An ulcer has formed in the center of the papule area of the wrist.

Itching, pimples, ulcers......

This is most likely a skin lesion caused by a fungal infection.

And Uncle Li has been exposed to pigeon droppings again.

Cryptococcus neoformans may be the causative agent of this skin lesion.

Plus his chronic cough symptoms.

Uncle Li may also have been infected with Cryptococcus neoformans in pigeon droppings and has developed skin and lung symptoms.

Gu Yanan asked Uncle Li, "Do you have underlying diseases?" For example, diabetes, high blood pressure and the like. ”

"I have diabetes for more than 10 years, and I have been taking insulin."

With the underlying disease and the history of contact with the source of infection, Gu Yanan has already concluded in his heart that Uncle Li was infected with Cryptococcus neoformans.

A look at Xiao Chu, Xiao Chu immediately opened the sampling box, took out a cotton swab, and said to Uncle Li: "Stretch out your hand, I want to collect the ulcer exudate from your wrist." ”

Uncle Li stretched out his hand very cooperatively, but his eyes asked, "Why do you want to take a sample from me?" Am I sick? No, I've always been sick, I'm asking if my illness is related to my wife's illness? ”

Xiao Chu didn't know how far to explain to Uncle Li, and looked at Gu Yanan for help.

Gu Yanan: "We suspect that you and your wife are infected with the same pathogen, and we recommend that you go to the hospital for a detailed examination, and the medicine you are taking now cannot cure your disease." ”

Uncle Li knew the severity of his wife's illness, and if it was really as the disease control person said, he must go to the hospital for examination, "Okay, I'll go now, I'll call my son and ask him to pick me up." ”

Uncle Li immediately called his son, and Zhou Lao and Lu Li disinfected Uncle Li's house with the disinfectant spray they brought, and finally did not forget to instruct: "In the future, you should wear gloves when cleaning up pigeon droppings, and it is best to pull up protective nets on the attic balcony to avoid pigeons and wild birds from pooping again." ”

——

After 3 hours.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan received a nucleic acid test report from the laboratory.

The specimens of Old Man Zhang, Mrs. Li, Father Gu, and Uncle Li were all positive for Cryptococcus neoformans nucleic acid.

Environmental samples from the attic of Old Man Zhang's house, the balcony of Daddy Gu's house, and the attic of Mrs. Li and Uncle Li's house were all positive for Cryptococcus neoformans.

The outbreak in the Xinhai Garden Community was determined to be caused by Cryptococcus neoformans infection in pigeon droppings.

An epidemic summary report has taken shape in Gu Yanan's mind.

Old man Zhang, a resident on the top floor of Building 14 of Xinhai Garden Community, raised a flock of pigeons, and the pigeon droppings contained the pathogen Cryptococcus neoformans.

Old man Zhang was infected, showed symptoms of pneumonia and meningitis, and accidentally fell from the building while cleaning up pigeon droppings.

The pigeons went to the next building 13 to forage for food, leaving pigeon droppings on the roof balcony of Mrs. Li's house, Mrs. Li and Uncle Li were infected during the cleaning process, Mrs. Li had symptoms of pneumonia, and Uncle Li had symptoms of pneumonia and skin ulcers.

There was also pigeon droppings on the balcony of Daddy Gu's house, who lived downstairs from Old Man Zhang, and Daddy Gu was infected during the cleaning process.

Although Cryptococcus neoformans is widespread, it is usually only infectious to people with low immunity, so although Gu's mother was also exposed to the pathogen, she did not get sick.

As long as the source of pigeon droppings is cleaned up and the transmission route is cut off, the Cryptococcus neoformans epidemic in the Xinhai Garden Community can be controlled.

Gu Yanan forwarded the report to her brother Gu Jiashu, and learned on the phone that the patient had improved after treatment.

After talking about the patient's condition, his brother Gu Jiashu talked about the people sent to the hospital by Gu Yanan.

"Little sister, who is the person you sent here today? I haven't seen it before, and I haven't heard you mention it, what about Nan Hanfei? ”

"Oops, I forgot about that." Gu Yanan patted his head, "I was busy with the flow of things, and I forgot all about the things you told me to find someone to go to the hospital to relieve you, I didn't call Nan Hanfei, and I didn't let anyone else over, who is the person you saw?" ”

Gu Jiashu on the other side of the phone was confused, "You didn't let people come?" But he said it was your friend, or a neighbor, or your colleague's brother. ”

There are so many identities, is it him?

"Chu Qingfeng?!"

"Yes, when he introduced himself, he said that his name was Chu Qingfeng, and he was chatting with his mother now, this kid was quite good at making the old man happy. I just heard them chatting a little bit, like they were talking about when you were a kid. ”

"How did Chu Qingfeng know that his father was sick and hospitalized? He went to see his dad specifically? Gu Yanan asked.

"He's your friend, how can I know about something you don't even know? Little sister, what is your situation now? Shouldn't it be Nan Hanfei who came over today? ”

Gu Yanan didn't know what the situation was now, so he naturally couldn't answer his brother, "I don't know, the CDC is almost busy here, I'll go to the hospital immediately." ”

Before going to the hospital, Gu Yanan arranged tasks for Zhou Lao and Gao Fei, asking them to go to the homes of three sick households in Xinhai Garden Community with the sanitizing department to disinfect the external environment again, and do a good job in publicizing the correct and safe breeding of pigeons in the surrounding community.

Xiao Chu saw that he didn't arrange a job for him, so he hurriedly asked: "Sister Yanan, don't you need to disinfect the external environment of the entire Xinhai Garden Community?" ”

"No, Cryptococcus neoformans originally exists in the external environment such as soil and bird droppings, and it is impossible for humans to completely eliminate these fungi, as long as the patient's home environment is disinfected, and the large-scale external environment disinfection effect is not good, and it will also cause environmental pollution."

"Oh." Xiao Chu was thoughtful.

Gu Yanan thought of Chu Qingfeng, and when he was already about to leave the office, he turned back to Xiao Chu and asked, "You told your brother about my father's hospitalization?" ”

Xiao Chu was stunned for a moment, and then shook his head, "No!" ”

After a moment, Xiao Chu seemed to remember something, "Oh, by the way, my brother called me before and asked me what I was doing, at that time we were asking patients in the hospital, and I casually said 'I work in the hospital, there is a colleague's father hospitalized, and I and the team leader are investigating'." That's all I said. And I didn't say that your father was hospitalized. Sister Yanan, is there anything wrong with my brother? ”

"It's okay, your brother has a heart."

It's too hearty.

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

In Gu's father's ward, Gu's mother and Chu Qingfeng were chatting beside the bedside.

Gu Yanan entered the ward, and Chu Qingfeng stood up with a smile, "Yanan, you're done, just have me take care of your uncle." ”

Chu Qingfeng's words fell into Gu Yanan's ears, making people a little uncomfortable.

It always feels a little strange that someone who is not related to you suddenly takes care of you and your family.

Chu Qingfeng was because of his younger brother, so he deliberately showed favor to his younger brother's boss?

It's completely unnecessary.

Gu Yanan smiled politely, "Thank you for your kindness, but don't bother you, my dad can have me and my brother here." ”

"It's okay, take care of your family, I'd love to."

Gu Yanan was unhappy, and his smile froze for a moment, "Mr. Chu must be busy with work, just take care of me here." ”

Gu's mother felt her daughter's attitude, and hurriedly diverted the topic, and said to Chu Qingfeng happily: "Xiao Chu has a heart, come to see your Uncle Gu still bring fruits, and when your Uncle Gu is discharged from the hospital, bring your younger brother Qinggeng to the house to play." ”

"Okay, I'll definitely go, and when Uncle Gu is discharged from the hospital, call me, and I'll pick it up myself." Chu Qingfeng took out a business card and handed it to Gu's mother.

Gu's mother took it, looked at it carefully, and smiled, "Xiao Chu is so young, I didn't see that he is the general manager of such a large group, and his future is limitless." ”

Being praised by Gu's mother, Chu Qingfeng was very happy, there was some smugness in his eyes, he turned around and handed Gu Yanan a business card, and said with a smile: "Yanan, this business card has my private number in it, and we can contact each other often in the future." ”

Gu Yanan always felt that Chu Qingfeng was very strange today, but he couldn't say what was strange, he accepted the business card and smiled politely, "Xiao Chu works in my group, and you, as a family member of my colleague, we will definitely be able to meet often." But as Xiao Chu's leader, he can't trouble his colleagues' families, otherwise he will be suspected of taking bribes. ”
