"That's right, after Wang Lele was bitten by a dog, Grandma Wang used the frog skin of the frog dug up from here to apply a wound to him, which may be a very important route of infection, we need to confirm."

Lu Li also found a shovel and went down to the pond to dig frogs.

Wang Xiaoxiao stood by the pond, guarding the sampling box, holding the sampling bag, ready to collect the frogs dug up by the two.

After the Spring Festival, the weather warmed up, and the silt under the grass by the pond was soft, so Lu Li found a place, dug a few times with a shovel, and dug a frog out of the mud.

The frog was motionless, as if dead, but reaching out to touch, its body was soft, just hibernating.

Lu Li threw the frog ashore, Wang Xiaoxiao took over, sealed it with a sampling bag, and put it in the sampling box.

After a while, Lu Li and Gu Yanan dug up 7 frogs in different corners of the pond.

"Sister Yanan, there are already 7 frogs, which is representative." Wang Xiaoxiao shouted on the shore.

According to the sampling standard, it is already possible to dig 7 frogs, and Lu Li and Gu Yanan went ashore.

After taking off his mud-stained shoe covers and gloves, and just as he sat back in the car and was about to return to the CDC, the phone in Gu Yanan's pocket rang urgently.

Picking up the phone, Nan Hanfei's slightly anxious voice came from inside, "Yanan, something happened." ”

Gu Yanan's heart tightened, listening to Nan Hanfei's tone, could it be that there was something big going on? Or is it a big case related to yourself?

"What's the matter?"

"Gu's mother came to the police station to give me dumplings just now, I didn't notice it, I was talking to a colleague, one of my colleagues talked about the last time you were kidnapped by a prisoner in the detention center, and also said that I was your fake boyfriend, this happened to be heard by Gu's mother, she questioned me, I found a reason to prevaricate, but she obviously didn't believe it, I guess I will go back and ask you, I will report to you here first."

Sure enough, it's a big deal, and this is the rhythm of revealing the stuffing.

In case the relationship with Nan Hanfei is a fake boyfriend and girlfriend is known by the mother, the mother's temper must be a storm, and then there are countless blind dates.

Just thinking about it, Gu Yanan felt a headache.

"What's the reason you're telling my mom? I'm going to go on with it. ”

"I told Gu's mother, it was just an expedient measure for me to persuade the robbers, I didn't want the robbers to embarrass you, and I didn't say more, after all, this kind of thing is said to be wrong, and the reason I just said was indeed the purpose at that time."

"Okay, I know, you just have to stick to this reason, and I'll take care of the rest."

——

Lianhai City Center for Disease Control and Prevention, gate.

Gu Yanan drove the on-site flow shunting car and rushed back from Wangjia Village.

I met a familiar figure at the gate.

Gu's mother stood at the gate of the CDC to block the way of the shunting car.

Gu Yanan's heart was not good, and her mother actually came to the door of the unit to block people.

Gu Yanan stopped the car, but did not get out of the car, just rolled down the window.

Gu's mother was full of anger, and spoke to Gu Yanan through the rolled down window, "Gu Yanan, do you want to explain something to me." ”

Every time Gu's mother called her by her name and surname, she must be angry, and very angry.

"Mom, what do you say? It's work time, and I'm still in a hurry to get back to the lab. ”

"Don't pretend to be confused with your mother, what's going on with you and Xiaofei?"

Gu Yanan deliberately pretended to be confused, "I'm on good terms with Nan Hanfei, it's fine." ”

"Are you alright? I just came from the police station, and I've heard about you in the detention center, are you just looking for someone to be your boyfriend to fool your mother? ”

Gu Yanan tried to make an innocent appearance to defend himself, "No, Mom, you must be mistaken, when I was in the detention center, Nan Hanfei only said that to stabilize the robbers, in fact, we have always been very good." ”

Gu's mother sneered, "Continue to make up, you have already colluded with Xiaofei to make a confession, right?" Your mom and I are not stupid, I called your brother just now, and he said everything. ”

Gu Yanan chuckled in her heart, forgetting about her brother, but according to her brother's temper, she would definitely not betray her, could it be that her mother used some trick to break through her brother's tone?

No matter what happened, it turned out to be exposed.

"Mom, I can explain this matter to you, but not now, there is a very important patient to do the abortion investigation, hurry up, go first."

Gu Yanan rolled up the window, stepped on the accelerator, and drove the shunting car into the CDC compound.

Work is important, Gu Yanan put down the fact that his mother found out that he was pretending to be a boyfriend, and entered the laboratory first to test the samples collected from Wang Lele's house in Wangjia Village one by one.

Under the microscope, jaw nematodes were found in 7 hibernating frogs.

The big yellow dog that was killed by Lele's father was not found in the jaw mouth nematode, and the big yellow dog was not the source of infection, it was wronged.

The way Wang Lele was infected with jaw nematode is already clear.

The frogs in the pond in the backyard of Grandma Wang's house are the intermediate hosts of the jaw nematode.

Wang Lele was bitten by his own big yellow dog before the Spring Festival, and Grandma Wang dug out the frog infected with the jaw nematode from the pond and applied the frog skin to the wound, and the jaw nematode entered Wang Lele's body from the frog's body through the wound, violating Wang Lele's heart, brain, kidneys, eyes and other organs, causing a series of symptoms.

This rare epidemiological investigation into human infection with jaw nematode has ended.

Wang Lele was also discharged from the hospital after finding the cause and treating it in time.

After the work matters are dealt with, Gu Yanan has to start dealing with the personal matters that give her a headache.

Before going home to face her mother, Gu Yanan first went to the hospital to find her brother Gu Jiashu.

——

Lianhai First People's Hospital, Department of Infectious Diseases.

Gu Jiashu has a night shift at night, and Gu Yanan directly finds his brother Gu Jiashu's office after getting off work in the afternoon.

"Brother, I believe you so much, how can you tell my mother the secret between me and Nan Hanfei?" Gu Yanan's face was full of grievance and anger.

Gu Jiashu was questioned by the younger sister and also felt aggrieved, "It was my mother who cheated, she came directly to my office that day and told me that she had just come from the police station, Nan Hanfei told her everything, saying that it was your idea to let Nan Hanfei pretend to be your boyfriend, I thought it was true, so I confessed everything I knew." ”

Sure enough, it was my mother who cheated me.

For his brother Gu Jiashu, Gu Yanan couldn't bear to complain, so he could only find a way to deal with his mother's next storm.

Standing in front of Gu Jiashu's desk, Gu Yanan suddenly fell silent.

Frightened by the sudden silence of the little sister, Gu Jiashu hurriedly comforted, "Little sister, even if it is known by my mother, it is not a big deal, at most I will be scolded, it is a big deal that I will accompany you home to be scolded, so that I can also divert my mother's attention a little." ”

Gu Yanan sighed, "It's only like this, my brother is still good to me, but even if I want to be scolded, it will take a few days." ”

"Why? The later you get home, the angrier your mom will become. ”

Gu Yanan took out an invitation to an academic conference, "There is an academic conference, it takes a week, I didn't want to go, but now I suddenly feel that it is better to go, brother, I will trouble you to say more good things to me in front of my mother in the past few days, I hope that when I come back, her anger will disappear." ”

Gu Jiashu helplessly held his forehead with his hand, "Go ahead, let me bear the storm alone, who made me your brother." ”
