The hospital security guard was called in, and only then did he barely separate the scufflers.

Although he was separated, the man kept rushing forward, cursing and swearing in his mouth, and the two big men barely restrained him.

Gu Jiashu stepped forward and asked the onlooker nurses, "What's going on?" ”

The little nurse rubbed her sore arm and said angrily, "There is a 17-year-old boy who needs a liver transplant, and his father insists on being a donor himself, but after checking the blood, he found that he is type AB, his wife is type A, and his son is type O blood, so he suspects that his son was born by his wife and someone else." His wife swore to the sky that it was really his son, but the man didn't believe it and beat his wife. ”

Gu Jiashu glanced at the little sister beside him, and then walked up to the fighting man with disdain, "Have you ever heard of homeopathic AB blood?" ”

The man froze, his eyes blank.

He's only heard of ABO blood type, and as for what cis trans, he really hasn't heard of it.

Gu Jiashu's tone was still light, "If you are homeopathic AB blood, your wife is A blood, you may also give birth to type O blood, although the probability is low, it is still possible." ”

The man who fought was completely stunned, since it was the doctor who said it, it was true.

Next to him, his wife cried even more sadly.

The little nurse who had been pushed down just now glanced at the man, and said in a voice that was not big or small, but just happened to be heard clearly by the people around her, "Ignorance is terrible! ”

A fight was stopped by Gu Jiashu with a few words.

Xiao Chu gave Gu Jiashu a thumbs up.

Gu Jiashu patted the shoulder of the little sister beside him and said in a comforting tone, "There are more than 1,000 human blood types, and there are many strange blood types in reality, and it is not possible to judge whether there is a blood relationship based on the blood type. ”

Gu Yanan squeezed out a smile, "Well, my brother is an expert in this area, and I listen to my brother." ”

Zhou Lao felt that the conversation between the two brothers and sisters was a little strange, but he didn't know what was strange, but Xiao Chu was thoughtful.

Marina District, Little Red Flower Kindergarten.

By the time Lu Li's CDC team arrived, the kindergarten gate had been locked.

The people are not there, but the flow work must continue.

The staff teachers of the kindergarten, as well as the children in the kindergarten, should be investigated.

Lu Li first contacted Gu Yanan, and obtained the list and address of the employees and kindergarten children through Director Li, and prepared to go door-to-door to inspect them.

Although the Little Red Flower Kindergarten is small, there are more than 100 children studying here, and the workload is very large.

According to the principle of territorial management, Lu Li contacted the people of disease control in the coastal area, and all of them were dispatched to cooperate in the division of labor.

In the middle of the night, people from the disease control knocked on the door of the kindergarten children's homes wearing protective clothing, conducted physical examinations and samples on the children and their families, and instructed the families to disinfect the environment in the house.

At 4:30 a.m. on the second day, the flow work of Xiaohonghua Kindergarten ended.

Lu Li and his entourage brought the collected specimens to the laboratory of the Municipal Center for Disease Control and Prevention.

The laboratory department received the second batch of specimens, and at the same time fed back the results of the specimens brought by Gu Yanan from the hospital yesterday evening.

8:30 a.m.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan was talking on the phone with Section Chief Li of the Laboratory Department.

"Director Gu, the nucleic acid test results of the two batches of samples sent yesterday have come out and have been sent to your mailbox, and the tox nucleic acid of the bacteriophage toxin gene of rod-shaped susceptible bacteria in diphtheria is positive. Bacterial culture is ongoing, and results are estimated to be available for another two days. ”

"What about Elek's plate experiment?"

"I haven't done it yet, but this experiment must be done, even if Corynebacterium diphtheria is isolated, and the TOX gene is positive, but the table does not express the toxin, we still have to do this immunoprecipitation experiment, and we will feedback to you as soon as the results are available."

Gu Yanan opened the mailbox and called up the test results.

As a nucleic acid detection technology, PCR is currently the shortest detection time and the fastest result.

The gene of Corynebacterium diphtheria was detected in the bodies of Principal Li, Elder Li Yuan's wife, and kindergarten child Lele.

Other kindergarten staff and children did not test positive in their bodies.

No positive tests were detected in the external environmental specimens.

Gu Yanan speculated based on the onset time of several patients that Elder Li Yuan's wife was the first to be inspired, and then passed the germs to Principal Li, who in turn passed the germs to the kindergarten child Lele when he was working in the kindergarten.

Other kindergarten staff and children have not been infected for the time being.

For diphtheria, an ancient disease, the human being is the main source of infection, and now that all three sources of infection have been controlled, the epidemic is temporarily under control.

But where did the first patient, Dean Li's wife, get infected?

Gu Yanan looked through the previous flow records and found that the flow information of Elder Li Yuan's wife showed that he used to wipe his eyes with a tissue before the onset of the disease.

Corynebacterium diphtheria exists in the external environment, and this bacterium should be present in the usual living environment of Elder Li Yuan's father.

Gu Yanan decided to conduct flow survey sampling at Director Li's house.

Does Corynebacterium diphtheria in the environment continue to infect other people?

On the one hand, controlling the source of infection and cutting off the route of transmission is to strengthen the immunity of the population, and generally strengthen the vaccination of susceptible groups with one shot of diphtheria-pertussis triple vaccine.

Several members of the emergency response team began to split up again.

A group went to Director Li's house to take samples of the external environment.

The other group urgently allocated a batch of tetanus-pertussis triple vaccine from the vaccine manufacturer to organize on-site vaccination for kindergarten workers and children.

The home of Director Lee.

This is an ordinary residential building in the coastal area.

Mr. Li's family lives on the top floor, with 3 bedrooms and 2 living rooms, plus an attic and an open-air balcony garden.

Director Li's children are all out of town, and he usually lives here with his wife.

The house is clean and tidy, with a few birds, and flowers and plants all over the balcony.

According to the prompt of his wife who grew up with Li Yuan, Gu Yanan found the facial tissue he used often.

Xiao Chu carefully inspected these facial tissues, "I haven't seen this brand of facial tissues." ”

Zhou Lao: "Miscellaneous brands, there is not even a manufacturer and production date on it." ”

One of the packets was opened and put into a sampling bag.

There were also a large number of spare facial tissues in the storage room, and Gu Yanan picked out a few packs from them, put them into sampling bags, and put them into sampling boxes.

After collecting facial tissues, samples were collected from other places such as washbasins, bathrooms, and bedrooms, and the entire house was terminally disinfected.

10:20 a.m.

Little Red Flower Kindergarten Playground.

Medical staff from the CDC and community hospitals formed a temporary vaccination team to vaccinate hundreds of children in the playground.

Health care workers are busy administering vaccines.

Lu Li, Wang Xiaoxiao and Gao Fei coordinated and distributed diphtheria prevention brochures to parents.

Residents in the surrounding communities also came to see the excitement when they saw this situation, knowing that there was an outbreak of white monkeys, they consulted one after another, and some people also wanted to strengthen their immunity with a shot of diphtheria.

An old lady in her 60s pushed her little grandson to hang out here, and when she saw that there were many people coming to join in the fun, she didn't feel scared when she heard that it was an infectious disease, and she took the initiative to come over and find Wang Xiaoxiao, who was distributing promotional materials, "Girl, my wife also wants to get vaccinated, is she going to your CDC to get vaccinated?" ”
