[The sun] seems to be calm and beautiful, no one knows what kind of crisis is hidden behind it, and the seemingly clear flowing water in Tibet will attract insects to the body if you are not careful, and it is talking about all kinds of parasites hidden in the water.
The 2015 Nobel Prize in Physiology or Medicine was awarded to researchers who have contributed to parasitic diseases, which shows how much attention is paid to parasitic diseases.
Why is it said that clear water is dangerous? What happens if half of your liver is missing?

A doctor's statement
Before we get into the main content, let's take a look at the case of a doctor about the dangers of parasites, and before that, he had just finished a day of surgery to deal with parasitic diseases, liver echinococcosis.
The inner capsule of hepatic hydatid worm becomes more and more chilly in the back, which is easy to cause discomfort, and the gauze used in the operation has been paved all over the ground, and some people may think that this patient should be very fat after looking at the picture.
In fact, this patient is only 97 pounds, and he is a male, you can imagine how powerful the parasite is, and this disease is a common parasitic disease in pastoral areas, hepatic echinococcosis, this patient, although the liver is saved, but the removed part is not small.
Another netizen shared that a male colleague of his went to Tibet to play for a few days, because he was unprepared, he was infected with hydatid worm, and he became ill after he went back, and because no one in the local area had seen hydatid disease, he thought it was a terminal illness.
But fortunately, when the life was big and he was about to hang up, he met an old doctor who used to aid Tibet and remembered that he had this disease......
Raw water is not holy water
I once heard an online story about a friend who traveled to western Sichuan and excitedly tasted a sip of mountain spring water, he thought that the water was clear and transparent, and there should be no problem, however, what he did not expect was that the consequences of this saliva almost cost him his life.
The reason is that the seemingly clear water hides countless microorganisms and parasites that are invisible to the naked eye, such as amoebas and giardia, which can remain active even in cold alpine environments, and if accidentally touched, can cause human infections and diseases.
There are also netizens living in Tibet who shared that the water in Tibetan areas should not be drunk casually, because it looks clear and may actually have all kinds of parasites, plague, animal carcasses, and animal feces, only unexpected.
The reason is actually very simple, animals carry parasites, those parasites will excrete eggs with the excretion of animals, near the water source, not only people will take water, animals will also move near the water source, once the feces or animal carcasses are soaked in the water, the parasites will live in the water.
Shiqu County, Sichuan Province, is an area with a high incidence of echinococcosis, a disease that is particularly common on the grasslands and is known as insect cancer, which is extremely well tolerated and can survive in temperatures as high as 80 or 90 degrees, and it is difficult to kill it at low temperatures.
Dogs act as intermediate hosts, making it difficult to completely eliminate pathogens even in highland areas, even if boiling water, many people like to come into contact with local Ao dogs, but are unaware of the potential dangers, hydatid disease cannot be completely cured theoretically, and patients need to continuously remove the foci of infection.
Some parasites are resistant to high temperatures, but partly because of the altitude in Tibetan areas, which causes the boiling point of water to become lower, and it looks like the water is boiling, but in fact the temperature is not yet up to the temperature to kill the parasites.
It is precisely in this way that many netizens shared their own practices, when they go to Tibetan areas to play, take a portable pressure cooker, use the pressure cooker to boil water, or buy bottled water directly, in short, don't drink raw water directly.
Many people mistakenly think that the water source in the no-man's land is absolutely clean and free of chemical pollution, but in fact there may be microbial contamination, and a mouthful of water may contain tens of thousands of eggs.
Therefore, friends, when traveling, especially when going to places with beautiful natural scenery, the importance of safe drinking water cannot be overlooked, and do not judge whether water can be drunk directly based on the appearance alone, because sometimes the vision can mislead us.
A Tibetan girl had insect cancer, and two catties of worms were taken out by surgery
Having said that, we are looking at a case of a girl from a herding family in Tibetan areas who suffered from a special disease, worm cancer, which is a high incidence in the western region where agriculture and animal husbandry are the main areas.
In 2017, Liu Di was still a sophomore in high school, about to enter the third year of high school, facing graduation, for her, the college entrance examination is in her hands, the most likely opportunity to change her fate, in order to enter the university of her dreams, she has begun to go all out to prepare for the exam.
Liu Di suddenly felt severe abdominal pain in the classroom and eventually fainted, the teacher quickly rushed her to the hospital, and the parents who hurried to learn a disturbing news from the doctor, "Your daughter has a lot of worms in her body, and we initially suspect that it is hepatic echinococcosis." ”
Her parents are herdsmen, and they don't know much about this disease, and their first reaction is that their daughter has eaten something bad and has roundworms in her stomach, and she wants the doctor to prescribe worming medicine, and the doctor persuades Liu Di to stay for treatment, and now the certainty of cure is very high.
I insisted on going back to school, and finally Liu Di entered the university as she wished, and two years have passed, and her symptoms began to become more obvious on campus, her eyes and skin were yellowing, and when she arrived at the hospital, the doctor told her that it was too late.
The doctor explained to her that the incubation period of the disease can be very long, and the case fatality rate can exceed 94% within 10 years, and in her case, the hope of a cure is very slim, and in Tibet, many doctors even regard this kind of worm cancer as the "primary cancer".
Liu Di is now in the terminal stage of hepatic echinococcosis, and the parasite has occupied the liver, because of the pressure on the liver, resulting in serious damage to liver function, the bile ducts are compressed, and the bile cannot be discharged, resulting in yellowing of the eyeballs and skin.
The doctor found that her liver was overweight by two catties in the operating room, which is equivalent to saying that the weight of two catties is parasites and eggs.
Liu Di's condition once puzzled her parents: how did she get infected with these bugs when she didn't have a dog at home? After investigation, the reason was revealed: there is a clear stream near Liu Di's house, the stream water is sweet, Liu Di's mother often goes there to get water for cooking, and most of the family's water comes from this.
Most of the surrounding nomadic families also use this method to obtain water, Liu Di used to play by the stream when he was a child, and when he was thirsty, he drank the water directly, however, along this stream, in addition to humans, various animals and livestock also came to drink.
When Echinococcus granulosus lives in the small intestine of dogs matures, the eggs are excreted and excreted in the feces, which contaminates water and the environment.
Friends, when you go out, safety and health are your own, especially in the natural environment, be cautious and cautious.
