What is AIDS (AIDS)? Answer: AIDS is the phonetic translation of AIDS, which stands for Acquired Immune Deficiency Syndrome.
The full medical name for AIDS is Acquired Immunodeficiency Syndrome. AIDS is a worldwide, fatal infectious disease.
This name expresses the complete concept of AIDS, from which we can learn three clear definitions of AIDS: (1) Acquired: indicates that the cause of the disease is acquired rather than congenital, AIDS is an infectious disease caused by a retrovirus, also known as HIV. It is mainly transmitted through sexual contact, drug use, and perinatal transmission.
(2) Immunodeficiency: In terms of pathogenesis, it is mainly caused by damage to the human immune system, leading to a decrease in the protective function of the immune system and loss. (3) Syndromes: These are complex groups of symptoms that occur as a result of opportunistic infections and tumors in various systems caused by immunodeficiency.
It is also commonly referred to as AIDS. What year was AIDS discovered? AIDS was discovered in 1981 and officially named "Acquired Immune Deficiency Syndrome" in 1982.
The virus that causes "human acquired immunodeficiency syndrome" was discovered in 1983. The now widely used name "human immunodeficiency virus" is a term that was standardized in 1996 by the International Society for Microbiology and the Society for Taxonomy of Viruses.
What is HIV? HIV stands for human immunodeficiency virus. It is a virus that lives in the human bloodstream and attacks the human immune system.
It targets T4 lymphocytes, which are the most important cells in the human immune system, and devours and destroys them in large quantities, thus destroying the entire human immune system, and ultimately the body loses the ability to resist various diseases, leading to death. Scientists call this virus "human immunodeficiency virus".
Below are photos (left) and models (right) of HIV. How can women protect themselves? ①Take the initiative to learn about AIDS and how to prevent it.
② Be clean and have sex with your only regular partner. ③To persuade their spouses or sexual partners to understand AIDS, in order to protect them from HIV infection, to protect them is to protect themselves.
④Know your sexual partner's life background and habits well, and if you have any suspicion, refuse to have sexual contact with him or insist on using condoms. ⑤ Never use syringes and needles with a person***.
What are the three conditions that must be present simultaneously for HIV to spread? ① A large amount of virus is excreted from the body of the infected person. ① A large amount of virus is excreted from the infected person's body. ② The excreted virus has to be passed on to others in some way.
③ A sufficient amount of virus enters the body. What are the ways of spreading AIDS? Experiments have proved that the blood, ***, *** secretions, and breast milk of HIV-infected people carry HIV.
Therefore, it can be seen that HIV is transmitted through sexual contact, blood, mother and child (perinatal), and breastfeeding. What are the main modes of transmission of HIV? In the early days of the epidemic, it was first recognized that most HIV infections were among homosexuals.
However, as the AIDS epidemic progressed and epidemiologic investigations continued, it was found that due to the size of the heterosexual population, HIV transmission among heterosexuals has become the dominant mode of transmission today, accounting for 70% of all infections worldwide. How does HIV infection in women differ from that in men? Female homosexuality is often not associated with HIV because lesbians *** tend to be 1:1 and rarely exchange bodily fluids with each other.
Women are more likely to be infected with HIV than men, and it is generally recognized that transmission from men to women through sexual contact is 2-4 times more likely than transmission from women to men. Can social contact transmit HIV? HIV is occasionally present in other body fluids, such as tears, saliva and sweat, but is generally present in small enough quantities to cause HIV transmission.
Therefore, occasional contact in social situations, such as shaking hands, communal fixtures or bathrooms, eating together, sneezing, hugging, and courtesy kissing, generally does not transmit HIV. Can mosquitoes transmit HIV? According to research, HIV neither develops nor reproduces in mosquitoes, so it cannot be transmitted biologically.
And mechanical transmission is not feasible in mosquitoes. This is because, before sucking blood, the mosquito first spits out saliva from the salivary duct (as its lubricant in order to suck blood), and then inhales blood from the esophagus, which is unidirectional, and does not spit it out again after inhalation.
In addition, the blood remaining on the mosquito's mouth, because it is only 0.00004 milliliters, has to bite repeatedly for 2800 times before it can cause HIV infection. Moreover, even if a mosquito inhales blood with HIV, HIV can be digested and destroyed by the mosquito within 2 to 3 days and disappear completely.
According to the physiological characteristics of mosquitoes, once a mosquito has sucked enough blood, it will only bite again after complete digestion. At present, the world has not found mosquitoes or insect bites infected with AIDS reports.
So you don't have to worry about mosquitoes spreading hepatitis B and AIDS. Can saliva transmit HIV? HIV can be found in saliva, but the amount of virus in saliva is very small.
It takes a certain amount of HIV to cause transmission. It has been calculated that it would take more than 20 milliliters of saliva from an infected person to reach an infectious level of the virus in saliva.
In addition, U.S. scientists have found that there is a "secretory leukocyte inhibitory protease" protein in human saliva, which can effectively inhibit HIV infection of human immune cells in the test tube, so the general kissing, *** with the meal, coughing or sneezing are unlikely to be infected with HIV. There are no cases of infection through saliva in the current report.
But a passionate kiss accompanied by bleeding or ulcers on the gums of the infected person's mouth; *** when the infected person's *** is discharged into the mouth of a healthy person, there is a possibility of HIV transmission through the mucous membranes of the oral cavity into the bloodstream. What are the risk factors for HIV? Homosexuality; multiple ***; unprotected penetrative ***; coexisting sexually transmitted diseases; intravenous drug use; and blood transfusion transmission.
Trends in the AIDS epidemic? Since AIDS was first identified in the United States in 1981, it has spread around the world at an unusually rapid rate, with few countries immune. By the end of 1999, there were 49.9 million people living with HIV and AIDS, including 45.1 million adults, and 21% of them were women.
2. How to prevent AIDS
For personal prevention, in addition to acquiring knowledge of AIDS, it is important to do the following: (1) be clean, do not go to illegal blood collection centers to sell blood, do not get involved in pornography, and do not rashly enter or leave certain entertainment venues; (2) do not use the Internet or other means of communication; and (3) do not use the Internet or other means of communication. The first thing you need to do is to get a good deal of information about the company's products and services, and then you can get a good deal of information about the company's products and services, and then you can get a good deal of information about the company's products and services.
(2) When you are sick, you should go to regular clinics and hospitals for treatment, pay attention to the safety of blood transfusion, and do not go to medical institutions where the sterilization of medical equipment is unreliable, especially individual clinics for injections, tooth extraction, acupuncture, and surgery. You don't have to use unsterilized equipment for ear piercing, tattooing, and cosmetic surgery.
(3) not with others *** enjoy razor, toothbrush, etc., try to avoid contact with other people's bodily fluids, blood, contaminated by other people's items to be promptly disinfected. (4) pay attention to the contact with AIDS patients: to AIDS patients blood collection and injection, syringes should be used disposable supplies, the patient's blood, excreta, contaminated items should be thoroughly incinerated.
The patient's utensils and medical instruments should be used exclusively, such as the patient's razor, toothbrush, towel, teacups, etc. should be used exclusively, and hand-washing with soap after urination and defecation can be used to achieve the purpose of disinfection. HIV-positive people should be prohibited from donating blood and providing other body fluids.
Women with AIDS should be told not to feed their babies mouth-to-mouth; menstrual period should be handled especially well menstrual blood, which should not be allowed to contaminate other things; and condoms should be used during sex to prevent infection of others. At the same time, try to persuade the patient not to get pregnant, because pregnancy can transmit HIV to offspring.
The patient's ***, the spouse should be regular HIV antibody test; the other members of the family of the antibody-positive person, in the conditions of the region should also be HIV test.
All in all, AIDS is an incurable disease, but it can be prevented.
The most important thing is to abide by the ZF decree, abide by sexual morality, and pay special attention to the illegal black blood stations - no matter how poor you are, you can't go to sell your blood, and no matter how urgent you are, you can't transfuse the blood that may be contaminated with HIV, so as not to be infected with HIV. If there is a suspicion of HIV infection, you can go to the local medical research institutions, large hospitals, provincial and municipal epidemic prevention institutions to receive a checkup; a blood draw HIV antibody negative, can not be completely ruled out that there is no infection of AIDS, should be checked regularly.
3. Q&A about AIDS prevention
1AIDS is a serious infectious disease with a high mortality rate, and there is no cure for it, but it can be prevented.
2. AIDS is mainly transmitted through sexual contact, blood and mother-to-child transmission. 3, and AIDS patients and HIV-infected people's daily life and work contact will not be infected with AIDS.
4, cleanliness and sexual morality are the fundamental measures to prevent sexual transmission of AIDS. 5, the correct use of condoms can not only contraception, but also reduce the risk of infection of AIDS, sexually transmitted diseases.
6, early treatment and cure of STDs can reduce the risk of infection of AIDS. 7, *** drug use with syringes is an important way to spread AIDS, so we should refuse drugs and cherish life.
8, avoid unnecessary blood transfusions and injections, use blood and blood products tested for HIV antibodies. 9, care, help and non-discrimination of AIDS patients and HIV-infected people is an important aspect of the prevention and control of AIDS.
10. AIDS threatens every person and every family, and prevention of AIDS is the responsibility of the whole society.
4. Knowledge of AIDS prevention in safety education
Knowledge of AIDS prevention in safety education is divided into four points by Insight:
(1) Be clean, do not go to illegal blood collection stations to sell blood, do not get involved in pornographic places, and do not go in and out of certain places of entertainment recklessly; maintain a strong sense of prevention of AIDS on all occasions; do not have any fluke; and do not try drugs out of curiosity. and try to take drugs.
(2) When you are sick, you should go to regular clinics and hospitals for treatment, pay attention to the safety of blood transfusion, and do not go to medical institutions where the sterilization of medical equipment is unreliable, especially individual clinics for injections, tooth extraction, acupuncture, and surgeries. The company's main goal is to provide the best possible service to its customers.
(3) not with others *** enjoy razor, toothbrush, etc., try to avoid contact with other people's bodily fluids, blood, contaminated by other people's items to be promptly disinfected.
(4) pay attention to the contact with AIDS patients: to AIDS patients blood collection and injection, syringes should be used disposable supplies, the patient's blood, feces, contaminated items should be thoroughly incinerated. The patient's utensils and medical instruments should be used exclusively, such as the patient's razor, toothbrush, towel, tea cups, etc. should be used exclusively, urination, defecation should be washed with soap after the disinfection can be achieved.
5. What is the basic knowledge of AIDS prevention
AIDS (AIDS) is known as Acquired Immune Deficiency Syndrome. It is caused by the AIDS virus (HIV), an infectious disease for which there is no vaccine, no effective cure and a very high mortality rate. By severely damaging the immune system, HIV causes extremely low resistance and ultimately leads to generalized exhaustion and death.
AIDS has entered a period of rapid growth in some areas, such as India, Thailand, if not prevented, may be in the near future and Hepatitis B as common, many provinces and cities in our country have been found in AIDS patients and AIDS carriers, which should cause us to pay great attention.
AIDS (AIDS) is mainly transmitted through blood, ***, *** secretions, breast milk and other body fluids. There are three proven ways of transmission:
1. Sexual transmission: through heterosexual or homosexual sex.
2, blood transmission: through *** injecting drugs with unsterilized syringes and needles, importing HIV-containing blood or blood products, using unsterilized or poorly sterilized medical devices (such as needles, acupuncture needles, dental equipment, cosmetic equipment, etc.), *** razors and toothbrushes, etc. Transmission.
3, mother-to-child transmission: through the placenta, birth canal and breastfeeding transmission.
AIDS is not transmitted through the air, diet (water), through general daily contact in public **** places (such as: shaking hands, seats in public **** places, toilets, bathtubs, etc.), through banknotes, coins, tickets and mosquito bites, and swimming pools.
Although AIDS is an extremely dangerous infectious disease, it is completely preventable for individuals, and its main preventive measures are:
1, abide by the law and morality, cleanliness, against premarital sex, against sexual promiscuity.
2, do not engage in prostitution, prostitution and other illegal activities.
3. Do not use drugs in any way and stay away from drugs.
4. Do not use untested blood products and reduce unnecessary blood transfusions.
5. Do not go to medical institutions that are not strictly sterilized for injections, tooth extraction, acupuncture, cosmetic treatment or surgery.
6, not *** with toothbrushes, shaving (shaving) razor.
7, to avoid the blood of the injured in daily work, life.
8, according to foreign experience, the correct use of condoms can help to avoid infection of AIDS.
9, suffering from sexually transmitted diseases should be timely and active treatment, otherwise the existing lesions will increase the risk of HIV infection.
