Niu Tiangou returned home, and Dr. Xue Lian had already prepared a meal and was waiting for him. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After eating, Niu Tiangou finally couldn't help but tell her about Zhang Dalong's situation.

Doctor Xue Lian frowned slightly after hearing this, but she was not particularly surprised, glanced at him a few times and said: "Do your business, you are messing around in the young lady's pile all day long, your ears and eyes are stained, and the fragrance is tempting, if you don't have enough concentration, it is difficult to 'get out of the mud without staining', and there is nothing strange about suffering from those messy diseases." ”

"Is this sexually transmitted disease the 'flower willow disease' that I used to say? It...... What are the types? Niu Tiangou didn't care about her eyes, and asked anxiously. He had seen some "flower willow disease" in the novel before, but he only knew that it was a dirty disease that was easy to get when the sons and brothers were looking for flowers and asking willows in the past, and he really didn't know much about these aspects.

"There are many types of STDs." Dr. Xue Lian looked away, thought for a moment, and said, "They are mainly transmitted through sexual activity, and the lesions occur in the genital area, including syphilis, gonorrhea, chancre, venereal lymphogranuloma and inguinal granuloma, which used to be called 'flower willow disease'.

"At present, there are more than 20 kinds of sexually transmitted diseases listed abroad, including the traditional five sexually transmitted diseases and non-gonococcal urethritis, genital warts, genital herpes, bacterial diseases, vulvar candidiasis, trichomoniasis, scabies, pubic lice, hepatitis B, AIDS, etc.

"The eight sexually transmitted diseases that China currently requires to focus on prevention and treatment are syphilis, gonorrhea, chancroid, lymphogranuloma venereum, genital chlamydia trachomatis infection, genital warts, genital herpes, and AIDS. Among them, gonorrhea is currently one of the most common sexually transmitted diseases in the world.

"More than 20 kinds? Also includes AIDS? Niu Tiangou opened his mouth wide, "It's all through...... Is sexually transmitted? ”

"More than 90% of the transmission is through direct sexual contact, including sex, kissing, skin-to-skin contact, hugging, etc., and of course, indirect sexual contact can also be infected.

"For example, items used by STD patients, including clothes, bedding, utensils, toilets, toilets and bath towels, may be contaminated by the patient's secretions and carry germs, and healthy people who live closely with STD patients are easily infected when the minor wounds that are barely felt come into contact with these items stained with pathogenic bacteria, and bathrooms, especially public baths, may also be an important place for STDs."

Hearing this, Niu Tiangou was secretly shocked in his heart: No wonder Zhang Dalong, this kid, insisted that Wu Sangui move out, it seems that the doctor ordered him.

Dr. Xue Lian continued: "In addition, there are bloodborne infections and placental and birth canal infections.

"For example, some patients with sexually transmitted diseases have a long course of illness and may be infected with pathogens but may have no clinical manifestations, such as latent syphilis, HIV infection and hepatitis B surface antigen carriers, etc., and healthy patients or patients with various other diseases can be affected by transfusing blood or blood products provided by them.

"There is an incubation period for general sexually transmitted diseases, such as syphilis, which has an incubation period of 2~3 weeks; gonorrhea is 2~10 days; 1~3 weeks for non-goorthrhoea; Genital herpes is 2~20 days, an average of 6 days; Lymphogranuloma venereum is 6~21 days, with an average of 7~10 days; Genital warts have the longest incubation period, which is 3 weeks ~ 8 months, with an average of 3 months.

"If a pregnant woman has a sexually transmitted disease that is not detected and treated in time, or if the treatment is not complete, the pathogen of the sexually transmitted disease can be transmitted to the fetus through the blood circulation of the placenta, such as syphilis, AIDS and hepatitis B; When a fetus is infected through the birth canal with an STD, pathogens in the birth canal can infect the fetus, causing neonatal morbidities such as gonorrhea, genital scars, and genital warts.

"Direct sexual contact is the main mode of transmission. Therefore, as long as the style of life is rigorous, and there is no extramarital sexual relationship, the way of contact in general interpersonal communication will not get sexually transmitted diseases. ”

"That'...... If I have a venereal disease, is there a cure? Niu Tiangou asked worriedly. Although he persuaded Zhang Dalong to be treated in a big hospital, he didn't know whether he could be cured or not.

"Of course there is a cure. In general, most patients with STDs can be cured as long as they are detected early and treated promptly and thoroughly.

"As far as I know about the treatment situation, penicillin can treat syphilis, broad-spectrum antibiotic lympsin can treat acute and chronic gonorrhea, doxycycline can treat gonorrhea and venereal lymphogranuloma and non-gonococcal urethritis, pioneer mycin can treat syphilis and gonorrhea, and some antiviral drugs can also be used to treat STDs infected by viruses such as simple scar virus, cytomegalocystis virus, infectious soft disgust virus, hepatitis B virus, and HIV.

"That brother of yours...... Oh, Zhang Dalong, hurry up and treat, it should be cured. ”

Hearing this, Niu Tiangou finally breathed a sigh of relief, and couldn't help muttering: "This kid always likes to run to the hair salon, and I told him a few times, but he just didn't listen, and this time it can be regarded as a lesson for him." ”

"Not only the ladies in the hair salon, but also those escort girls, prostitutes, drug addicts, multiple sexual partners, extramarital lovers, homosexuals and sexually transmitted diseases are all high-risk groups for sexually transmitted diseases, and you have to pay more attention to them in the future."

Speaking of this, Dr. Xue Lian stared at him meaningfully, "Drug treatment is just a last resort', and only by cleaning oneself can one not invade all poisons." ”

Niu Tiangou was stared at by her, and hurriedly changed the topic and said, "That...... Where did these STDs first come from? It can't be that the ladies were brought from their mother's womb as soon as they were born, right? ”

"This ...... It's really hard to explain. Dr. Xue Lian was stunned for a moment when asked, and then said after a little thought, "However, scientists have put forward several hypotheses about the origin of the STD virus.

"One is the theory of nature. This theory is that the STD virus evolved naturally and infected humans by chance, and the most popular theory is that the virus originated from chimpanzees in Africa.

"The other is the source of medicine. This theory suggests that humans used contaminated chimpanzee organ tissue in the production of the polio vaccine and infected humans at the time of vaccination.

"There is also a kind of artificial. Some believe that the STD is a catastrophe caused by genetic engineering, while others believe that it is the dregs of the Nazis or the product of some mad scientist's attempt to commit genocide and establish a 'new world order'.

"In short, scientists do not agree on their views. Where exactly did the STD virus originate? How exactly do humans get infected? So far, no one can say for sure. ”

"That'...... Why are ladies more susceptible to infection? Niu Tiangou asked again.

"The high infection rate among young ladies is due to the fact that they specialize in sexual services and have sex with too many men...... Let me tell you, if each man has a virus, this virus may not cause great harm to the human body, but ten men may have ten viruses, and a hundred men may have a hundred viruses, and these viruses will largely include STD viruses, so the chaotic sexual relationship makes the ladies have a high rate of 'winning' STDs.

"Moreover, even if there are no STDs among these viruses, so many viruses converge and fuse, and it is very likely that new and complex viruses will mutate and destroy the body's immune function.

"Do you think, if a young lady has dozens or hundreds of viruses in her body, and she is constantly cross-infected and mutates into new viruses, can she not suffer from messy diseases?"

Seeing that Niu Tiangou was stunned when he heard this, Dr. Xue Lian smiled faintly and asked, "Have you ever seen the spittoon in the ward?" ”

"......" Niu Tiangou glanced at her strangely, didn't react for a while, didn't know what she was going to say, "I've seen it, isn't it all used by patients to spit." ”

Niu Tiangou couldn't help but feel sick when he thought of the milky white, grayish-yellow, dark green, and even red and black thick phlegm in the spittoon in the ward, which were slimy.

Dr. Xue Lian continued, "Do you know how many bacteria are in a patient's sputum? Tens of millions! It contains thousands of viruses. If you ask a patient to spit thick phlegm on a piece of paper and put it under a microscope, you'll see thousands of bacteria and viruses swimming through the sputum!

"Because the sputum contains protein, the sputum spit out by the patient is equivalent to a 'culture medium' for bacteria and viruses, such as Escherichia coli, staphylococcus, Streptococcus pneumoniae, coronavirus, parainfluenza virus, respiratory syncytial virus, Mycoplasma pneumoniae, Mycobacterium tuberculosis, pertussis, Haemophilus influenzae, and so on.

"Some bacteria are very resistant to the outside world, for example, staphylococci can withstand drying for months, heat to 80 degrees Celsius, and it takes 30 minutes to be killed; Streptococcus pneumoniae can survive for one to two months in dry sputum without direct sunlight; Mycobacterium tuberculosis can survive for 6 to 8 months in dry sputum and remain contaminated for 8 to 10 days when adhered to dust; Coronaviruses can survive in phlegm for more than 30 hours.

"There are many diseases transmitted through sputum, such as infectious ** pneumonia, tuberculosis, influenza, cholera, measles, etc."

Hearing this, Niu Tiangou couldn't help but open his mouth wide. Nima, no wonder urban public places do not allow spitting, unlike the countryside, where you can spit on the ground casually with a "poof", and then drift away with the wind and dust to pollute the air.

"Then why does phlegm still have various colors?" After staying for a while, Niu Tiangou asked with some curiosity.

Seeing that he was so curious, Dr. Xue Lian explained: "Phlegm is a secretion of the respiratory tract, and healthy people generally do not have phlegm, even if there is a little, it is clear. However, if you have a respiratory disease and are infected by pathogenic microorganisms, you will produce a large amount of sputum, and bacteria and viruses will be trapped in the sputum. The color of the sputum is related to the condition. ”
