Gao Fei took two people from the county disease control to re-sample Xia Youfa's house, and caught as many as possible food, water, soil, domestic pigs, domestic dogs, and rats at home.

Lu Li and Wang Xiaoxiao led three other people from the county disease control to set up a temporary medical tent at the entrance of Xiajia Village, contacted the head of Xiajia Village, and summoned all the villagers to come to the medical tent for physical examination and blood collection, check whether there are symptoms of leptospirosis, and publicize the prevention and control measures of leptospirosis.

Zhou Lao took the county CDC and other people to several villages near Xiajia Village to check whether the villagers had symptoms of leptospiral infection such as fever, bleeding, and jaundice.

Gu Yanan and Gu Qingcen were taken by Li Xiaoju to the orchards and rice fields that Xia Youfa often went to a few days before the onset of the disease.

The rice fields where Xia Youfa made his fortune are located by the river.

There are relatively flat paddy fields on both sides of the wide riverbank, located in a hilly and low-lying area.

Li Xiaoju pointed to one of the paddy fields, "That paddy field is mine." ”

Gu Qingcen put the trap around the rice field, preparing to come over to pick up the captured wild mice when he left in the evening.

Li Xiaoju bypassed the mouse trap and followed Gu Qingcen's side, she had a good impression of this young and handsome young man, and couldn't help but want to say a few more words to him, "Doctor, why do you put so many mouse traps, there are no mice in my rice field, and I usually work here and don't see mice come out." ”

Gu Qingcen was just busy laying out the mouse trap, and did not answer Li Xiaoju's question, and his face did not even change.

Li Xiaoju thought that Gu Qingcen didn't hear it, so she asked again, and Gu Yanan, in order to alleviate the embarrassing atmosphere, replied, "Wild mice have nocturnal habits, basically day and night, which conflicts with our usual labor time, so we don't see mice when we come to work in the field." ”

Li Xiaoju understood at this time that the beauty in front of her was easier to talk than the handsome guy just now, so she followed Gu Yanan's side, "Oh, so my husband's illness is really related to the rats in the field?" ”

"Not necessarily, but it's very likely that we're investigating the source of infection right now."

Soon, the rat traps were arranged around the rice field according to the wild rat trapping procedure, and the next three people were ready to go to the apple orchard where Xia You's family had made his fortune on the hilly slopes.

On the way from the riverside paddy fields to the orchard on the hillside, Lu Li and Wang Xiaoxiao were giving medical check-ups to the villagers, and two police cars were parked at the entrance of the village.

A team of plainclothes policemen got out of the police car, led by people familiar to Gu Yanan.

Nan Hanfei was dressed in casual sportswear, and when he saw the villagers gathered at the entrance of the village, he walked over and planned to ask something.

Gu Yanan didn't expect the police to appear here, and it was the criminal police team to investigate, could it be that someone died? Could it be related to this leptospirosis outbreak?

Gu Yanan turned around and walked towards the medical tent, intending to ask Nan Hanfei for clarification.

Seeing that she had changed direction, Li Xiaoju hurriedly shouted, "Why did you go back to the village?" The orchard is going this way. ”

Gu Yanan: "I have something to ask clearly, you wait a minute. ”

Gu Qingcen noticed from the beginning that Gu Yanan's eyes were always on Nan Hanfei, who had just gotten off the police car, although he knew that Gu Yanan was so active in looking for the past, probably because of work, but Gu Qingcen's eyes still flashed a trace of loss.

After Gu Yanan walked out a few steps, Gu Qingcen followed closely, and Li Xiaoju also followed behind the two of them when he saw this.

Nan Hanfei noticed Gu Yanan who came over in a hurry.

Xiao Li, the policeman who was following Nan Hanfei, began to laugh and quip, "Boss, you are really fated to be with Director Gu of Disease Control and Control, you can meet seven or eight times out of ten cases." ”

Nan Hanfei just smiled and watched Gu Yanan come over.

Gu Yanan was not verbose, and asked directly, "Is there a case?" ”

"Hmm."

"Dead?"

"Hmm."

"Is it related to the leptospirosis outbreak that our CDC investigated this time?"

"It shouldn't matter, the deceased is not from Xiajia Village, and he is not from a nearby village, let alone Chinese, and it should have nothing to do with the epidemic you investigated."

"The deceased was a foreigner?"

Knowing that the deceased might have nothing to do with the epidemic, Gu Yanan couldn't help but ask with curiosity.

Nan Hanfei glanced at Gu Qingcen, who was following Gu Yanan, as well as the surrounding crowd, deliberately took a step closer to Gu Yanan, stretched out his head and whispered in Gu Yanan's ear, "Yesterday, our police team received a report that a corpse was found in the lower reaches of the Burning Xiang River, and the police found that it was a yellow-haired foreigner with a wound on his neck, a carotid artery was cut, and he died of excessive blood loss. ”

After speaking, Nan Hanfei raised his head and took half a step back, his voice became louder, and said to Gu Yanan with a smile, "Yanan, what I just told you is a secret between the two of us, you can't tell others." ”

Gu Yanan knew that what Nan Hanfei just said had involved the content of the criminal case under investigation, and it was indeed inconvenient to say it outside.

"Okay, I won't tell others, then you continue to be busy, and I and the disease control people have to go to the hillside orchard for investigation."

——

10:20 a.m.

Xiajia Village, hilly hillside orchard.

In the apple orchard where Xia Youfa made his fortune, because he had just applied herbicides a few days ago, the weeds in the entire orchard had died and lay flat on the ground.

Gu Qingcen and Gu Yanan set up rat traps and sticky rat boards in and around the orchard.

Li Xiaoju has been very curious since she saw the police car just now, especially when she saw Nan Hanfei intimately saying something in Gu Yanan's ear, it must be a secret, Li Xiaoju couldn't help but ask when she was following Gu Yanan, "Doctor, why are there still police officers here today?" Does it have anything to do with my husband's illness? Or is there something wrong with someone in the village? ”

Li Xiaoju's question was full of gossip.

This time, even Gu Yanan, who has always been enthusiastic, didn't want to answer, but just replied copingly, "It doesn't matter." ”

"Is that a crime committed by someone from the village?"

"I don't know."

Gu Yanan's tone obviously didn't want to continue to answer Li Xiaoju's question, Li Xiaoju also felt it, but she still asked again very gossipy, "The policeman who talked to you just now is your object?" ”

Gu Yanan choked and coughed, but he didn't expect Nan Hanfei to bow his head and whisper in his ear just now, and he was regarded as an intimate action by outsiders.

"Not ......"

Here Gu Yanan was a little bored by Li Xiaoju's question, over there Gu Qingcen had already finished putting the mouse trap in his hand and came to relieve Gu Yanan, he pointed to an apple tree with four or five big apples on the ground next to him, and asked Li Xiaoju, "This apple tree is different from the surrounding fruit trees, it bears fruit and ripens early, what kind of apple is this?" ”

Speaking of his own orchard, Li Xiaoju's attention was immediately diverted, "This is the Gala fruit tree, the Gala apples ripen early, if these apples should have been picked two days ago, isn't this my husband hospitalized, I haven't had time to take care of it, just a few days before my husband was hospitalized, he also said that a big and red Gala fruit fell on the ground, some were gnawed by rabbits, he was reluctant to throw it, and ate a ......"

"Wait!"

Gu Yanan interrupted Li Xiaoju's words and asked, "You just said that Xia You ate the apples that fell on the ground and were gnawed by rabbits before Xia You got sick?" ”
