Gu Qingcen: "What we need to investigate mainly includes demographic characteristics, such as gender, age, occupation, place of residence, and marital status.

History of exposure, including type of residence in the month prior to onset, history of outdoor activities in the two weeks prior to onset, labor history, history of exposure to wild animals, history of breeding animals, history of tick exposure, skin damage, and contact with similar patients.

As for others, such as clinical features, diagnosis and treatment procedures, laboratory sampling and testing, etc., have been done before. ”

Wang Xiaoxiao knew that Gu Qingcen had a background in related majors before, but he didn't expect him to be so powerful, and he could tell the essence of the on-site flow with a casual remark.

Wang Xiaoxiao was dumbfounded, reacted for a long time, and asked casually: "Gu Dashen, I heard that you just came back from abroad, and you shouldn't have any job now, do you want to consider coming to us to work in disease control?" ”

Gu Qingcen was silent for a moment, and then smiled slightly, "You can consider it." ”

Wang Xiaoxiao didn't expect that she would say it so casually, Gu Qingcen actually said that she would think about it, but then thinking about Sister Yanan's work in disease control, he and Sister Yanan are childhood sweethearts, so he rushed to get close to Sister Yanan, and it is not surprising that he wants to come to work in disease control.

The flow investigation work in Huaguo Village is going smoothly.

The affected villagers all had a history of tick bites or had a history of contact with a tick bite patient.

Although she has not been bitten by a tick, she has caught ticks on her teddy dog, commonly known as grass crawlers, and also squeezed the ticks with her fingernails, and the blood of the ticks is stained all over her fingers.

The blood of a tick with the new bunyavirus entered her through a wound on her hand, which was the route of infection for the flower lady.

As for the first case, Zhang Lishan, through questioning of his wife, the route of infection was clarified.

It turned out that Zhang Lishan had also been bitten by a tick a week ago.

Zhang Lishan was bitten by a tick in the calf while pulling weeds in a tea plantation, and when he returned home, he found that the tick had sucked enough blood and his body was swollen to the size of a mung bean.

Zhang Lishan casually slapped the tick to death, but the tick's mouth remained in his body, and the new bunyavirus carried by the tick also entered Zhang Lishan's body.

The virus multiplied, and Zhang Lishan immediately developed typical symptoms of fever with thrombocytopenia syndrome: fever, bleeding......

When Lao Li Tou and Zhang Lishan clashed in the tea garden, Zhang Lishan's body caused massive pulmonary hemorrhage under the action of external forces, which already had a tendency to bleed, resulting in death.

Once the source of infection and the route of transmission of the epidemic have been identified, the next prevention and control work will be easier to do.

Avoid tick bites in the first place.

Gu Qingcen took people to Huaguo Village and surrounding villages to promote anti-tick bites.

At the same time, in order to understand the distribution of the new bunyavirus in the whole Lianhai City, Gu Qingcen and Gu Yanan discussed and led the disease control team to investigate the status and relevance of the infection of the new bunyavirus among people, vectors, and hosts in the natural village where the outbreak occurred and the surrounding villages.

First of all, the population survey, mainly to collect blood samples from the villagers in the natural village, the workload is relatively large, the municipal disease control emergency team mobilized the local county and district disease control staff to help, in addition to blood collection, but also filled out the case investigation form.

Secondly, the vector investigation is mainly the investigation of the distribution of ticks and the natural rate of virulence.

In order to find out the distribution and poisoning rate of ticks, it is necessary to go to the farmland and mountains around the natural village to catch ticks, this workload is not small, Gu Qingcen personally wore protective clothing to catch ticks in the wild, Wang Xiaoxiao and Lu Li followed aside, looking at Gu Qingcen's familiar appearance, and sighed in his heart, it seems that he is not the first time to do this kind of disease control work, but a veteran.

In addition to population surveys, vector surveys, host surveys are also conducted.

In the natural village where the outbreak occurred, poultry such as chickens and ducks, domestic animals such as cattle and sheep, wild rats, hares, and hedgehogs, rodents such as wild mice, hares, and hedgehogs, and small mammals were investigated in the places where patients often lived.

A lot of poultry, livestock, and wild animals were caught, blood samples were collected, and some organ specimens were sent to the laboratory of the Municipal Center for Disease Control and Prevention for nucleic acid testing of total serum antibodies and viruses.

A large number of positive specimens were detected and then used for isolation and culture of the virus.

Finally, 32 strains with complete case information were selected from the isolated novel bunyavirus for whole genome sequencing and gene characteristics analysis.

The genetic phylogenetic tree of the new bunyavirus isolated from this outbreak was constructed, and the homology comparison and molecular evolution analysis were carried out with the new bunyavirus from other parts of the world and other provinces in China.

The vicinity of Huaguo Village, Yuntai Township, Lianhai City, has been identified as a natural foci of the new bunyavirus.

While Gu Qingcen and other members of the emergency response team investigated the outbreak of the new bunyavirus in Huaguo Village, Gu Yanan was being treated for the sequelae of the Ebola virus in the hospital.

By the time Gu Yanan was discharged from the hospital, Gu Qingcen had already analyzed and sorted out the investigation data of the outbreak into a report paper model.

——

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan sat behind his desk, and on the table was the epidemic report compiled by Gu Qingcen.

Gu Qingcen stood lightly in front of Gu Yanan's desk.

Mr. Zhou and Gao Fei have completed academic exchanges and returned to the emergency office.

Lu Li and Wang Xiaoxiao are the main team members who dealt with the outbreak, and now that Gu Yanan has returned from the hospital, the two planned to take the initiative to report the recent work to her, but thinking of the degree of contribution to the investigation of the outbreak, they silently retreated.

The five members of the emergency team were all there, plus a Gu Qingcen who had just arrived.

The eerie silence in the emergency office at this time.

Everyone seemed to be busy with their own business, but everyone's ears were pricked up, looking forward to the situation when Gu Yanan and Gu Qingcen met for the first time in the office.

Because of Gu Qingcen's outstanding performance in the outbreak of the new bunyavirus epidemic, Director Yang of the Lianhai CDC decided to hire him as an external expert of the CDC, and his office is located in the emergency office, which is a member of the emergency team.

Gu Yanan glanced at the report sorted out by Gu Qingcen, this report was written with clear ideas, complete data, and novel views, and could be directly published as a paper.

Gu Yanan looked up and stared at Gu Qingcen, she didn't understand what happened 7 years ago that made his childhood sweetheart disappear without a sound.

Why did a person who had disappeared for 7 years suddenly return to her and approached so actively, his intention was felt by everyone to be close to her, but was the real intention really like that?

The injuries that had been made Gu Yanan very suspicious.

But Gu Qingcen's professional ability is indeed beyond doubt, Director Yang of the center has agreed to him as an external expert, and Gu Yanan will not say anything.

"You've decided? Do you really want to work at the Lianhai CDC? Become a colleague with me? Not going abroad? ”

A series of questions asked.

Gu Qingcen nodded seriously, "Yes, I won't leave again." ”
