The chalet is located on the edge of the meadow, the roof chimney is still smoking, the alpine meadow, the creek of the wooden house, the mountain flowers are full of flowers, accompanied by wisps of cooking smoke, like a landscape painting of paradise.

Ye Zhenzhen walked to the nearest stream of water first and leaned over to collect water samples.

The water here is crystal clear, and there is no shadow of a snail in sight.

Zhang Xiaobin fished a few times under the water with a fishing net, did not catch a snail, wanted to change places and try again, suddenly remembered the owner of the wooden house, Grandpa Zhang, when he was a child, he came here to catch fish and swim, and he did not eat the good things given by Grandpa Zhang.

Xiaobin was the first to walk to the cabin and shouted, "Grandpa Zhang, are you at home?"

No one responded, and soon there was a sharp cough.

Realizing that something was wrong, Zhang Xiaobin rushed into the wooden house.

Nan Zhiqiao, Ye Zhenzhen and Qianqian followed closely behind and also entered the wooden house.

The furnishings in the wooden house were simple and orderly, the iron pot on the stove was steaming, the wood crackled and burning under the stove, and in front of the stove, an old man with gray hair was squatting on the ground and coughing violently.

Zhang Xiaobin half-squatted beside the old man, stretched out his hand to pat his back, but the old man still coughed.

Xiaobin exerted force in his hand, wanting to give the old man a good breath, but suddenly, the old man made a strange sound from his throat, as if something was stuck in his throat, the old man couldn't breathe, and his face turned purple.

Ye Zhenzhen also stepped forward to help, and patted the old man's back with her right hand.

"Ahem......"

The old man finally coughed out, and at the same time coughed up a large mouthful of blood, which sprayed on the ground.

The old man breathed a sigh of relief, but when he saw the blood on the ground, the old man was shocked into a cold sweat, his face was red and purple, because of the fright, he instantly turned white, stared at the blood on the ground, and muttered incoherently: "Gu ...... Gu worms, Gu worms are coming......"

Everyone's eyes were focused on the pool of blood on the ground, the blood had just been coughed up by the old man, a bright red pool, and there was a living creature wriggling in the center of the bloodstain.

When I got closer, it was a series of slender little insects, each as long as a knuckle, thin, black-brown, like a knotted silk thread tangled together, and a large number of insect bodies were constantly writhing in the blood, making people's cold hairs stand on end.

Qianqian had never seen such a terrible scene, so she hurriedly hid behind her cousin and exclaimed, "Ah...... There are so many bugs, it's disgusting. ”

Ye Zhenzhen thought of the schistosomiasis patients who had been appearing here recently, and compared it with the symptoms of the old man in front of him, who lived in a schistosomiasis-infested area, and the blood he coughed up had filamentous worms.

Schistosoma adults, dioecious, males about 15 mm, females slightly larger, about 20 mm, males and females often hug together, resembling nematodes.

The bugs in the blood stains on the ground in front of me are exactly the same as the description of schistosomes in the book.

Ye Zhenzhen comforted her cousin Qianqian, "Don't be afraid, it's just some schistosomes." ”

"Schistosome? But the old man said what kind of worm this is. Ye Qianqian said as she glanced at the old man in front of the stove with her eyes.

Although the old man stopped coughing at this time, his face was worse than just now, not only because of his physical discomfort, but also because he was frightened by the insects in front of him.

Nan Zhiqiao said suddenly: "Water Gu is another name for schistosomiasis, there was an epidemic of schistosomiasis in my country very early, at that time people did not know what the pathogen caused schistosomiasis was, only knew that in some epidemic areas, as long as people come into contact with the infected water, they will be infected, and the insects in the infected water will penetrate the skin and drill into the human body, and over time they will become a big belly, skinny, and finally die in pain, people give this disease a terrible name, that is, water Gu." ”

Zhang Xiaobin helped the old man to sit on the chair next to the stove and asked with concern, "Grandpa Zhang, how are you feeling?"

The old man hadn't recovered yet, his eyes were still on the schistosomes that were wriggling in the bloodstains, and he said to himself: "How can this be, how can I be entangled in the water Gu......"

"Grandpa Zhang?" Zhang Xiaobin shouted again, trying to calm the old man in front of him.

Nan Zhiqiao looked around the wooden house and noticed that there seemed to be a person lying in the bedroom inside.

glanced at Ye Zhenzhen, and Zhenzhen immediately understood, and the two walked into the bedroom at the same time.

On the bed in the bedroom, an old woman with gray hair was lying on the bed, her eyes were closed, her face was pale, and there were large and small medicine bottles on the bedside table, the most conspicuous of which was aspirin antipyretic analgesics.

Ye Zhenzhen leaned over to the ear of the old woman on the bed and called softly, "Grandma Zhang......"

No response.

Ye Zhenzhen touched the old woman's forehead with the back of her hand, and her forehead was hot!

The situation is not good! Ye Zhenzhen hurriedly raised her voice and shouted again, while nudging the old woman.

Still unresponsive, the old woman turned out to be unconscious.

Nan Zhiqiao walked out of the bedroom and asked the old man who was still in a state of shock, "What are the symptoms of the patients in the house before they fall into a coma?"

Speaking of his wife, the old man came back to his senses completely, stumbled back to the bed side of the bedroom, shook his wife with his hand, and shouted: "Old woman, wake up......"

Ye Zhenzhen stood aside, "She has entered a coma, she can't wake up, before this, what symptoms did she have? I see that there is painkillers at the bedside, does she feel pain somewhere?"

The old man said in a trembling voice: "A week ago, the old woman said that her head hurt a little, and there was a fever, I thought it was a cold, so I went to the pharmacy under the mountain to buy cold medicine and painkillers, and I didn't get better after two days, I was going to take her to the clinic in the town these days, but I also felt tired, coughing badly, so I kept dragging it, and when I got up this morning, the old woman was not quite right, she has been groggy and asleep, and she didn't eat lunch, I just wanted to boil water to cook some food for her, but I didn't expect ......."

The old man choked up for a while, and Nan Zhiqiao immediately decided, "Let's go, now send these two old men to the nearest hospital." ”

The nearest hospital to this small village in the mountains is the county hospital, Nanzhiqiao has an off-road vehicle at the entrance of the village, you can drive there, but from the wooden house to the entrance of the village, there is still a long mountain road, the old woman is unconscious, the old man coughs non-stop, and can not walk at all.

"Xiaobin and I, one on our backs, hurry up. ”

The old man was lean, Zhang Xiaobin was responsible for carrying it, the old woman was bloated, Nan Zhiqiao was responsible for carrying it, walking on the rugged mountain road, and almost fell down a few times, but fortunately, Ye Zhenzhen and Qianqian were around to follow, and from time to time they helped to support the two.

Finally walked to the entrance of the village, got on the off-road vehicle, and when I arrived at the nearest county hospital, it was already two o'clock in the afternoon, and after a rough examination, because of the restrictions of medical conditions, I was directly transferred to the city hospital, that is, the hospital where Xiaobin's parents lived.

After some tossing, it was already evening.

With the previous experience, the city hospital quickly made a diagnosis, both old people were acute schistosomiasis, the old woman had ectopic parasitism in the brain, and the old man had ectopic parasitism in the lungs.

With the addition of the two new elderly people sent today, the number of acute schistosomiasis patients gathered in the city hospital has reached more than 20, which is an unprecedented situation.
