Thinking of this, Gu Yanan suddenly had another clue.

The red-billed finch is a species of bird, and a pathogen that birds often carry is capable of causing symptoms of pneumonia in humans.

Psittaci hot chlamydia!

It is not in the respiratory tract nine pathogen tests.

It can cause symptoms of pneumonia in humans, which are very similar to colds in the early stages of the disease.

It can infect bird keepers, and the initial symptoms of infected people are much like the flu.

Uncle Ge has a lot of birds at home, which meets the conditions for transmission.

Gu Yanan immediately called his colleagues in the CDC lab and asked them to test for Chlamydia psittaci.

Two hours later, the test results of the CDC came out, and the nucleic acid of Chlamydia psittaci was detected in the sample of Uncle Ge's lung wash.

Uncle Ge was indeed infected by Chlamydia psittaci.

After finding the pathogen of infection, Gu Jiashu immediately changed Uncle Ge's treatment plan and replaced it with tetracycline, a special drug for Chlamydia psittaci.

Find the pathogen and change the treatment plan, this matter is not over here, Gu Yanan must find the source of infection, cut off the transmission route, and eliminate the source of infection, so that Uncle Ge can be truly safe.

Gu Yanan explained the reason for his illness to Uncle Ge instead of Gu Jiashu, "Uncle Ge, your illness this time is likely to be related to the birds you raised, so I want to go to your small courtyard to check, if Chlamydia psittaci is really detected in their bodies, your birds can't stay." ”

Uncle Ge was very distressed, "Do all the birds have to be disposed of?" ”

"We can test all the birds individually, and if there is Chlamydia psittaci infection, it has to be disposed of."

Although Uncle Ge felt very sorry for the birds he had raised for many years, he still agreed for the sake of his life, but he asked, "I have been raising birds for decades, and I have never had an accident before, why did something go wrong this time?" ”

Gu Yanan also felt strange, "Have you bought a new bird recently?" Or when you go out to walk the birds, do you come into contact with other birds? ”

Uncle Ge thought for a while, "My friends who walk birds are very professional and won't let others touch them easily, but recently I really bought two budgies, which are from the largest flower and bird market in Lianhai City, Qingheyuan Flower and Bird Market, and I exchanged two budgies for them. ”

In the evening of the same day, the small courtyard of Uncle Ge's house.

Gu Yanan got the key to the courtyard from Uncle Ge, put on a protective mask, and entered the courtyard alone.

There is a glass flower house in the yard, there are a lot of tropical flowers and plants planted in the flower room, there are some temperate plants outside the flower room, and there are many bird cages, and there are more than a dozen of them as far as the eye can see.

Gu Yanan inspected the bird cages one by one, and when he checked the seventh, he found that there were two budgies inside, one of which had fallen to the bottom of the cage and had long since lost his breath, and the other was listless.

Sure enough, there were dead birds.

Chlamydia psittaci is endemic in birds, causing mass deaths in birds and is often referred to as ornithosus, and this pathogen occasionally infects humans, especially young children or the elderly with weakened immune systems.

Uncle Ge is old, and because of the previous infection with Trypanosomiasis, his body has suffered a lot of damage, and his immune system is weak, so he is very susceptible to Chlamydia psittaci infection.

Gu Yanan wore gloves and took out the dead budgie from the bird cage and put it in the sampling bag.

After that, the guano in each cage and the soil around the cage were sampled.

After the specimen was collected, Gu Yanan sent the specimen to the CDC laboratory first, and she went back to the hospital to take care of Uncle Ge.

——

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

Outside Uncle Ge's hospital room.

Gu Yanan was asking his brother Gu Jiashu about Uncle Ge's condition.

Gu Jiashu: "After switching to tetracycline, Uncle Ge's infection has been controlled, and according to this trend, he should be discharged from the hospital soon." ”

Gu Yanan breathed a sigh of relief, fortunately, the pathogen was found in time.

Gu Jiashu patted the little sister lightly on the shoulder, "Uncle Ge's situation is a sporadic case of Chlamydia psittaci infection, it stands to reason that your CDC will not carry out individual cases of pathogens of this level, you are so attentive to Uncle Ge, it won't be because of Nan Hanfei, right?" ”

Gu Yanan was stunned by his brother's question, and when he thought about it carefully, it seemed that he really helped Uncle Ge at the beginning because of Nan Hanfei.

But Gu Yanan didn't want to admit it, and found a reason for his actions, "Didn't you say that our disease control is lenient, not only cluster cases, even if it is a relatively rare case, we will actively investigate." ”

Gu Jiashu smiled meaningfully.

Gu Yanan wanted to explain again, but suddenly, a young doctor from the infectious disease department hurriedly ran over and reported to Gu Jiashu, "Doctor Gu, two more patients with severe pneumonia were transferred to the hospital just now. ”

A new patient was admitted to the hospital, Gu Jiashu rushed to deal with it, just took two steps, and remembered that the little sister was still behind him, so he turned back to Gu Yanan and said, "Severe pneumonia patients are a routine monitoring project of your CDC, and they need to be sampled and sent for testing. ”

"Okay, I'll go with you."

Two newly admitted patients with severe pneumonia in the ward.

An old man and a young man lie in two adjacent hospital beds.

Accompanied by family members.

The old man was an old man in his 60s, and the child was a little boy of four or five years old.

The accompanying family members were an old lady and a young couple, and from their conversations, they knew that the elderly, the children and the family members were a family.

There must be a connection between two patients with severe pneumonia in the same family at the same time.

Gu Yanan stared at the nurse and took blood and nasopharyngeal swab specimens for an old man and a young man.

With the specimen in his hand, Gu Yanan felt that it was necessary to learn some basic flow information from this old and young person.

Gu Yanan first looked at the medical records of the two, the old man is a grandfather named Li Qiang, and the child is a grandson named Li Lele, who lives in Xinghai Garden Community, Dongcheng District.

Gu Yanan asked Grandpa Li, "Do you usually live with your grandson's family?" ”

Grandpa Li had difficulty breathing, and he was a little wheezing when he answered, "I don't live together, my wife and I live upstairs, and my son's family lives downstairs, but we usually eat three meals a day together." ”

Although they don't live together, they are very close.

"Did you have any special experiences before you and Lele got sick?"

"Special? No, I take Lele to and from kindergarten every day, and sometimes go to the vegetable market to buy vegetables, and my life is very regular. ”

"Do you have air conditioning at home?"

"There is an air conditioner at home, but it is not turned on yet, it is only early summer, and the weather is not very hot, but there will be an electric fan at noon." Grandma Li saw that her wife was panting badly, so she answered Gu Yanan's question on behalf of her wife.

"When you go to the vegetable market to buy vegetables, have you ever come into contact with live poultry?"

Grandma Li hurriedly replied, "My wife is usually responsible for picking up Lele, and I do the work of buying vegetables, and he will only buy some small vegetables when he buys vegetables once in a while, and I buy live poultry such as chickens and ducks." ”

Gu Yanan was about to end the inquiry, when her daughter-in-law, who had been silent on the side, suddenly spoke, "Last weekend, because the kindergarten allowed children to bring small animals, grandpa took Lele to the flower and bird market near the community. ”

Just experienced the incident of Uncle Ge being infected with Chlamydia psittaci, and the first pathogen that Gu Yanan thought of was related to birds.

"Ever been to the flower and bird market? Have you ever been exposed to a sick bird? Or a healthy-looking bird? ”
