Lianhai Center for Disease Control and Prevention, Emergency Office.

Wang Xiaoxiao has completed the task assigned by Gu Yanan and searched for the medical records of all hospitals above the second grade in Lianhai City.

From these records, patients with symptoms similar to sleeping sickness but no confirmed cause were identified.

There are a total of 26 such cases, 20 of which are located near the flower and bird market in the western suburbs of Lianhai City.

This caught Gu Yanan's attention.

It is no coincidence that patients are concentrated in a certain area.

Gu Yanan's gaze stopped at the information of one of the patients.

Ge Changjiang, 62 years old, home address: No. 82, Minguo Road Street, the western suburbs of Lianhai City.

Isn't this the address of Uncle Ge, Nan Hanfei's neighbor?

Thinking of his previous experience at Uncle Ge's house and the police station, Uncle Ge has already shown symptoms of lethargy, which is already a late symptom of sleeping sickness.

Gu Yanan was busy assigning tasks to everyone in the emergency office.

Wang Xiaoxiao was responsible for contacting the staff of the district CDC to conduct follow-up sampling of these 26 patients, and after further collecting specimens, they were brought back to the CDC laboratory for diagnosis of the etiology of sleeping sickness.

Lu Li first stayed in the CDC laboratory to test the samples of the flower shop owner collected from the flower and bird market this morning.

Gu Yanan went to the courtyard of Uncle Ge's house on the Republic of China Road.

——

Outside the door of Uncle Ge's courtyard.

Gu Yanan stood at the door with a sampling box and knocked on the door, but no one responded.

The door was locked from the inside, but no one came out to open the door, could it be that something happened to Uncle Ge at home?

Gu Yanan was in a hurry, and he couldn't break in.

After hesitating, Gu Yanan thought of Nan Hanfei, she still had Nan Hanfei's number in her mobile phone, Nan Hanfei was Uncle Ge's neighbor, he must have a way.

After making a phone call, Nan Hanfei quickly appeared in front of Gu Yanan.

"Uncle Ge's door can't be opened, it's locked inside, he must have had an accident, can you open the door?"

Before Gu Yanan's words fell, Nan Hanfei had already kicked open the door of Uncle Ge's courtyard.

Across the courtyard, the two rushed into Uncle Ge's room.

Uncle Ge was lying on his bed, very quiet, as if he was asleep.

Nan Hanfei approached the bed and called softly, "Uncle Ge? ”

Uncle Ge didn't react.

Gu Yanan stepped forward to test Uncle Ge's pulse and eye reaction, "He is in a coma and must be sent to the hospital as soon as possible." ”

Nan Hanfei carried Uncle Ge out of the small courtyard, put him in his car, and sent him to the Infectious Diseases Department of the First People's Hospital of Lianhai City with Gu Yanan.

Gu Yanan was very familiar with the doctors in the infectious disease department, and told Uncle Ge about his usual situation, and suggested that they treat it directly according to Trypanosomiasis.

The hospital took blood samples from Uncle Ge, and the samples were divided into two parts, one was prepared for blood smear examination in the hospital laboratory department to see if the causative agent of West African trypanosomiasis could be detected, and the other was prepared to be brought back to the CDC laboratory by Gu Yanan for PCR testing.

Uncle Ge has no relatives by his side, Nan Hanfei is his neighbor, and he usually has a good relationship, so Nan Hanfei decided to stay in the hospital to take care of Uncle Ge.

Gu Yanan was holding Uncle Ge's specimen and was about to go back to the CDC, when he suddenly remembered that Nan Hanfei had said before that he also had symptoms of fever and fatigue like to sleep.

Gu Yanan stopped, returned to Uncle Ge's bedside, looked at Nan Hanfei who was taking care of Uncle Ge at the bedside, Gu Yanan stretched out his hand and touched the back of Nan Hanfei's neck.

Nan Hanfei subconsciously leaned back, and at the same time asked in surprise, "What are you going to do?" ”

Gu Yanan withdrew his hand, realizing that his action just now was a little abrupt, and hurriedly explained: "I just wanted to check it on you, I suspect that you are also infected with Trypanosomiasis." ”

"How do you want to check?"

Nan Hanfei approached Gu Yanan and made a gesture of cooperation.

Gu Yanan stretched out his hand and touched the back of Nan Hanfei's neck.

Swollen lymph nodes in the posterior cervical triangle.

Gu Yanan's heart sank, which is typical of trypanosomiasis.

Gu Yanan did not do too much physical examination on Nan Hanfei, but directly asked Nan Hanfei to stretch out his arm to collect blood.

Nan Hanfei was very cooperative, and after seeing Gu Yanan's blood collection, Nan Hanfei asked, "Can it be diagnosed?" ”

"The symptoms are consistent with the signs of West African worm disease, but further laboratory tests are needed to confirm the diagnosis, and this tube of blood is used to confirm the diagnosis."

Nan Hanfei had always felt that his body was a little uncomfortable before, but because he usually did physical exercise and had a good physical foundation, he didn't pay attention to some small problems.

Nan Hanfei saw Gu Yanan packing the sampling box and preparing to leave, and asked, "What should I do now?" ”

"Stay in the hospital and wait for the test results, and when the test results come back, you will be scheduled for treatment."

Nan Hanfei didn't speak, and he acquiesced to Gu Yanan's arrangement.

Gu Yanan temporarily answered a phone call, which was from Lu Li's CDC laboratory.

It has been confirmed that the owner of the flower shop in the western suburbs has a positive PCR test for West African trypanosomiasis.

Gu Yanan felt that the situation was not good, the owner of the flower shop in the flower and bird market had never been to Africa, and Chen Dali had never been to Africa, so the source of the infection might be somewhere in Lianhai City.

A potential source of infection, if not detected in time, will infect many more people.

Every time Gu Yanan thought about a problem, his face was very serious, and this time he was about to walk out of Uncle Ge's ward with the sampling box while thinking about things, when he suddenly remembered something, and turned around and asked Nan Hanfei, "Do you have any relatives in Lianhai City?" ”

Nan Hanfei shook his head, "My parents are abroad, I am the only one working in China, I have worked in Lianhai City for two years, I usually live alone, although I have no relatives, but I still have friends." ”

Nan Hanfei replied, as if Gu Yanan was inquiring about the household registration, and Nan Hanfei answered in great detail, as if he wanted to let Gu Yanan know more about himself.

"Oh, I'm worried that if you're hospitalized, no one will take care of you, so I'll come to the hospital when I'm done with CDC."

After Gu Yanan finished speaking, without waiting for Nan Hanfei to react, he left the ward with the sampling box.

Nan Hanfei reacted after realizing that Gu Yanan was promising that she would come to the hospital to take care of him just now.

Nan Hanfei's heart was filled with warmth.

Lianhai Center for Disease Control and Prevention, Laboratory.

Specimens from 26 patients were sent to the CDC laboratory.

Lu Li and Gu Yanan were busy in the laboratory, and three hours later, the results of the experiment came out.

Among the 26 patients, 22 of the patients' specimens had positive PCR results, among which the blood samples of Uncle Ge and Nan Hanfei were also positive for West African trypanosomiasis.

Gu Yanan informed the hospital of the results of the experiment in time, and the hospital arranged for the patient to be hospitalized and began to treat the pathogen.

Nan Hanfei was also hospitalized.

After processing the test results from the CDC laboratory, Gu Yanan issued an epidemic notice online and rushed to the hospital.

On the one hand, it is to visit Nan Hanfei, who has just been hospitalized, and on the other hand, the most important thing is to ask for clues about this West African trypanosomiasis.
