The chicken coop is very simple, it is a simple shed made of several bamboo poles, the bamboo poles are directly fixed with ropes, and the outer layer is covered with a nylon net.

There are a dozen chickens in the coop, scrambling for food in the trough.

Next to the chicken coop is a grass shed with weeds such as corn stalks.

There were a few conspicuous dark red spots in the weeds, and Gu Yanan approached and smelled a smell of blood, which was sure to be bloodstains.

Not far from the bloodstain was a half-dried pile of viscous liquid, like vomit.

Gu Yanan pointed to the blood stains in the hay and asked Li Erzhu's daughter-in-law Jin Zhi, who was standing aside, "How did you get these blood stains?" ”

There was still fear in Jin Zhi's voice, "It's the blood of the dead cattle thief, and there are things he vomited out next to it, it's really unlucky, how can a good person die?" We didn't beat him much......"

Before Jin Zhi finished speaking, he was stopped by his mother-in-law next to him.

The mother-in-law answered, "We didn't beat him, he came to steal my cow and poisoned my big yellow dog, we just tied him up and let his brother go home to get the ransom, and the next day he had a fever, he should have died of his own illness, it has nothing to do with us." ”

Hearing the word "fever", Gu Yanan immediately thought that Li Guoqing next door was infected with H7N9 avian flu, could this dead cattle thief also be infected with the avian flu virus?

If so, then those who have come into contact with him are in danger.

Gu Yanan immediately thought of Nan Hanfei, who had just left.

took out his mobile phone and dialed Nan Hanfei's phone, "The body of the cattle thief who was transported by you may be infected with the H7N9 avian influenza virus, you should pay attention to your own protection." ”

Nan Hanfei on the other end of the phone was stunned for a second, but then reacted and said, "Okay, I know, I will let our people take good precautions and let the forensic doctor confirm it." ”

The voices around Nan Hanfei were a little noisy, and the phone was in a hurry, as if he was dealing with something.

Gu Yanan still had some things too late to ask, thinking to himself, to confirm whether it was H7N9 avian influenza virus infection, a very professional test kit was needed, and their forensic department should not have a reagent stockpile, and it was estimated that the specimen would have to be sent to the CDC.

But Nan Hanfei has already left, so he doesn't care about the forensic doctor's side for now, what Gu Yanan has to do now is to investigate the epidemiology around Li Guoqing's house clearly.

Since it is an avian influenza virus, the first thing to check is poultry such as chickens and ducks.

Gu Yanan opened the sampling box and prepared to collect some chicken manure and environmental samples in the chicken coop.

Suddenly, a dark shadow fell from the sky.

The black shadow flapped its wings and stopped by the chicken coop.

It turned out to be a passing wild migratory bird that came down from the sky to find something to eat by the chicken coop.

Wild migratory birds appear to be hungry, with their heads down, pecking at the rice grains scattered on the ground.

Jin Zhi, Li Erzhu's daughter-in-law, who had been standing aside, saw Gu Yanan staring at the falling migratory birds, and explained: "Our home is close to the Crescent Lake Scenic Area, and wild birds often come to look for food. ”

The golden branch shouted loudly, and the wild migratory birds that were eating were frightened away.

Gu Yanan looked up at the direction in which the wild migratory birds flew away, and frowned slightly.

Soon, Gu Yanan retracted his gaze and continued to sample in the chicken coop.

In the process, Gu Yanan found that the chickens in the chicken coop were not in good condition, and a few of them were hanging their heads and curled up in the corner, obviously sick.

"When did these chickens start getting sick?" Gu Yanan pointed to the sick chicken curled up in the corner and asked the golden branch outside the chicken coop.

"Half a month ago, there were chickens that began to get sick, at the beginning there were one or two, and I didn't care at the time, and then there were passing wild birds that died in the yard, my mother-in-law felt unlucky, and took out the dead birds and buried them by the crescent lake, and the sick chickens were plucked and cooked by us."

Gu Yanan's brows furrowed again, Lu Li couldn't help it, and said, "How can you eat a sick chicken?" That's contagious. ”

Jin Zhi was a little scared, "I've been cooking for a long time, and any germs will be killed." ”

"The germs in cooked chicken will be killed, but when you are handling chickens, for example, killing chickens, plucking chickens, chopping chickens into pieces, these times are direct contact with raw chicken, and there is a great chance of infection, and where are the processed chicken feathers and internal organs?"

Jin Zhi's voice became quieter, "When the garbage is thrown away." ”

"Where's the garbage?"

"The garbage can at the head of the village."

"Where's the chicken?"

"It's all eaten."

After Gu Yanan finished collecting samples and was about to go out with the sampling box, Jin Zhi thought that Gu Yanan and Lu Li were going to the garbage can at the head of the village to look for the chicken feathers and internal organs of the sick chickens, and hurriedly said: "The garbage in the village is cleared every day, and the chicken feathers and internal organs of those sick chickens should have been transported away long ago." ”

Gu Yanan turned around, "We don't go to the garbage dump, we want to go to the crescent moon lake to investigate the situation of wild migratory birds." ”

Jin Zhi chased after him and asked, "Are our chickens suffering from chicken plague?" ”

"It's not clear yet, but it's estimated to be a very serious bird flu." Lu Centrifugal spoke straightforwardly, with a kind reminder, "So, don't eat the sick chicken anymore." ”

Jin Zhi and Jin Zhi's mother-in-law agreed again and again.

Lu Li instructed the two of them some precautions on the prevention of avian flu before leaving with Gu Yanan.

The suburbs of Lianhai City, the Crescent Lake Scenic Area next to Lijia Village.

This is a wetland park that has just been developed in Lianhai City in recent years, there are more than a dozen large and small lakes, the largest of which is the Crescent Lake, which is full of wild birds, attracting many tourists to sightsee.

Gu Yanan showed his work card, and the on-site flow shunting of the CDC was easy to enter the scenic spot.

The car was parked in a parking lot next to Crescent Lake, and Gu Yanan and Lu Li got out of the car with the sampling box.

There are many tourists playing on the shore of Crescent Lake, and there are patches of waterfowl on the lake.

Because it is autumn, there are many migratory birds on the shore that pass by here to rest and go to the south for the winter.

Some tourists tried to approach the flock, startling a flock of birds on the ground.

Lu Li knew that Gu Yanan wanted to sample these wild migratory birds, but he didn't bring a bird trap today.

Lu Li sighed with questions, "Li Guoqing's wife said that they caught wild birds to eat by the Crescent Lake, how did they do it?" ”

Gu Yanan did not answer, but walked towards a forest next to the Crescent Lake with the sample.

It was a wild poplar forest, and the trees were full of fallen leaves, and from time to time birdsong could be heard.

There was a faint path in the woods that had been stepped on.

Gu Yanan carried the sampling box and walked more than ten meters along the path into the woods, and suddenly stopped.

Following Gu Yanan's gaze, Lu Li raised his head and found several dead birds hanging between the two poplar trees above.

How can a dead bird hang in the air? You can't go up to the world, you can't touch the ground.

If you look closely, there is a fine net between the two poplar trees.

The network cable is extremely thin, hidden in the woods, if there is nothing.

Lu Li stood under the net, looked up at the dead birds hanging in the thin net, and finally reacted, "This is a hunting net used to catch birds?!" ”
