go to the major restaurants in Dongcheng District where food poisoning people appeared, and Gu Yanan decided to go to the small farm in person.

After settling down Wang Xiaoxiao, it was already dark, the on-site flow shunting car of the CDC was still in Dongcheng District, and the Dongjiao farm was located in the middle of nowhere, Gu Yanan wanted to go there to do the flow survey, so he could only go back to drive his own car.

Nan Hanfei knew Gu Yanan's plans and suggested, "I can send you to a small farm." ”

"I'll go too."

Gu Qingcen and Nan Hanfei, standing beside Gu Yanan on the left and on the right, were ready to go to the small farm together.
