Chapter 472 Guo Family Village
Brucellosis is a notifiable infectious disease included in the B list.In China, there are three main types of brucellosis transmission, bovine, sheep, and swine.When animal products carrying Brucella come into contact with human mucous membranes, it is possible to cause illness.The disease is highly contagious and can cause symptoms including fever, joint pain, nerve damage, reproductive system damage, and more.Most troublingly, there are six different classifications of clinical human infection with brucellosis—subclinical, acute, subacute, chronic, localized, and recurrent.

Chronic infection can easily be misdiagnosed as neurosis, and acute infection can be left behind, including but not limited to back pain, joint pain, sciatica, etc.Among the case reports of ovine brucellosis, fixed and persistent arthralgia was the most common.

If the mysterious disease that the villagers of Guojia Village are suffering from is ovine brucellosis, it could explain Guo Ying's back pain.

Sun Lien shook his head and said, "If goat milk is not boiled and specially processed, it will have a very strong fishy smell. Most people can't accept this kind of smell." He explained seriously, "If you usually drink brick tea in the village , then the coverage of the age group is very wide. But if the milk tea you usually drink is mixed with raw goat milk, then the people who can drink it should be mainly concentrated in the middle-aged and elderly people who are not so keen on taste.”

Sun Lien's reasoning angle was a little too tricky, Director Huang Wenhui couldn't keep up with his rhythm for a while, "Do you think... goat milk is okay?"

"If there is a problem with goat milk, the number of infected people should be much higher than it is now." Sun Lien said seriously, "And there will be more people who will die or suffer serious sequelae. Severe pain with fixed joints, but It's not a symptom that can be easily overlooked." When he said this, his complacency at the beginning suddenly disappeared, replaced by confusion, "I think it should be fluorosis, but...the fluorine content in the water is obviously not high enough."

There is certainly not enough fluoride in the water to cause fluorosis.Otherwise, the symptoms of fluorosis will appear on those young people. Although they are not used to drinking milk tea mixed with goat's milk, they always drink the water in the village.

"Then... is there a problem with brick tea?" Director Huang continued following Sun Lien's train of thought, "I've heard that some ethnic minorities in border areas can't do without tea for a day. And brick tea edge tea itself is made of old leaf tea stalks Made by compression and fermentation, the fluorine content is two to three hundred times higher than that of ordinary commercial tea...Drinking a lot of brick tea and side tea for a long time may indeed cause fluorosis..." When she said this, she felt something was wrong, "But Guojia Village The amount of brick tea the villagers drink obviously hasn't reached that level yet, right?"

Not enough.Sun Lien nodded lightly, "They are not frontier ethnic minorities who lack food sources. They must drink tea to supplement relevant nutrients!" Residents drink it every day, even without missing a meal, and even simply replace water with tea to cause fluorosis.Compared with them, the total amount of brick tea and side tea that the villagers of Guojia Village usually drink is obviously insufficient.

What other pathways might lead to fluorosis?Sun Li'en frowned, took out his phone and began to check the information.

There are so many factors that can make a person sick that no doctor can keep them all in mind.When encountering problems in fields that they are not familiar with or do not master, the safest way for doctors is to consult other colleagues or seniors who have mastered this field.

For example, Sun Lien called Brother Pheasant in the fourth courtyard.

But obviously, there is no pheasant brother waiting to respond to Sun Lien's call, and even Sun Lien himself is not sure whether the one who is coming from the opposite side is a bad boy from another hall, or a passerby wearing a strange cosplay costume.

Fortunately, the mobile phone network signal in Guojia Village is good, and Sun Lien found the relevant documents very easily.

"Water-drinking fluorosis, tea-drinking fluorosis...and coal-burning fluorosis?" Director Huang, who was looking at his phone beside Sun Lien, spoke out first, "Which one do you think they are?"

"The total amount of drinking water is not enough, and drinking tea may not be enough..." Sun Lien rubbed his chin thoughtfully, "Although they used a brazier, the fluorine content of peat should not be as high as that of coal in the southwest Bar?"

"Calculated simply by the fluorine content of coal, the fluorosis in Southwest China is unreasonable. The fluorine content of their coal is only 99mg/KG, which is actually much lower than that in other regions." Director Huang looked at Sun Lien Laughing, "You haven't used a coal stove before, have you?"

Sun Lien shook his head honestly, he had never used briquettes or stoves that burned loose coals. "I haven't used it. Is there anything special about it?"

"No matter where it is, heating or burning coal for cooking is a matter of cost. Although the whole coal burns with strong firepower, it doesn't last long, and the price is a bit expensive." Director Huang explained , "More importantly, such coal stoves are too dirty and inefficient, and at the same time they cannot effectively use those naturally degraded coal powders."

Sun Lien didn't understand what he heard, but as a good listener, he knew when to ask, "And then?"

"Then people invented the method of shaking briquettes." Director Huang Wenhui shook his head and said, "Sprinkle some water into the coal ash, then mix it with loess or clay in proportion, shake it with a dustpan, and then the coal ash can be fused into a larger one." lumps of coal."

Seeing Sun Lien's still confused look, Director Huang was a little angry, "Haven't caught the point yet?"

"No." Sun Li'en shook his head honestly, "Then coal briquettes evolved into briquettes with better combustion efficiency. I can guess this too. But what does this have to do with fluorosis?"

"Loess, clay!" Director Huang stood on tiptoe and tapped Sun Lien's head, "The fluorine content in the coal is not high, but there is in the soil!" She turned to the bewildered village party secretary and asked, "You guys Does the village have the habit of rolling briquettes or pressing briquettes by themselves?"

"Yes, yes." The village party secretary was finally able to answer this question, "Indeed there are."

"I'll call the Centers for Disease Control and Prevention now." Huang Wenhui nodded, "Let them come over and take a sample and test it." She looked at the stunned Sun Lien, and laughed, "Boy, learn a little bit!"
