The villagers who were notified last night gathered around the cemetery early in the morning, and they were all concerned with the families of the deceased.

The families of the deceased prepared offerings and made a memorial service before digging up the grave and collecting the body.

The staff of the investigation team waited for the family of the deceased to pay their respects before they began to disperse the crowd of onlookers and set up a simple cordon around the cemetery.

The graves of the deceased in the six cases of burial are not far apart, but they are connected together, and the area of the warning belt is still very large.

Workers dressed in protective clothing dug up the bodies that had been buried one by one.

The deceased had been buried for several days, and the body began to decompose, and the body exhumed from the ground emitted a foul smell.

Nan Zhiqiao looked at Zhen Zhen, worried that she couldn't stand such a pungent smell of corpses in the plateau climate, and asked with concern, "Is it okay?"

"Yes, let's get started. ”

The six corpses were decomposed to varying degrees, and two were wearing protective suits, which could block bacteria and other microorganisms, but the smell of the corpses could still penetrate through the high-efficiency filter and into the nostrils.

The first was the body of Dolma, who was the first deceased to die and be buried besides the village doctor Tenzin.

Dolma was the first to be buried, and the corpse was the most severely decomposed, and the internal organs had begun to melt.

Zhen Zhen took a scalpel, dissected the skin and muscle tissue, and took the liver, spleen, lungs, heart blood, lymph nodes, and tissue samples of various organs and tissues into sampling tubes for preservation.

The remaining five corpses were lightly decomposed, but the appearance of the corpses was even more terrifying.

In the early days, plague patients were also called "Black Death", when the patients died, their whole body was black and purple, and the seven orifices bled out, which was in line with people's most terrifying imagination of epidemic death.

The degree of decomposition of the corpse was light, and the sampling was simpler, and the liver, spleen, lungs, heart and blood, as well as lymph nodes with suspicious changes were also taken, loaded into sampling tubes, and clearly marked.

After the collection of specimens from all deceased patients, the specimens were uniformly loaded into the sampling box and escorted by full-time personnel to the laboratory of the Autonomous Region Center for Disease Control and Prevention for confirmatory testing of Yersinia pestis.

After the sampling, the corpses were changed from burial to cremation, and the corpses were incinerated, blocking the possibility of further transmission of the epidemic.

The environment around the original burial has also been strictly disinfected.

Taking into account the customs of the local people, after the body was burned, the investigation team agreed that the villagers invited several lamas to perform a ritual on the deceased.

During the ceremony, with permission, the family members of the deceased arrived at the scene, Ye Zhenzhen had never seen such a scene before, and stood curiously not far away.

Lao Zhao and Dorjee were in charge of the families of the deceased, because during the epidemic, gatherings were prohibited, so when the ceremony was held, the families of the deceased could only watch from a distance.

Nan Zhiqiao has seen this kind of scene before, and it is a custom of Tibetan Buddhism to ask lamas to perform funerals.

Ye Zhenzhen first watched the lamas do the work, and then was attracted by the families of the deceased.

While the lamas performed their services, the families of the deceased knelt and prayed reverently in the distance.

Zhen Zhen's eyes swept over the sad faces, these people had all seen them when they were sampling yesterday, and they all had an impression.

Suddenly, Zhen Zhen's aimless eyes turned into a state of searching, and after looking in the crowd twice, Zhen Zhen approached Nan Zhiqiao's ear beside her and asked in a low voice: "Senior Nan, have you noticed that there is one person missing from the family." ”

Nan Zhiqiao: "There are not a few family members of the six deceased, and the relatives are far away and close, so they won't all come to participate, which one are you referring to?"

"Dawa's husband, Nima, this is his wife's funeral, why didn't he come to attend?

Nan Zhiqiao was also aware of the seriousness of the problem, when he saw Nima yesterday, he found that his face was bruised, and he already had the initial symptoms of the disease, and he quickly diagnosed on the spot, and Nima was positive for the plague bacillus in his body, and Nima couldn't get out of bed because he was sick.

Nan Zhiqiao and Zhen Zhen find Dawa's house.

There are still 6 people in Dawa's family, Dawa's father, mother, eldest sister, eldest sister, younger sister, and Dawa's husband, Nima.

In addition to Nima, Dawa's other family members are there.

Nan Zhiqiao asked about Nima's whereabouts, and Dawa's family was at a loss to get to the point.

Intuition tells Zhen Zhen that Nima's situation must be as simple as being sick.

What worries Nan Zhiqiao and Zhen Zhen most now is whether Nima has left the village, and if so, where has he gone, and who will they meet along the way?

If a plague-positive patient leaves the quarantine without permission, the epidemic will spread, and the consequences will be serious.

Zhen Zhen sought out Dorjee, who was more familiar with the villagers, and voiced her worries.

Under Dorjee's questioning, Dawa and Nima's family finally revealed Nima's whereabouts.

It turned out that after the investigation team finished collecting samples at Nima's house yesterday afternoon, Nima heard that the out-of-town tourists who had lived in his tent had died of illness, and Nima, who was already in shock, became even more frightened.

After the investigation team left, Nima felt a severe headache, and her cough worsened and she coughed up bloody sputum, which was the same as the symptoms of his wife Dawa before her death.

Nima was terrified and did not believe that the investigation team would be able to cure him.

Nima wants to leave the village and go to the county hospital for treatment.

Before the investigation team's diagnosis came out, Nima took advantage of the moonlight to secretly leave M Village.

Because the investigation team had previously informed the villagers that Village M was classified as a quarantine circle, the villagers could not gather at will, let alone leave without permission.

Therefore, when Nima left, she only told her own family.

Although Village M was classified as a quarantine circle, due to the lack of manpower in the investigation team, the effect of isolation depended on the villagers' consciousness and the supervision of the village committee.

Knowing these details, Nima found the gap between the investigation team and the village committee's patrol, and rode away quietly.

Dorjee asked about Nima's specific whereabouts, and Dawa's father confessed that when Nima left, he only said that he was going to the county hospital to see a doctor, and as for which route to take, except for Nima, no one else was clear.

Dorjee couldn't ask for more clues, and if he sent someone to chase Nyima now, it would be too late, so he could only take remedial measures to control the epidemic.

Dorjee sent people back to the county seat of L and made a detailed report on the situation in Village M.

After receiving the report of the epidemic from the staff who returned from the scene, the L County Health Bureau quickly issued an emergency notice to the county's medical institutions: strengthen the monitoring of all fever patients, and once a patient from M village is found, immediately isolate and report to the county CDC to prevent the further spread of the epidemic.

——

After Dorjee's emergency response to Nima's failure to quarantine as required and her unauthorized escape, in the afternoon of the same day, the investigation team in M Village received the first batch of test reports from the Autonomous Region Center for Disease Control and Prevention.

The test samples in this batch of test reports are the first batch of samples sent by the investigation team for testing, including the villagers of Village M, as well as some sampling specimens of domestic animals at the scene.

Among the 15 patients, in addition to 7 who had died, among the remaining 8 patients, Y. pestis was isolated from the sputum of 1 case, and 7 cases had two times increased serum antibody titers more than 4 times, which could confirm the diagnosis of pneumonic plague patients.
