When we talk about the word "hope that you are well", we mostly greet our long-lost old friends and express our concern.
In fact, when the word "I hope you are good" was invented, I didn't worry too much, but I didn't like it a little. When the ancients met, they asked each other, "Brother De, hope that you are well!" More meaning, this brother, long time no see. You don't have scrub typhus, do you? Don't give it to me!
Of course, if you have to understand it as "long time no see, how have you been recently?" You don't have scrub typhus! " It is also possible.
tsutsugamushi disease
Chigger mites are not common in modern people, but they are very powerful.
A few days ago, there was an example in Foshan, Guangdong. After a girl went up the mountain to sweep the grave, she came home and found a pimple on her shoulder, and she didn't care at that time. A week later, she began to have repeated fever, and the highest temperature was as high as 40 degrees Celsius. At first, she was treated as a common fever and cold. After a persistent high fever, she went to the hospital for examination. Doctors found that papules are the unique eschar of tsutsugamushi disease. After the treatment of tsutsugamushi disease, the girl gradually returned to normal temperature.
The doctor also specially reminded that severe tsutsugamushi disease can be fatal.
Sick is a cannibal, the kind that eats people's hearts?
The book Yi Zhuan in the Warring States period explained "innocence" in this way: "There was grass to live in camps in ancient times. Being sick, eating people and eating people's hearts, so people who ask for help are innocent, not because they are sick. " According to Yi Zhuan, "Chigger mite" is an insect that lives in the grass. This kind of insect is characterized by "being good at eating people's hearts", just like cannibals, not diseases.
The chigger mites mentioned in the Book of Changes are actually very similar to chigger mites. Chigger mites move in the grass on the ground after hatching. When it meets the host animal or human, it will adsorb to the surface and absorb tissue fluid. Chigger mites are not as greedy as grasshoppers (ticks). Generally, it will land for 3-5 hours and develop into larvae and adults. Chigger mites usually only bite the host animal once in their lives.
The ailment mentioned in the Book of Changes is "eating people and eating people's hearts". Yi Du Jun understands that people will be abandoned after being infected with tsutsugamushi disease, just like insects entering their bodies. And people infected with tsutsugamushi disease have a certain mortality rate. In the report of 200 cases of scrub typhus in Guangzhou, the mortality rate is as high as 5%, which is still available in modern society with developed medicine. In the Warring States period, when the medical level was backward, the mortality rate was unimaginable.
Repeated fever and eschar? You may have tsutsugamushi disease.
Tsutsutsugamushi disease is a natural epidemic disease transmitted to people through chigger mite larvae. The term natural focus disease may sound a little confusing to everyone. Just give a few simple chestnuts to understand that infectious diseases such as rabies and plague spread to other animals or people through infectious sources produced in nature, which are called natural focus diseases.
The ancestors' fears are indeed justified. Tsutsutsugamushi disease is different from lice and fleas, and it is life-threatening to be infected with this parasite.
After the infection of tsutsugamushi disease, the characteristics of the disease are very similar to those of common fever and cold. Many people regard this disease as a common recurrent fever, which may lead to death after severe symptoms.
However, except for fever, the characteristics of tsutsugamushi disease are very different from those of common fever and cold. After the onset of tsutsugamushi disease, it will produce eschar or ulcer, but it is painless, which is also an important factor to judge tsutsugamushi disease. There will also be symptoms such as swollen lymph nodes and rash.
But you don't have to worry like the ancients. Tsutsutsugamushi disease is similar to rabies, and there is little chance of human transmission. Of course, if the chigger mites on the other side don't climb on you.
Tsutsutsugamushi disease is at the poles.
At first, tsutsugamushi disease was a "southern disease". Mr Li Shizhen said in Compendium of Materia Medica that tsutsugamushi disease is a kind of fever prevalent in Lingnan area. Until 1980s, tsutsugamushi disease was considered as an active disease in southern China.
1986 After an outbreak of tsutsugamushi disease in Shandong Province, tsutsugamushi disease marched northward like Zhu Yuanzhang, the Ming Emperor. And gradually spread in the region, successively "occupied" Tianjin, Jilin, Liaoning, Heilongjiang, Gansu, Xinjiang, Shaanxi, Hebei and other northern provinces. Tsutsutsugamushi disease invading the north is not limited to the previous disease forms, but has developed new characteristics of autumn and winter diseases.
The limited development of tsutsugamushi disease in south China is not far behind, although most of them maintain the fine tradition of onset in summer, and some of them occur in autumn and winter. However, due to the warm environment in the south all the year round, there are still a few cases of tsutsugamushi disease that can overcome the comfortable autumn and winter attacks (except in Guangdong, too warm may occur all year round).
However, in the species of infected animals, the focus of tsutsugamushi disease in the south can be thrown out of several streets in the north. There are more than 20 species of infected animals found in southern epidemic areas, mainly Rattus flavipectus, Apodemus agrarius and Rattus flavipectus. At present, only Apodemus agrarius, Apodemus dalmati and hamster are confirmed as carriers in northern epidemic areas.
Mouse: I'll carry the pot.
A picture of the big coffee in the parasitic world in summer
Next, read Jun to introduce you to several big coffees that occupy the creepy C position on the "parasites" with tsutsugamushi disease.
Acari is well-known among several big coffees. Everyone gave him many nicknames, except the Parthenocissus, ticks and ticks. Ticks generally suck blood for a long time, so when people in Northeast China are described as insatiable, they will say that you are like Parthenocissus. Acari can spread forest encephalitis, Xinjiang hemorrhagic fever and other diseases, and there were deaths in 2009.
Leech, also called leech, is one of Yi's childhood shadows. I remember watching a movie when I was a child. In the forest, a person was unconsciously sucked up by leeches, which still made Du Jun feel cold in his back. But leeches are not as greedy as ticks and will leave when you are unprepared. People have also studied the medicinal value of leeches. There are leeches in Chinese medicine, and there are also treatments for leeches to bleed in Europe.
Schistosoma japonicum is a notorious parasite. When the epidemic situation of schistosomiasis was eliminated, Chairman Mao personally wrote two seven-tune "Send to the God of plague". "Sit on the floor, travel 80,000 miles a day, and look at thousands of rivers." It comes from here.
In addition to the common insects that enter through the mouth, Schistosoma japonicum can also be infected by puncturing the skin of people and animals. There are many complications in patients with advanced schistosomiasis, the most common one is hepatitis B, and the mortality rate of Schistosoma japonicum is the highest among the above parasites, so it is a well-deserved C coffee.
Putting a Schistosoma japonicum is all about loving your style.
Paederus is not a parasite in the strict sense, but it is also a very annoying insect. Paedelweiss will appear erythema after contact with human skin, and there will be itchy and painful symptoms. Seriously tell everyone, don't kill this bug when you find it. The blood sprayed after killing will only make the allergic situation worse. Just get rid of it! ! !
Sure enough, all beautiful colors are poisonous.
Although tsutsugamushi disease looks terrible, it is actually traceable.
The pathogen of tsutsugamushi disease is called orientia tsutsugamushi. The pathogen is cold-resistant and heat-resistant, and can survive for 5 weeks at MINUS 20 degrees Celsius, but it can be eliminated after heating at 56 degrees Celsius 10 minute, so it is extremely sensitive to general disinfectants.
Tsutsutsugamushi disease is a bit deceptive, and foreigners often enter the epidemic area. Male cases are also slightly more than female cases. Occupation is also obvious, farmers and field workers have more diseases. Nightingales, training and combat troops are susceptible to infection, which also shows that infection is related to the probability of being attacked by chigger mites.
Because there is no vaccine against tsutsugamushi disease at present, it is very important to prevent it before it happens.
When doing outdoor activities, try not to expose your body, avoid sitting and lying in places with many weeds, and use insect repellent to prevent it. Most of the carriers of chigger mites are rodents, so it is particularly important for the prevention and treatment of tsutsugamushi disease to drive away rodents.
Of course, the best way to prevent this is to forward this article to your fat friends and let them know, hello, I am good, hello everyone!
Remember, the next time you see a friend, ask first: Brother De, how are you?
