With the results of laboratory tests, combined with the symptoms of the deceased, Gu Yanan confirmed that this was a pneumonic plague outbreak.

Lu Li speculated, "Wang Dequan is the first case of pneumonic plague, and the deaths of other villagers are all due to contact with Wang Dequan." ”

Section Chief Li: "Pneumonic plague can be transmitted through airborne droplets, and by isolating patients, the transmission route can be cut off, but where did the plague bacillus on the body of the first case Wang De come from?" ”

Gu Yanan closed the body bag, "The source of this plague epidemic must be investigated, and the transmission chain must be cut off in time." ”

——

The temporary emergency headquarters at the entrance of Wangjiacun Village, rows of newly built medical tents.

Medical and disease control experts sent by the city, and emergency teams sent by the county health authorities have arrived one after another.

The type of epidemic was determined, and Gu Yanan began to rearrange control measures for the epidemic control team in the temporary emergency headquarters.

The first step is to determine the warning area and the size of the isolation circle to control the spread of the epidemic.

Wangjia Village, Lijia Village, and the neighboring villages of the four surrounding affected villages were classified as warning areas, the two affected villages were classified as large isolation circles, and the affected households were classified as small isolation circles.

In the warning area, the transportation of materials and the entry and exit of personnel are restricted, and disinfection stations are set up on traffic arteries to disinfect personnel or vehicles that must enter and exit the epidemic area.

In the large isolation circle, sentry posts are set up at the entrance of the village to prohibit people from entering and leaving, and villagers are prohibited from visiting each other; Carry out poisonous bait to kill rodents and fleas; Disinfect corpses and cemeteries.

In the small isolation circle, the house, livestock pen and toilet are repeatedly disinfected to eliminate rodents and fleas in time.

The second step is to isolate and treat existing patients and control the source of infection.

Isolate patients in situ.

Except for disease control personnel, who can enter and exit under strict protective conditions, other personnel are strictly prohibited from entering and leaving.

The isolation of patients and close contacts should not be lifted until two weeks after all signs and symptoms have disappeared.

Urgently allocated treatment drugs from the city, mainly streptomycin and sulfonamides.

The third step is to urgently vaccinate against plague to strengthen the immunity of the villagers.

The scope of vaccination is for residents of villages within 5 kilometers along the highway between Wangjia Village and Lijia Village.

There is a shortage of plague vaccines in the city, and vaccine manufacturers are urgently contacted to supply them.

The fourth step is to follow up and observe the health contacts.

In the two villages, dozens of people who had been in close contact with the patient, and hundreds of people who had indirect contact, were followed up and checked, and if suspected symptoms were found, they were given timely medical treatment, and the isolation time was also two weeks.

The fifth step is to publicize and educate and arrange the production and life of villagers in the epidemic area.

Door-to-door dissemination of the symptoms of plague and knowledge of prevention and control allows other villagers to engage in normal production activities except for those who have been quarantined.

After the tasks were assigned, the teams began to move.

The village head, who was familiar with the situation of the villagers, was accompanied by the staff of the county disease control and control, drove the on-site flow shunting of the county disease control, and used loudspeakers to broadcast the knowledge of plague prevention and control in the village in a loop.

Section Chief Li led people to collectively cremate more than a dozen corpses in the cemetery next to the village.

A large amount of accelerant was poured on the body bag, and the fire burned it, and the corpse made a crisp sound.

Soon, all the corpses were reduced to ashes.

Buried the ashes, Gu Yanan fell into deep thought.

Now that the pathogen has been identified, various measures to prevent and control the epidemic are also underway, but it is still unclear where the first case, Wang Dequan, was infected with Yersinia pestis, which is always a hidden danger.

There is another headache for Gu Yanan, the suspected plague patients admitted by the city's First People's Hospital do not know what the situation is.

What did you want, Gao Fei called, "Director Gu, the suspected plague patient reported by the First People's Hospital of the city has been laboratory confirmed, it is plague." ”

Gu Yanan's heart sank, "Judging from the symptoms, what kind of plague is it?" ”

"Pneumonic plague, the patient is the owner of an antique shop in the city's high-tech zone, but the person has died."

"Dead?!"

"Well, when the person was sent to the hospital, he had already developed multiple organ failures, and he was given medicine, but he was not rescued."

Gu Yanan felt that things were not good, a pneumonic plague patient appeared in the city, and there must have been many people who had been in contact with him, and it was a tedious and urgent task to trace the movements of contacts.

"Investigation ...... of the deceased's contact with people"

Without waiting for Gu Yanan to finish speaking, Gao Fei took the initiative to report the situation over there, "Zhou Lao and I have started the tracing investigation of the contact people of the pneumonic plague deceased, with the help of the disease control of the high-tech zone, things are going well, and it is expected that all the people who have been in contact with the deceased will be traced tomorrow morning." ”

"Okay, feel free to contact us if you have a situation."

After talking to Gao Fei on the phone, Gu Yanan tried to link the pneumonic plague epidemic in Lijia Village, Wangjia Village, Qingcheng Mountain, with the pneumonic plague of the owner of an antique shop in the city.

By all indications, the two have nothing to do with each other,

But the more she couldn't see the connection on the surface, the more suspicious Gu Yanan felt.

Qingcheng County and the city are only more than 100 kilometers apart, and there must be some kind of connection between Qingcheng County and the urban area, and there must be some kind of connection that she has not yet discovered.

Gu Yanan re-compared the information of the two pneumonic plague outbreaks in his mind, and Li Kai, section chief of Qingcheng County Disease Control and Control, hurriedly ran into the temporary emergency headquarters.

"Director Gu, there is news from the village sentry post that Wang Dehua's son has come back from a business trip and has to cross the cordon to go home, and now he is being stopped outside the cordon."

"Wang Dehua's son?"

"Wang Anbang, the nephew of Wang Dequan, the first case, he is the only one left in his family, his parents and relatives are dead, oh, no, his aunt's family also has a cousin who goes to school in other provinces is still alive, and he is also a poor person......"

Section Chief Li sighed, but Gu Yanan immediately thought that Wang Anbang was the nephew of Wang Dequan, the first case, and he should know something about Wang Dequan's situation before his death, and he might know some clues that Wang Dequan was infected with Yersinia pestis.

"Let's go, let's go talk to Wang Anbang."

——

Qingcheng Mountain, Wangjia Village Village Entrance Road, temporary sentry post.

At a makeshift post outside the cordon, there were two heavily armed police officers and two disease control workers, as well as a young man with an anxious look.

The young man looked like he was in his twenties, dressed in a formal work suit, and carrying a suitcase with an airline tag on it.

It seems that it was Wang Anbang, who rushed back as soon as he got off the plane.

Wang Anbang tried to rush through the cordon, but was stopped by two policemen.

Wang Anbang couldn't break through, so he could only look in the direction of his home from afar, crying: "I just want to go home and see, my parents and uncle are in the village, Wangjia Village is my home, why don't you let me go home." ”

"There is a plague outbreak in Wangjia Village, and it has been quarantined, and non-staff are not allowed to enter." A young sentinel officer who was transferred from the county to carry out emergency isolation duties explained.

Wang Anbang was so anxious that he couldn't listen to the explanation at all, "Is there really a plague?" How are my parents? Where's my uncle? I couldn't get through to them, I saw the news on the Internet on the way back from a business trip, saying that there was a plague at home, I didn't expect it to be true, I want to see my parents......"
