Dongcheng District, Lianhai City, Republic of China Road, the old house of Nanhanfei's family.

Gu Yanan parked the car outside the yard and called Nan Hanfei with a casserole of chicken soup.

Soon, Nan Hanfei ran into the courtyard wearing a pair of slippers and opened the courtyard gate.

Nan Hanfei's expression was surprised and delighted, "Yanan, I really didn't expect you to send me supper." ”

"Why are you upset? If you don't want it, then I'll take it back. ”

Gu Yanan pretended to turn around.

"Wait!" Nan Hanfei grabbed Gu Yanan's arm, "I'm so happy that you can come, come into the house." ”

The old house of Nan Hanfei's family is a typical building of the Republic of China, a two-story building, like Uncle Ge's house next door, with a square yard planted with some flowers and trees.

Passing through the courtyard, entering the door is the living room, inside the furniture is antique.

This is the first time Gu Yanan has come to Nan Hanfei's house, I have always known that the houses on this side of the Republic of China Road are historical preservation buildings, but I didn't expect that the furniture inside is also like the one handed down from the Republic of China, and it seems to have entered that era when I was in it.

Gu Yanan handed the chicken soup in his hand to Nan Hanfei, looked around, and sighed, "A very historical house, such a big house, are you the only one who lives alone?" ”

"Well, this is the house that my grandfather inherited from my great-grandfather, since he went to settle abroad, this place has been taken care of by relatives, after I came back two years ago, I took over living here, although I live alone, but usually there will be an aunt in charge of cleaning regularly to come and clean."

An old-fashioned wall clock hung on the wall of the living room, and it was already 9 p.m. when it rang crisply.

The late-night chicken soup was delivered, and Gu Yanan decided to leave.

"Don't go yet, accompany me to drink chicken soup, if you want to get fat, the two of you will be fat together."

Nan Hanfei found two bowls from the kitchen, opened the chicken soup in the casserole, and filled one bowl for each person.

Gu Yanan didn't shirk either, sitting at the dining table and watching Nan Hanfei take a sip before drinking it himself.

"How's it taste?"

"Delicious on earth." Nan Hanfei sighed, and then sighed, "It was worth sacrificing your life to save your life at the beginning!" ”

Gu Yanan chewed the words, "What sacrifice?" When the car accident occurred on the sea-crossing bridge, you happened to pass under the bridge, and you should have saved me just by the way. ”

Nan Hanfei smiled, "That time...... If you say it's by the way, that's by the way. ”

After drinking the chicken soup, Gu Yanan wanted to clean up the casserole and chopsticks, Nan Hanfei held her hand, "No, I'll clean it up later, and I'll send it to you when the casserole is washed." ”

Nan Hanfei looked for everything to increase the opportunities for the two to interact.

"Just finished drinking late-night chicken soup, do you want to lose weight?" Nan Hanfei asked.

"Lose weight? Do you want to go out for a walk? It's a bit late. Gu Yanan was a little hesitant, it was indeed late after drinking the chicken soup, she didn't want to give Nan Hanfei some kind of illusion as her mother said.

Nan Hanfei smiled very meaningfully, "I read your Moments tweet this afternoon, and the article on your CDC official account was also written by you, right?" ”

"Which one?"

"The one about kissing."

"The text was written by me, and the pictures were matched by Lu Li."

"Does kissing really lose weight?"

"Really, I listed the scientific basis in today's article."

"Do you want to lose weight now?" Nan Han smiled away, his face a little serious and serious.

Gu Yanan reacted immediately, blushing behind his ears and shaking his head, "I don't want to!" ”

Then, Gu Yanan blushed and fled from the old mansion of Nan Hanfei's family.

Early in the morning of the second day, Gu Yanan was downstairs in the bachelor apartment.

Nan Hanfei carried the washed casserole and waited there.

Gu Yanan, as usual, got up early to go for a run in the garden next to the community, and went downstairs to meet Nan Hanfei.

Nan Hanfei acted as if nothing had happened last night, and was about to talk to Gu Yanan.

Gu Yanan's mobile phone in his pocket rang.

Caller ID brother Gu Yoshiki.

"Little sister, recently our hospital has admitted a number of patients, all of whom have symptoms of peripheral neuritis, and the patients are concentrated in neighboring villages, I suspect that it is poisoning, but the specific poison has not been detected, your CDC will help to do physical and chemical testing."

"Mass poisoning? How many people are there? ”

"The cases in our hospital have all been transferred from the county hospital, and there are 12 patients who have been transferred, all of whom are from Lijia Village, Guanyun Township, and several nearby villages. According to the Guanyun Township People's Hospital, the hospital also admitted more than 40 patients, so there should be more than 60 patients. ”

"More than 60 people? This is a very big epidemic, okay, I'll bring someone over to deal with it right away. ”

Ending the call with his brother Gu Jiashu, Gu Yanan said to Nan Hanfei beside him, "There is an epidemic, I have to go to the hospital now, what are you looking for me?" ”

"It's okay, I'm just here to return your casserole, and I want to ask you to have breakfast together, since you have something, then another day, do you need my help today?"

"Not at this time."

The First People's Hospital of Lianhai City, outside the neurology ward.

As a member of the CDC emergency team, Gu Yanan first came to the hospital to check on the situation.

In the corridor outside the neurology ward, several doctors from the hospital had just finished a specialist consultation when they saw the disease control people coming and gathered in the corridor outside the ward.

Because of her work, Gu Yanan is a frequent visitor to the People's Hospital and is familiar with many doctors.

Gu Jiashu, director of the Department of Infectious Diseases, and Zhang Jianzhong, director of the Department of Neurology, are among them.

The patients who were transferred to the hospital were temporarily placed in the neurology department because they all had peripheral neuritis symptoms.

Gu Yanan asked Zhang Jianzhong, director of the Department of Neurology, "How is the situation now?" ”

"Among the 12 patients transferred to the hospital, the youngest is 5 years old, the oldest is 81 years old, and the disease is concentrated in the family unit, the clinical symptoms of the patient are symmetrical sensory, motor, and nutritional disorders in the limbs, and the distal end is heavier than the proximal end, and the motor nerve damage of the lower limbs in the early stage of the disease is manifested as toe numbness, calf coldness, muscle swelling and pain, and the patient claims to have gloves and socks.

The severity of each patient varies, and the mild symptoms are weakness in walking, unsteady standing, and a broad gait; Severe limb paralysis, bedridden, unable to take care of himself. ”

"I have to look at the medical records of all the patients who have been transferred to the hospital."

"The case file is in the neurologist's office, come with me."

Neurologist's office.

Zhang Jianzhong and Gu Jiashu accompanied Gu Yanan to look through the patient's medical records.

The medical records record the process of treatment for the patients at the county people's hospital in detail, and there is no obvious effect on the treatment of arsenic poisoning, radiculitis, and viral diseases.

After being transferred to the First People's Hospital of Lianhai City, several heavy metal poisons were tested, such as lead, mercury, and chromium...... The tests were all negative.

The most important thing in the treatment of poisoning is to find the cause of the poisoning.

Gu Yanan: "Collect the blood, urine, and hair of all the patients, and I will take them back to the CDC laboratory for poison screening." ”

Gu Yanan also wrote down the home address in the patient's medical record, and then conducted an on-site investigation of the patient's living environment.
