The leader of the workers in charge of the construction of the exterior wall of the P3 laboratory explained to Director Yang, "In the past, it was because of the wrong operation of the workers that the acetylene gas cylinder was detonated, and a small-scale explosion occurred, and the explosion affected the transformer of the CDC. ”

Director Yang's tone was not good, "Fortunately, there are no major problems in our P3 laboratory, otherwise no one can afford this responsibility." ”

Here, Director Yang discussed the cause of the accident with the construction leader, and Gu Yanan was even more surprised to find that Gu Qingcen had come out of the P3 laboratory.

"You...... How did you get out of the P3 lab? ”

Gu Qingcen's face was indifferent, "When the explosion occurred, I happened to be helping out in the laboratory, and Director Yang knew that I had experience working in the P3 laboratory, so he asked me to go in with my colleagues in the laboratory to check."

Now everything is running normally inside, and because there is a backup power system, none of the bacterial strains in the refrigerator have been affected. ”

When Director Yang saw Gu Qingcen come out, his attention shifted to this side, "How is the situation inside?" ”

"Everything is working fine."

After receiving Gu Qingcen's exact answer, Director Yang's heart relaxed and breathed a sigh of relief, "That's good, now the exterior wall repair work, I will personally keep an eye on it, and your disease control team will continue to deal with this anthrax epidemic." ”

After the episode, the power supply was restored, and colleagues in the laboratory worked overtime overnight to test all the specimens collected from the hospital, the Eastern University Town, the Food Street, and the Yuntai Ranch.

Among the hospital patients, Wang Likun, the rancher, Zhang Yongsheng, the chef of the canteen in the Eastern University Town, the college students who fainted in the canteen, and the blood samples of students who were seroantibody-positive for the first time in the university town, and the blood samples of several workers in the Yuntai Ranch were detected in the blood samples of Bacillus anthracis.

Bacillus anthracis was detected in the mutton at the barbecue stall at the east lane of the food street.

Bacillus anthracis was also detected in sick sheep at Yuntai Ranch and in soil samples collected at each location of Yuntai Ranch.

The laboratory got evidence that it was an anthrax outbreak.

Moreover, the soil of Yuntai Ranch has been contaminated with Bacillus anthracis, forming a natural foci of anthrax.

Gu Yanan took the test report and analyzed in his heart: There were no reports of anthrax cases in Lianhai City before, and the anthrax epidemic in Yuntai Ranch was likely to be related to the goats introduced by the rancher from the northwest, and the source of the goats and the carriage of Bacillus anthracis in the origin of these goats should be traced.

Gu Yanan found the origin of the goats from the information of Yuntai Ranch overnight, and contacted the local CDC to assist in investigating the contamination of Bacillus anthracis in the goat's production area.

Early in the morning of the second day, Gu Yanan and the members of the emergency team went to Yuntai Mountain Ranch with a large amount of disinfectant, preparing to disinfect the entire pasture soil.

There are still police guards at the highway checkpoint under the mountain, but the guards have changed a wave, and Nan Hanfei has not been seen.

After the highway checkpoint, the emergency team carried a large amount of disinfectant to the mountain, and the people of the animal husbandry department at the foot of the mountain have finished culling the sheep in the entire Yuntai pasture, and dug a very large long pit at the foot of the mountain to harmlessly destroy the culled sheep.

Soon, the pungent smell of the disinfectant overshadowed the bloody smell of culling goats.

For a whole day, the disinfectant was sprayed.

When the smell of disinfecting soil permeated the entire Yuntai Ranch, Gu Yanan's mobile phone rang.

The caller ID is the number of the Northwest goat's CDC.

The local CDC has reviewed the data and conducted a field investigation in the goat's production area, which is a natural foci of anthrax and Bacillus anthracis has been detected in the soil of the local pasture.

Moreover, there had been a case of anthrax in sheep at that ranch two months earlier.

Lianhai Center for Disease Control and Prevention, Emergency Office.

More than two weeks have passed since the anthrax outbreak was discovered at Yuntai Ranch.

Except for Wang Likun, the rancher of Yuntai Ranch, who died due to sepsis complicated by multiple organ failure, and the rescue was ineffective, other patients infected with anthrax were successfully discharged.

The sick mutton sold from Yuntai Ranch has also been recovered one after another, and there have been no new cases in two weeks.

The quarantine in the epidemic area in the university town of the Eastern District has also been lifted, and the school has resumed normal teaching order.

The emergency response to the anthrax outbreak ended and the outbreak was brought under control.

Gu Yanan writes a summary report of the anthrax outbreak in the emergency office.

Wang Likun, the owner of Yuntai Ranch, bought a batch of goats from the northwest, which carried Bacillus anthracis, and after entering Yuntai Ranch, the sheep began to become ill and contaminated the entire pasture with Bacillus anthracis.

The original sheep in Yuntai Ranch were also infected one after another.

The rancher ordered the rancher workers to slaughter the sick sheep and sell the meat to different customers.

During the slaughter of sick sheep, ranchers and ranchers were infected with Bacillus anthracis.

Sick mutton was purchased from the University Town Canteen in the Eastern District, and the chef, Zhang Yongsheng, was infected while handling the mutton, causing cutaneous anthrax.

The barbecue stall at the east lane of the food street in the university town also bought sick mutton and made a lamb skewer, and the college student Li and others were infected by Bacillus anthracis in the process of eating, causing intestinal anthrax.

After the anthrax cases were discovered, timely measures were taken to cut off the transmission route, eliminate the source of infection, recover the sick mutton, and the epidemic was controlled.

Gu Yanan lowered his head and wrote a summary report on the epidemic, and the doorman of the CDC came up to deliver letters as before, one of which was placed on Gu Qingcen's desk.

A very ordinary envelope, with "Gu Qingcen received" printed on the computer, it seems that it should be an official letter.

Gu Qingcen tore open the envelope casually, and a folded white paper fell out of it, and a lot of white powder was scattered from the white paper.

A breeze blew through the window, blowing the white powder into the nostrils and wafting into the nostrils, with a faint smell of milk.

There was a bang in Gu Qingcen's head, he realized something, and was about to stand up when the mobile phone next to him rang.

The caller ID is a string of numbers, which is very familiar.

Suppressing the anger in his heart, Gu Qingcen picked up the phone.

A familiar and annoying voice came from his phone, "Gu, do you like the gift I gave you?" This time it's just milk powder, and if you don't make any progress, you won't know what will be added to the milk powder next time. ”

Gu Qingcen was silent.

The voice on the phone continued, "Gu, the injury on my neck has healed, thank you for your mercy last time, but I still like your cold appearance, the way you are cold to everyone."

Gu, remember our agreement, otherwise I will continue to help you, and helping again will not be as simple as the previous blister snail and today's milk powder.

Dear Gu, don't forget our common great ideals, waiting for your good news. ”

Gu Qingcen continued to be silent, and the other party took the initiative to hang up the phone.

After Gu Yanan finished writing the summary report of the epidemic, he raised his head and found that Gu Qingcen had put down the phone and his face was not good.

Gu Yanan asked, "Brother Qingcen, what's wrong?" ”

Gu Qingcen quickly regained his usual warm smile, "It's okay, call to advertise, oh, by the way, Yanan, I have to take a leave of absence for the next two weeks." ”

"Leave? Do? Gu Yanan was inexplicably a little nervous.

"I had something to do at the Médecins Sans Frontières office before, so I'll go back and hand it over this time."

"Are you coming back?" Gu Yanan asked in a low voice.

"Of course, I'm just taking a leave of absence and will be back soon."
