11 p.m.

The western suburbs of Lianhai City, the home of cute pets.

Gu Yanan, Zhou Lao's group of disease control and control, and Nan Hanfei who came with him stood at the door of the pet store.

The pet store is a self-built two-story small building with a large yard and a large iron gate outside the yard, the iron gate is closed, there is no light in the small building, and it is dark.

At this point in time, the owner of the pet store should have fallen asleep.

Gu Yanan knocked on the door, but no one responded for a long time.

Zhou Lao asked, "We knocked on the door for so long, and the sound was very loud, they should have gotten up, it can't be that there is no one in the store, right?" ”

Zhou Lao also knocked on the door vigorously, and suddenly a figure appeared in the door of the neighbor's house next door.

"Hey, don't knock, there's no one in that store."

It was a middle-aged woman in her 40s who spoke.

Finally came out and knew the situation.

Zhou Lao greeted him and asked, "Do you know where the owner of the cute pet house went?" ”

"Sick, both husband and wife are sick, hospitalized, the worker they hired was sick two days ago, when the couple was sick, no one in their store took care of them, and in the morning they asked me to feed and feed your pets.

What's wrong? What are you looking for him and his wife? If you want to buy a pet, you can't come so late, come back in two days. ”

The middle-aged woman couldn't help but yawn after speaking, obviously she had just been woken up, and after saying a few words, she was ready to go back to the house and continue sleeping.

The pet shop owner and his wife are also sick, which is not a good sign, Gu Yanan stopped the middle-aged woman and asked, "What is the name of this pet shop owner?" ”

"The boss's name is Zhang Feng, and his wife's name is Li Mei."

The names Zhang Feng and Li Mei are very familiar to Gu Yanan, and they are in the list of suspected chickenpox patients provided by Wang Xiaoxiao.

Gu Yanan: "Since you have been entrusted with taking care of the animals in the pet store, there must be a key to this house, please open the door, we will inspect the inside." ”

Gu Yanan showed her work card, and the middle-aged woman immediately panicked when she saw that it was from the CDC, she also knew that the news circulating on the Internet said that there was a smallpox epidemic in Lianhai City, and the CDC suddenly appeared at the door of her house so late, could it be that there was an epidemic here?

The middle-aged woman took a step back, and through the dim street lamp, she could see that there was a flow truck marked with the CDC logo behind the group.

Sure enough, it's from the CDC, and the battle is still very big.

The middle-aged woman immediately agreed, went back to the house to get the key, and opened the door of the cute pet house.

Gu Yanan and his party put on protective clothing and prepared to go inside for inspection and sampling, and the middle-aged woman also wanted to go in to see what was going on, but was stopped at the door by Gu Yanan.

"You can't go in, it's dangerous inside, have you come in and touched animals before?"

The middle-aged woman nodded blankly, "Yes, I just fed the animals inside with food and water in the evening, what's wrong?" Questions? ”

"Wait a while, I'll ask the people from the disease control to take a sample for you, that is, take a blood and take a nasopharyngeal swab, don't worry, if you have a fever or feel unwell in the near future, go to the hospital in time, and, this cute pet home, you don't come in recently."

Gu Yanan said that she should not worry, the more scared the middle-aged woman felt, could it be that she was also infected with some serious infectious disease? It can't be smallpox as it says on the Internet, right?

The middle-aged woman originally felt that her body was fine, but when Gu Yanan said this, she also seemed to feel uncomfortable, and decided to go to the hospital for an examination as soon as it was dawn.

Inside the home of a cute pet.

There are several cute cats and dogs in the animal display area on the first floor, and the CDC team checked in the backyard and found that there are more animal species in the back warehouse, with all kinds of marmots, small squirrels, and rabbits distributed in various warehouses.

I looked around, but I didn't see a monkey.

Gu Yanan: "Rodents such as marmots and small squirrels are the focus of our sampling. ”

After inspecting the cute pet home, Gu Yanan pulled up a cordon around the cute pet home again, and made a warning sign that the biological hazard should not be approached.

At 1 o'clock in the morning, Gu Yanan and his party left the cute pet home and returned to the CDC.

——

At 3 a.m., Lianhai City Center for Disease Control and Prevention Laboratory.

The test results of specimens of suspected chickenpox cases collected by the CDC in various counties and districts have come out, and the varicella virus test is negative.

The deceased Qian Jianguo, who Gu Yanan brought back from Hongshan Village, and the animal and environmental samples collected from the cute pet home were also sent to the CDC and were being tested overnight.

Section Chief Li of the laboratory has continuously urged manufacturers that the test kits for detecting monkeypox virus and smallpox virus are being delivered to the laboratory as soon as possible by air, and it is expected to be delivered before dawn under continuous urging.

While waiting for the laboratory test results, Gu Yanan led the team to conduct on-site investigations, and now the focus is on Zhang Feng and Li Ju, the owners of the cute pet home.

After investigation, it was found that Zhang Feng and Li Ju are now hospitalized in the Department of Infectious Diseases of the First People's Hospital.

——

At 5 a.m. on the second day, it was just dawning.

Gu Jiashu received a report from the doctor Xiao Zhang, urgently ended the academic conference in the field, rushed back by plane, just got off the plane, and rushed directly to the hospital with his suitcase.

On the way back to the hospital, Gu Jiashu first contacted the doctor Xiao Zhang and asked about the situation of the inpatients, knowing that since Li Yixuan, there have been many patients with similar symptoms transferred from various hospitals in the city, and they are uniformly arranged in the isolation ward of the infection department, and the CDC has intervened in the investigation, so after talking to the doctor Xiao Zhang, he dialed his sister Gu Yanan's mobile phone.

"Little sister, has the pathogen that infected Li Yixuan been confirmed?"

"Not yet, I'll have to wait another two hours, brother, where are you now?"

"Just got off the plane and went to the hospital right away, what about you?"

"I'm in the infectious disease department of your hospital, asking the patient about some ...... situation."

While speaking, Gu Jiashu had already walked to the gate of the People's Hospital with his suitcase, and suddenly a figure rushed over and collided with him, Gu Jiashu's feet were unstable, and his mobile phone fell to the ground.

When he barely stood firm, Gu Jiashu found that the person who hit him was a woman, although it was more than 5 o'clock in the morning and the sun had not risen, but this woman was wearing a pair of wide sunglasses to cover half of her face.

The woman looked in a hurry, and when she saw that she had bumped into someone, she immediately picked up the mobile phone on the ground, returned it to Gu Jiashu, and apologized again and again, "I'm sorry, I was in a hurry just now, I'm really sorry." ”

After the woman apologized, she left in a hurry without waiting for Gu Jiashu to respond.

Gu Jiashu just felt that the woman just now was very familiar, but he couldn't remember where he had seen it for a while.

The woman hurriedly ran into the hospital, Gu Jiashu stared at the direction the woman left, and was stunned for two seconds before she remembered that she was talking to her little sister on the phone.

"Brother, what happened just now? I heard the sound of my phone falling to the ground. ”

"It's okay, I was bumped by someone just now, and my phone accidentally fell to the ground, and now it's fine. Continuing with the topic just now, although the test results from your CDC have not come out, there should be a suspicion, what do you think the pathogen may be? It shouldn't be smallpox uploaded on the Internet. ”
