The First People's Hospital of Lianhai City, Infectious Disease Ward.

A young man in his mid-twenties-fourteens was lying on a hospital bed, the white quilt of the hospital covering his chest, his arms exposed, one of which was hanging from a drip.

The young man is very thin, it can be described as skinny.

Sitting next to the hospital bed was an old man in his fifties and sixties, with gray hair, looking at the young man on the hospital bed and wiping his tears.

Gu Yanan and Lu Li stood outside the ward, looking at everything in the ward through the glass door of the ward.

Lu Li sighed quietly: "This patient looks like he has reached an advanced stage, even if he is treated now, I don't know if he can save a life." ”

"How do you see that?"

"There is an abnormality in the electrocardiogram monitoring next to his bedside, indicating that he has myocarditis, coupled with his thin body, and involuntary tremors in his hands and feet, indicating that the nervous system has been affected, and these symptoms have obviously reached an advanced stage, and, most importantly, on the way to the hospital just now, you showed me his hospital examination report, his cerebrospinal fluid examination is abnormal, and the book says that if the cerebrospinal fluid is abnormal, the prognosis is poor, and the cure rate is only 30%."

"Well, yes, I observed it carefully."

Lu Li was praised twice by Gu Yanan in succession, and he felt a little proud, and was about to push open the door of the ward and go in to ask, but was stopped by Gu Yanan.

"Wait a minute, wait until his attending doctor arrives, understand the basic situation, and then go in together."

Lu Li knew Gu Yanan's worries, they had come to the hospital to conduct a miscarriage investigation, and the patient's family only trusted the attending doctor and remained vigilant against unfamiliar disease control personnel.

After being introduced by the attending doctor, the patient and his family will be more likely to accept the interview of the CDC.

After waiting for a while, there was no attending doctor, Gu Yanan and Lu Li took the initiative to go to the doctor's office.

When I inquired in the doctor's office, I learned that the attending doctor of the sleeping sickness patient was performing an operation and would not come out until at least an hour later.

Gu Yanan found his brother Gu Jiashu, and Gu Jiashu happened to be free, so he helped Gu Yanan call up the detailed medical files of the sleeping patient.

Gu Yanan carefully looked at the patient's medical history in the file.

Gu Yanan frowned slightly, "The patient has been to so many hospitals before, but none of them have been diagnosed?!" ”

Gu Jiashu sighed, "The primary medical units do not have enough understanding of this rare disease, so they missed the best time for diagnosis and treatment. ”

Lu Li was very concerned about this patient, and asked Gu Jiashu, "What will be the patient's prognosis?" ”

"Because the patient's condition has affected the central nervous system, we have treated with organoarsenic, and the prognosis depends on the individual response, but according to the previous literature, the prognosis is mostly poor as long as the central nervous system is involved."

The doctor's statement is consistent with what Lu Li saw in the book.

Lu Li's heart was extremely heavy when he thought of the scrawny young man on the hospital bed and the elderly people who accompanied him beside the bed.

Gu Yanan broke the atmosphere, "We have to do an on-site epidemiological investigation, and the first thing we need to ask is the patient's condition, Doctor Gu, is it convenient to go with us?" ”

Gu Jiashu knows her little sister, and whenever she comes to work, she has such a serious tone.

Gu Jiashu's tone was very humorous, "Since the leadership of the CDC asks for it, of course our doctors will cooperate." ”

Back in the ward, the young man on the bed was still unconscious.

The elderly man who was accompanying him to the hospital bed saw Gu Jiashu, stood up, and asked nervously, "Doctor, why hasn't my son woken up yet?" He's been sleeping for a day and a night. ”

Gu Jiashu said honestly, "Because the patient's lesions have involved the central nervous system, the effect of organic arsenic treatment varies according to the different course of the disease, and this sleeping sickness is contagious. ”

"What do you want to know? Tell you all that I know. "The old man's attitude was very cooperative.

Lu Li recorded on the side, and Gu Yanan began to ask.

"What is your relationship with the patient?"

"I'm his dad."

"Has your son ever been to Africa before?"

"Nope."

Gu Yanan felt strange that Trypanosomiasis only occurs in Africa, and there are no primary cases in China, and some provinces have reported Trypanosomiasis before, but in the end they were all confirmed as imported cases, and all the patients have been to African epidemic areas.

"Are you sure your son hasn't been to Africa? Did he have been there before, and you didn't know it? ”

"No way, my son has been with me since he was born, he didn't have a mother when he was a child, I took him out of the countryside, went to school in the city for nine years, and came out with me to work when he was 18 years old, usually we do carpentry, although the place of work is not fixed, but we have always been together, it is impossible for him to go to Africa."

Lu Li suddenly asked, "Then have you ever come into contact with people or animals who have come back from Africa?" ”

The old man thought for a while, shook his head and said, "This is not clear, we usually do contract work, and we will go to other people's houses to do carpentry when their houses are renovated, and the people we contact are also landlords or contract foremen, whether they have been to Africa, I don't know." ”

Gu Yanan asked again, "When did your son start showing symptoms of drowsiness?" ”

"About a year ago, he began to often say uncomfortable, want to sleep, at that time I thought he was tired, let him rest more, but did not get better, he often lost his temper with me, my son used to be very docile, but a year ago began to get angry inexplicably, sometimes quarrel with others, not to mention, two months ago the symptoms began to worsen, often do work on the fall asleep, and began to lose weight, I took him to the hospital to see, did not find any disease, and finally the doctor let us transfer to the largest hospital in Lianhai City, I just knew what kind of sleeping sickness I had, hey, I should have brought him earlier, I was afraid of spending more money at the time, I thought it was a minor illness, and I regretted it......"

The old man wiped tears from his eyes as he spoke.

Gu Yanan thought to himself, according to what the old man said, the patient was infected with trypanosomes at least a year ago, but he was sure that he had never been to the African epidemic area, so where did the trypanosomes in his body come from?

The transmission chain of Trypanosomiasis is that the tsetse fly bites a domestic animal or a patient containing trypanosomes, the trypanosomes multiply in the body of the tsetse fly, and when the tsetse fly containing trypanosomes bites a healthy person again, the trypanosomes enter the healthy person, and the healthy person becomes infected with trypanosomiasis and becomes a person with trypanosomiasis.

This is a closed chain of transmission, without which the disease cannot be transmitted.

The domestic environment is not suitable for the breeding of tsetse flies, and the transmission chain cannot be formed, so even if there are imported cases, the epidemic will not further expand.

The main question now is where the source of trypanosomes comes from, that is, how exactly did the patient become infected with Trypanosomiasis?

Gu Yanan asked, "Where was your main place of work a year ago?" Who have you been exposed to in contact with people and animals? The more specific, the better. ”
