Gu Yanan couldn't hold back his laughter, but when he thought about it, he was a little sad, and the smile on his face faded, "When I have time in the future, I will also come to help take care of Uncle Ge." ”

"I know you're a kind girl." Nan Hanfei whispered praise.

Gu Yanan was stunned, she didn't expect Nan Hanfei to praise her so bluntly.

Nan Hanfei wanted to help Uncle Ge put the bird cage back in the glass flower room, but Uncle Ge refused: "I'll come by myself, Xiao Nan, you accompany Miss Yanan." ”

Uncle Ge carried the bird cage to the glass flower room, walked halfway, and turned back to the two and smiled: "Nan Hanhan, Gu Yanan, you all have a Nan character in your name, this is also fate." ”

Uncle Ge took two steps forward, remembered something, and turned back again, "I almost forgot, I asked Miss Yanan to visit my glass flower room just now, come here, let's go together." ”

Nan Hanfei yawned inadvertently.

Gu Yanan noticed and thought to herself, Nan Hanfei is a criminal policeman, he is usually busy with work, and now he has helped Uncle Ge find the lost red-billed firefinch, he must be tired, it is better to let Nan Hanfei go back to rest early, so he refused: "Uncle Ge, I still have something to do, let's visit another day." ”

Uncle Ge remembered the flowers and birds in his glass flower room, and he didn't leave any guests, so he waved his hand and let the two leave.

After leaving Uncle Ge's courtyard, Nan Hanfei wanted to send Gu Yanan home, but Gu Yanan insisted on taking the subway by himself.

Nan Hanfei: "I said I was going to send you home, why did you regret it?" ”

Gu Yanan originally wanted to find another reason, such as the convenience of taking the subway, or what he was going to do halfway, but in the end he still said the real reason why he didn't let him send it, "You yawned a few times just now, I'm worried about your physical condition, so I think it's safer to take the subway, you should go back and rest more." ”

"Do you mean I don't have the strength to send a girl home right now? It's the most egestically depressing thing I've ever heard. ”

"I'm sorry, I didn't mean that, but in addition to yawning, you still have bloodshot eyes, and when I gave you a fruit basket just now, I touched your arm and found that your body temperature was higher than normal, indicating that you have a low-grade fever, which is a sign that your body is in sub-health."

"You're saying I'm sick?"

"Well, I hope you can go to the hospital after work."

Nan Hanfei shook his head with a wry smile, "Okay, your reason convinced me, I think it's just that I'm a little tired from working overtime these days, it's not a big deal, but for your personal safety, it's better for me to send you to the subway entrance." ”

——

The next morning, Gu Yanan went from his bachelor apartment to the CDC office.

As soon as I sat down in the office, put down my bag, and turned on the computer, the office phone on the desk rang.

The voice of my brother Gu Jiashu came from the phone, "Yanan, our hospital has admitted a patient suspected of sleeping sickness, and the hospital laboratory department has made a blood picture, and no trypanosomes have been found in the blood, and I want to send the patient's specimen to your CDC." ”

"Sleeping sickness?! Trypanosomiasis! ”

"Well, with the conditions of our hospital, it can't be diagnosed yet, so send the specimen to your CDC, I remember that Chagas disease is a disease monitored by the CDC, and your laboratory should have the corresponding reserve testing technology, right?"

"There are PCR test reagents, send the specimens, and the results will be available in three hours."

The patient's blood sample was quickly sent to the CDC lab, and the results came back three hours later.

PCR result is positive.

The patient admitted to the hospital was indeed suffering from trypanosomiasis.

While the results are fed back to the hospital, the CDC will conduct an epidemiological investigation of the case.

Trypanosomiasis is a zoonotic disease, and every time such a case is confirmed, the hospital must report the epidemic system and the CDC will conduct an investigation of the disease.

Gu Yanan attaches great importance to the discovery of West African trypanosomiasis in the hospital, because this is the first time that such a patient has been found in Lianhai City.

Trypanosomiasis, as the name suggests, is a parasitic disease found in Africa, and it is only endemic in African countries, and the cases found in China are all returned from traveling from Africa, which is an imported case, although the patient is also the source of infection, but because of the lack of an important transmission chain in the middle - tsetse flies, the possibility of secondary transmission in China is relatively small, and the epidemiological investigation is also easy.

Gu Yanan took the questionnaire and prepared to go to the First People's Hospital of Lianhai City to conduct an epidemiological investigation of the patient and its surroundings.

Without waiting for Gu Yanan to walk out of the office door, Lu Li followed behind Gu Yanan and begged: "Director Gu, take me to the hospital with you, sleeping sickness is too rare, I have only seen it in textbooks, let me open my eyes too." ”

Gu Yanan deliberately said: "I'm going to do business, epidemiological investigation. ”

Lu Li hurriedly changed his words, "I said the wrong thing just now, not to open my eyes, but to study with Director Gu, and by the way, to help Director Gu conduct an epidemiological investigation, and ask Director Gu to give me a chance to learn." ”

Lu Li has just joined the emergency office of the CDC for a year, and although he is usually a little flamboyant, he is indeed diligent and inquisitive.

Gu Yanan asked: "Since you want to go to the field to do epidemiological investigations, how much do you know about West African trypanosomiasis?" ”

Lu Li graduated with a master's degree in public health, and the knowledge in this book is difficult for him, "West African trypanosomiasis, also known as African sleep disease or somnolly encephalitis, is a zoonotic parasitic disease transmitted by the bite of Trypanosoma brucei through tsetse flies, commonly known as tsetse flies.

The disease is endemic in west-central Africa, particularly in sub-Saharan Africa, where prevalence is as high as 80% in some endemic areas.

After the patient is bitten by Drosophila, the trypanosomes enter the patient's bloodstream from the Drosophila, and the initial reaction is only local skin swelling, and a red spot appears in the center, which is the chancre of the chapanosoma, and the local skin lesions are self-limited and can resolve after three weeks.

After entering the hemolymphoid stage, trypanosomes enter the blood and interstitial lymphatic fluid, and persist in the blood and lymphatic system for a long time, causing extensive lymphadenopathy and a series of pathological changes.

The main clinical symptoms are personality changes, asexual state, and abnormal reflexes, such as deep hyperesthesia, ataxia, tremor, spasms, drowsiness and lethargy.

The course of Trypanosomiasis can last from years to months, culminating in central nervous system abnormalities and, if left untreated, often death, in lethargy. ”

Lu Li quickly finished talking about what he had read in the textbook, and Gu Yanan nodded with satisfaction, "Yes, I have learned the basic knowledge very solidly, so come with me to the hospital." ”

Wang Xiaoxiao also wanted to follow, Gu Yanan glanced at the emergency office, Zhou Jie and Gao Fei had already gone to the suburban investigation site, and Wang Xiaoxiao was the only one in the office.

Gu Yanan: "We must leave one person in the emergency office, and I will take you with me next time I go to the investigation site, and when the results of this investigation come out, I will show you all the files and processes." ”

Lu Li also echoed and said, "Yes, you have to listen to Director Gu's arrangement, you stay at home and watch the door." ”
