Exiting the balcony, Lu Li entered another large south-facing bedroom.

This is Grandpa and Grandma Li's bedroom, with a large double bed with neat bedding on the bed, a row of wardrobes next to the bed, and a dressing table opposite the wardrobe.

Simple and neat bedrooms, nothing suspicious.

In the end, Lu Li and Xiao Chu went to the kitchen to the north.

As soon as I entered the kitchen, a smell of oil smoke mixed with the smell of Chinese medicine came to my face.

The kitchen is small, cupboards, stoves and range hoods take up most of the space, and although the pots and pans are neatly arranged, Lu Li still feels like he can get off his feet, but he can't turn around.

There is a refrigerator on one side.

"Grandpa Li, I want to see what's in the refrigerator."

Grandpa Li hurriedly opened the refrigerator door.

On the top floor of the refrigerator are leftovers, as well as fruits and vegetables bought.

Below the refrigerator is the freezer compartment, which freezes a piece of pork, two fish, a broiler chicken, and some quick-frozen dumplings.

Lu Li set his sights on pork and broilers.

Raw livestock and poultry meat can also spread the disease.

"Where do you buy pork and chicken? When did you buy it? Lu Li asked Grandpa Li.

"It's all discounted in supermarkets, and last weekend there was an event in a nearby supermarket, and half of the pork was eaten, and the chicken didn't have time to eat it."

Last weekend? The onset time was very close to that of the two patients.

"I'm going to take this pork and this chicken back for testing, is that okay?"

"My two grandchildren's illnesses are related to these pork and chicken?" Grandpa Li asked in surprise.

"I'm not sure yet, so I'm going to take it back for testing."

"Okay, take it all, you can take whatever you want, it doesn't matter if you move the entire refrigerator." Grandpa Li was very cooperative.

Lu Li and Xiao Chu put the pork and chicken in the refrigerator into a sampling bag and put them in the sampling box.

Just as he was about to exit the kitchen, Lu Li found a gray piece of paper in the trash can next to the kitchen door, which was stained with some powder.

Lu Li leaned over, picked up the paper with gloves on, the powder drifted away, and the smell of medicine rushed to his nostrils.

"What is this?" Lu Li asked Grandpa Li.

"Traditional Chinese medicine, Chinese medicine from the Hua's medical hall next door, recently my two grandsons have a cold, the health has not been very good, after the fever subsided, his grandmother wanted to go to the hospital to let the old Chinese medicine to adjust the body, just ate for three days, at first I felt good, and then somehow suddenly the symptoms worsened and I was admitted to the hospital, there are still a lot of Chinese medicine left, and there are 4 days of supply at home."

As he spoke, Grandpa Li took out a package from the drawer under the kitchen cupboard and opened it, revealing a medicine bag wrapped in gray paper.

The medicine bag is very small, unlike the Chinese herbs that you usually grab from the hospital.

Lu Li touched it, and it looked like powder, and asked, "Is this Chinese medicine?" How can the amount be so small? ”

"The old doctor said that this is Chinese patent medicine."

Lu Li also often takes Chinese patent medicines, but they are all finished products, and they can be bought directly in pharmacies, such as the most commonly drunk banlan root powder, all kinds of cold spirit powder, like this kind of Chinese patent medicine wrapped in private paper, I have never seen it.

Before coming to the scene, Gu Yanan had instructed not to let go of all the details, although Li Tianyi and Li Tianming suspected that it was viral encephalitis, but they did not rule out other possibilities.

The time when the two patients took Chinese medicine was very similar to the onset time of this unexplained encephalitis, and the possibility of correlation could not be ruled out, so Lu Li decided to bring back all the suspicious specimens.

The specimen was brought back to the CDC laboratory, and Section Chief Li looked at the various external environmental specimens in addition to the patient's body fluids, and frowned together, "I can still understand the external environmental specimens of pork and chicken, what is this?" Proprietary Chinese medicine? What should be done to test the microbiome when Chinese patent medicine is used? ”

Lu Li smiled, "Our Director Gu should have communicated with you, all specimens are tested for encephalitis-related viruses, don't run out of specimens, maybe there will be other tests in the future." ”

Section Chief Li sighed, "Didn't I pour cold water on your emergency team, no encephalitis-related viruses were detected in the patient's body fluid samples, so what's the point of testing the external environmental samples?" ”

"The patient has already used drugs before, and the test of the patient's body fluids may have false negative results, and now the external environmental samples are screened again, and there may be findings, and we will continue to follow up on the patient's situation."

"Okay, the epidemic is the sky, the emergency team is the earth, and our laboratory is your ladder."

After leaving the laboratory, it was almost time for the video conference, and several members of the emergency team met to briefly discuss the situation of Li Tianyi and Li Tianming, and then went to the video conference room of the comprehensive office building.

Video conference room.

Personnel from several relevant departments of the CDC were all present.

More than 20 people sat at the meeting, staring at the video screen in front of them.

There is a large headline on the screen "2019 Novel Coronavirus Pneumonia Prevention and Control Training Video Conference".

At the beginning of the video conference, several relevant leaders of the National Health and Family Planning Commission and the National Disease Control and Prevention made speeches, followed by experts from the National Disease Control and Prevention to introduce the new coronavirus.

Wang Xiaoxiao saw one of the experts and began to whisper to Lu Li beside him, "Isn't the most handsome expert in the video Nan Zhiqiao?" I came to our Lianhai CDC during the investigation of the contamination of baby powder, and I was very impressed with him. ”

"You're very impressed with handsome men." Lu Li pouted.

"No, mainly because Nan Zhiqiao is Nan Hanfei's cousin."

"Officer Nan and his cousin work in the national disease control? How did I not know? Where did you hear about it? ”

"I'm well-informed, and I mentioned it when I heard Sister Yanan talk on the phone by chance."

Wang Xiaoxiao and Lu Li were talking a little loudly, Gu Yanan glanced at the two of them, and the two immediately stopped talking.

The PPT on the video screen kept changing, and several of the 2019 new coronavirus gene sequence diagrams and genetic evolution tree diagrams appeared.

Xiao Chu looked at it carefully, and discussed with Gu Yanan in a low voice, "The genetic sequence of the 2019 new coronavirus is still very different from the previous sequence of the 2003 SARS coronavirus, and it has a higher homology with a strain of coronavirus in bats. ”

Gu Yanan: "But this doesn't explain anything, the genetic similarity of the virus cannot be equated with the similarity of the pathogenic ability of the virus, although the new coronavirus discovered this time belongs to the same family of coronaviruses as SARS and MERS coronaviruses, but genetic evolutionary analysis shows that they belong to different subgroups and branches. It is neither SARS nor MERS viruses, and their viral genetic sequences are quite different enough to form a new subpopulation. ”

Xiao Chu nodded slightly in agreement.

The PPT on the video screen continued to change, and after talking about the genetic sequence and pathogenicity of the new coronavirus, he then talked about the problems that should be paid attention to in on-site flow investigation and laboratory testing, especially when it came to personal protection.
