But Wang Xiaoxiao knew the convention, and without waiting for Gu Yanan to speak, he spoke first, "I checked whether there is any case information related to meningitis on the Internet of the epidemic. ”

"Okay, let the hospital send the details of this case in a while, and you will search according to the case information with a smile."

"Understood!"

——

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

In Gu's father's ward, Gu Yanan and Xiao Chu wore masks and dressed in protective clothes during the on-site investigation.

Gu Jiashu accompanied him as the attending doctor.

It was the first time that Gu's father saw his daughter at work, and although he was proud of his daughter, he also knew the danger.

Gu's father complained about his son, "Kashu, why did you let your sister come?" My disease is likely to be contagious, and your sister is too dangerous. ”

"Dad, don't blame my brother." Gu Yanan relieved his brother, "My brother is also on business, and your illness this time must be reported to the disease control, otherwise it will be a dereliction of duty by the attending doctor." ”

Dad Gu understood, "My illness this time really needs to be controlled by the disease?" So serious? ”

"The source of the disease has not yet been identified." Gu Yanan patiently explained, "Judging from the current situation, this disease is contagious, so I need your cooperation to answer some questions. ”

"What do you want to know? Just ask. ”

"Where have you been active lately? Have you ever been to a particular place? Especially with Uncle Zhang, who lives on the top floor, and Mrs. Li, who lives in Building 13 next door, have you ever had any contact? ”

Dad Gu thought for a while and said, "Since I retired, the place where I can do my activities is very limited, and I go to the street with your mother every day to buy groceries and go to the park near the community to exercise. As for Uncle Zhang, although he is a neighbor who goes up and down the stairs, he usually doesn't interact much, and it is a relationship of nodding and greeting when he meets, but he rarely goes to the door, and he has rarely been seen recently.

As for Mrs. Li in the next building, I didn't know her at all, let alone any contact. ”

Gu Yanan thought to himself, my father had no contact with the other two patients, so how did he get infected with the same pathogen?

Could it be that you have been exposed to the same external environment?

Gu's mother echoed and said: "Your father is right, he doesn't know Sister Li in the next building, I know, but I don't know each other, and I don't usually have any contacts."

As for the old man Zhang upstairs, I know and have seen him play chess, and a few days ago, your second aunt brought back a lot of fresh vegetables from the suburban farm, and the family couldn't finish it, so I gave some to the neighbors, including the old man Zhang upstairs.

When I was delivering food, I saw that he was coughing all the time, and I asked him if he had a cold, and he said that he had a little cold, and he was taking medicine, and it was no big deal. ”

Gu Yanan frowned slightly, her mother had contact with Old Man Zhang, if the disease was infectious, her mother might also be infected.

Gu Yanan gave his brother Gu Jiashu a look, and Gu Jiashu immediately understood, "I'll check my mother in a while." ”

Gu's father: "When your mother said this, I remembered one thing, more than a week ago, your mother sent vegetables to Uncle Zhang upstairs, and finally Uncle Zhang sent a bag of dried radishes to dry by himself to express his gratitude, but your mother collected it, I was exercising in the park at that time, and I also heard your mother mention it after I came back, will your mother be in danger?" ”

Gu Yanan comforted his father, "Brother will give my mother a comprehensive examination, judging from my mother's current mental state, there is no problem." ”

"Old man, you love to worry about it, I'm alive, what can I do, but it's a pity that the bag of dried radishes sent by Old Man Zhang, a smell of pigeon dung, was thrown away by me."

Dried radish that smells of pigeon dung?!

Gu Yanan was keenly aware that something was wrong.

"Mom, haven't you eaten or tasted those dried turnips?" Gu Yanan asked.

"No, I just smelled it, and I felt a faint smell of pigeon droppings, so I threw it all away."

Father Gu agreed, "Old man Zhang upstairs has a flock of pigeons, and his dried radish must have been contaminated with pigeon droppings when he was hanging on the roof of the building. ”

Gu's mother nodded, "Well, Old Man Zhang usually dresses very cleanly, but every day with a group of pigeons, he can't avoid the smell of pigeons." ”

Gu Yanan realized the problem.

Pigeons, pigeon droppings, meningitis, pneumonia, fungal infections......

Could it be a Cryptococcus neoformans infection?

Gu Yanan said to his brother Gu Jiashu: "It is likely to be Cryptococcus neoformans infection. ”

"Cryptococcus neoformans?!" Gu Jiashu was surprised at first, and then suddenly realized, "If it's Cryptococcus neoformans infection, then it can explain the current situation." This fungus is mostly found in soil and bird droppings, it is a saprophytic fungus that can infect people with weak immunity, and symptoms of pneumonia and meningitis such as fever, cough, nausea, and vomiting appear, but normal people are resistant to it and will not show symptoms. ”

Gu's mother also suddenly realized, "There is pigeon droppings falling upstairs on the balcony of our house, your father cleans up every day, and comes into contact with the fungus in the pigeon droppings, and because I have caught a cold a few times in winter, my health is not very good, so I am infected, I am in good health, even if I come into contact, I am fine."

Upstairs, the old man Zhang came into contact with pigeon droppings every day and was the first to be infected.

Sister Li from Building 13 next door said that there are often pigeons pooping on her balcony, and she has recently had heart surgery, and her resistance is not good, so she is also infected.

Yanan, do you see my mother's analysis right? ”

Gu Yanan gave a thumbs up to his mother, "The analysis is right, your reasoning ability can enter the disease control emergency team." ”

Gu's mother usually listens to and sees her daughter's appearance at work, and naturally she is also influenced by it.

Gu Yanan: "Mom, you can accompany your father here to recuperate, and I will go to the Xinhai Garden Community to do on-site investigation." ”

Gu's mother happily agreed, and added in time: "You have the key to the house, when you go to the scene, help clean up the pigeon droppings on the balcony, and then completely disinfect them." ”

Gu Jiashu smiled and teased his mother, "Mom, are you considered to be a socialist wool?" ”

Gu's mother glanced at her son, "I'm reminding your sister to be careful and meticulous in her work." Oh, by the way, you have time to talk about this here, but I'm going to ask you about the big star Li Jiahui before? I've heard that she often brings you food, how is it doing? Will you be here today? Although I've only seen it on TV, I haven't seen a real person yet, so I must meet my mom this time. ”

Gu Jiashu felt a headache, he knew that it would be a good thing for his mother to be idle here, and sure enough, it was his own mother, and in the process of taking care of his father in the hospital, he could still think of his son's lifelong events.

Gu Jiashu haha, "Oh, Mom, I'm busy here, I'll arrange a physical examination for you, and my little sister has to go to other wards quickly, before going to Xinhai Garden Community for on-site investigation, she also has to ask Uncle Zhang and Mrs. Li." ”

Coming out of Gu's father's ward, Gu Yanan was about to go to Uncle Zhang's ward, but was stopped by his brother Gu Jiashu, "Little sister, wait a minute, I have something to tell you." ”

I thought my brother was going to talk about the patient, but I didn't expect him to say, "Little sister, you come back quickly after dealing with the flow of things, I can't deal with my mother's problem alone." ”

Gu Yanan was very sympathetic to the old brother, and nodded seriously, "Okay, I'll go to the scene as soon as possible to collect environmental samples, and then send them to the disease control laboratory with the patient's specimens, and when the results are out, the pathogen of this epidemic is determined, and then I have done on-site disinfection and publicity, and after writing the epidemic summary report, I will come." ”
