Several gently sloping hills at the foot of Qingcheng Mountain are trapezoidal rice fields, which are quite large-scale, with Lijia Village as the center, and the surrounding terraced fields are covered with sticky rat boards and rat traps.

From the time the sun first rose until noon, when the sun became hot, Gu Yanan and his party finished placing all the rat traps they brought.

When I was about to go to Lijia Village to meet Section Chief Pang and his party, there were still many farmers in the surrounding rice fields who were cutting rice.

"What are you doing? Looking at these things like cages, what's the use of grabbing them? ”

"Catch voles." Xiao Chu explained.

The questioning farmer coughed twice, "What are you doing catching voles?" It's weird and disgusting, can you still eat this thing? ”

"It's not for eating, but for experimenting and testing, there has been a recent epidemic of scrub typhus in this area, and the chigger mites on voles are the vector, and we will go to the village to mobilize the villagers to carry out rodent extermination operations after a while."

"Ahem, ahem...... What is scrub typhus? A lot of people in the village have been sick recently, is this scrub typhus? ”

Xiao Chu was about to answer, Gu Yanan's eyes were sharp, and he found that there was a black spot behind the ear of the villager who was asking.

"Wait a minute!" Gu Yanan spoke, and at the same time approached the side of the farmer who spoke, and looked closely behind his ear, there was a round black eschar.

"Don't move! What's wrong behind your ears? ”

The farmer who spoke panicked and was about to reach out and scratch behind his ear, but was grabbed by Gu Yanan, "You can't scratch, be careful of the spread of infection." ”

Gu Yanan asked, "Have you had any fever symptoms lately?" ”

"Ahem, cough, I started to have some low-grade fever yesterday, and I was nauseous, but it's nothing, I think I've been tired from farming recently."

"When did the eschar behind your ears start?"

"Eschar?"

"It's the black bloody scab behind the ear."

"Oh, I scratched the back of my ear for the first two days, and then I scratched it, and then it broke, and a hard lump grew."

Gu Yanan said with certainty, "You should have been bitten by scrub mites when you were working in the fields recently, and you had better go to the hospital to have a look, you already have the early symptoms of scrub typhus, if not treated in time, the symptoms will get worse and worse." ”

The villagers who spoke remembered that many people in the village had a fever and nausea first, and then they were in pain, and they couldn't walk on both legs before going to the hospital.

You can't be like them, will you?

The more I thought about it, the more frightened I became, and the villagers stopped cutting the rice and hurried home with sickles.

Looking at the backs of the villagers leaving, Gu Yanan thought to himself, it seems that the scrub typhus epidemic here is more serious than expected.

In addition to catching wild rats to cut off the transmission chain, it is also very important to educate villagers about scrub typhus in a timely manner.

Gu Yanan and his entourage rushed back to Lijia Village to meet Section Chief Pang, and gave an explanation on the spot, especially about preventive measures, try to wear long sleeves and long pants when cutting rice, and stuff the trouser legs into socks......

In the afternoon, Gu Yanan and his party went to the rice field to collect sticky rat boards and rat traps.

The harvest was quite good, and dozens of wild mice were caught.

That night, the captured wild mice were sent to the CDC laboratory.

Because of the large number of wild mice caught, the workload of finding chigger mites from the wild mice is huge, so the emergency team stays in the laboratory to work overtime to help.

Chigger mites are small, less than a millimeter in size, dark red, densely covered in mouse hair, and it is not easy to isolate them.

It was late at night to be processed and the rats were recovered, and it was already 1 a.m. when the scrub typhus carried by wild mice and scrub worms were tested.

When he got the results, Gu Yanan was surprised to find that the poisoning rate of wild rats in the rice fields around Lijia Village was as high as 30%.

This figure is much higher than in previous years for routine monitoring.

It appears that scrub typhus is being broken in the wild rat colony near Lijia Village, and humans living in the vicinity have been affected, and there is also an epidemic of scrub typhus.

Rodent density control operations should be carried out as soon as possible.

On the second day, Gu Yanan took the emergency team to Lijia Village again, this time bringing more sticky mouse boards that are convenient for the villagers to use, and went to the rice field to demonstrate with the villagers.

Gu Yanan also contacted clinicians from the city hospital and formed a medical team to give free medical examinations to Lijia Village and nearby villagers, and villagers with early symptoms of scrub typhus were promptly sent to the hospital for treatment.

Over the course of several days, the city's emergency response team and the hospital's medical team traveled to several villages near Mount Qingcheng.

At the same time, the county CDC publicized and helped the villagers to carry out rodent eradication activities.

Symptomatic villagers were treated in a timely manner, there were no deaths, no new cases within a week, and the peak of scrub typhus in autumn near Qingcheng Mountain in Lianhai City was finally brought under control.

——

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on the scrub typhus outbreak.

Mount Qingcheng is the natural focid of scrub typhus in Lianhai City.

This autumn, the density of wild mice in the rice fields under Qingcheng Mountain was higher than in previous years, and the transmission rate of scrub mites in wild mice was also higher than in previous years.

In the process of harvesting rice, the villagers came into contact with chigger mites on the wild mice and were infected with the scrub typhus oriental body.

Zheng Qi, a photography enthusiast, came into contact with a wild mouse during the wind collection process and became infected.

As a result of the rodent eradication campaign, the chain of transmission was cut off and no new cases were reported.

The patients with scrub typhus were treated with antibiotics and all recovered and were discharged from the hospital, with no deaths.

After writing a simple summary report, Gu Yanan will file the report.

When he was about to get off work, Gu Yanan received a phone call, it was the landlord next door.

The landlord's aunt told Gu Yanan that her house had been sold, so her lease contract with Gu Yanan would be terminated after three days, and according to the terms of the contract, the landlord's aunt voluntarily paid her three months' liquidated damages.

Gu Yanan was worried, the house next door was rented by her from the landlord's aunt and given to Nan Han for free.

At that time, she was worried about Nan Hanfei's financial problems and had to take care of his self-esteem, so the house next door belonged to her friend and could be lived in for free.

Now that she was suddenly given only three days, Nan Hanfei was asked to move out, and she didn't know how to speak for a while.

After thinking about it, Gu Yanan felt that he had told Nan Hanfei about letting him move out before, and listening to him, the old mansion on Minguo Road should have been renovated, and he should have a place to live when he moved out.

So Gu Yanan called Nan Hanfei and said directly, "Nan Hanfei, tell you a news, the aunt next door called me just now, she said that she was coming back from abroad in three days, so the house can't continue to live in......"

"Understood, I'll move out in the next two days, thank you these days, and invite you to dinner another day." Nan Hanfei's reaction was very crisp, with a faint smile in his words.

"You're welcome, do you want me to help you move?"

"No, I can do it by myself, and when I move in, I'll go to you and invite you to dinner, and we'll make an appointment."

"Okay."
