teaching process
First, what is AIDS?
The full medical name of AIDS is "acquired immunodeficiency syndrome" (AIDS for short), which is a serious infectious disease caused by -HIV. After HIV invades the human body, it destroys the immune function of the human body, causes various incurable infections and tumors, and eventually leads to death.
HIV antibody can not be detected from blood until 4 weeks to 3 months after HIV infection, but it is contagious before the antibody is detected. The blood, semen, vaginal secretions, milk and wound exudates of HIV-infected people contain a large number of HIV, which is highly contagious.
It takes an average of 7- 10 years for HIV-infected people to develop into AIDS patients. Before they became AIDS patients, they looked normal. They can live and work for many years without symptoms, but they can spread the virus to others.
The harm to teenagers is very serious. About 70% of HIV-infected people in the world are 15-39 years old. Teenagers in the stage of sexual development are the main victims; Female teenagers are particularly vulnerable. AIDS is around you; AIDS prevention can't wait, so we should act now.
Second, the epidemic situation of AIDS
Today, 20 years after the first clinical case of acquired immunodeficiency syndrome was reported, AIDS has become the most devastating disease that human beings have never seen. Since the AIDS epidemic, more than 60 million people have been infected with this virus. At present, AIDS is the leading cause of death in sub-Saharan Africa. Globally, it is the fourth biggest killer.
Since the first case of AIDS was discovered in China, the epidemic situation has continued to rise. At the beginning of the epidemic, the growth rate of AIDS was slow, and in the eight years from/kloc-0 to 993, the cumulative number of HIV-infected people reached 6.5438+0 million. Subsequently, the epidemic speed gradually accelerated, reaching 1995, only two years.
Suddenly, the cumulative number of infected people has reached 65438+ 10,000. In the next five years, the number of HIV-infected people in China will increase at a rate of 654.38+10,000 per year. From 2000 to 200 1, 1, it increased by1.50 thousand, reaching 850 thousand. By the end of June 2002, the cumulative number of people infected with AIDS had reached 1 10,000.
As can be seen from the above data, AIDS has spread rapidly and widely around the world, and has become a hot issue of public health and society that attracts worldwide attention. It is closely related to people's behavior and extremely destructive to family and social productivity.
AIDS is a serious infectious disease. There is no effective cure and the mortality rate is high, but it can be completely prevented. It is one of the most effective ways to prevent and control AIDS by telling everyone about prevention knowledge and improving self-protection ability through publicity and education.
Three. Transmission of AIDS
HIV mainly exists in the body fluids of AIDS patients infected with HIV, including blood, semen, vaginal secretions, milk, wound exudates and so on. Any behavior that can cause the exchange of body fluids may spread HIV. Epidemiological investigation confirmed that there are three ways of transmission of HIV: sexual contact, blood transmission and mother-to-child transmission.
1. Sexual transmission: transmission through heterosexual or homosexual sex.
2. Blood transmission:
A. Inject drugs through * * * with unsterilized syringes or needles;
B, by inputting blood or blood products containing HIV;
C use all kinds of medical instruments that are not disinfected or not strictly disinfected (such as needles, acupuncture needles, dental and beauty instruments, etc.). ); D, spread by using razors and toothbrushes.
3. Mother-to-child transmission: transmission through placenta, birth canal and breastfeeding.
Fourth, the serious harm of AIDS.
1. Although scientists all over the world are studying around the clock, so far, no medicine can be cured and no vaccine can effectively prevent it.
2. Once people are infected with HIV, most of them will get sick and die sooner or later.
The loss caused by AIDS is not limited to individuals, but also involves families, children and relatives and friends.
4. AIDS is not a simple disease problem, but a major social problem that endangers human survival and development. Its disastrous effects, such as slow social development, labor loss, sharp increase in medical expenses and decline in social welfare level, have affected the whole country and people.

Eight. abstract
1. AIDS is a serious infectious disease, and there is no effective treatment at present, which is completely preventable. Teenagers are the main victims of AIDS and the new force to prevent AIDS. Teenagers and friends should learn knowledge and skills about sexual health and prevention of AIDS infection through formal channels. They should not have excessive fear and prejudice against AIDS, nor should they ignore the alarming spread of AIDS and its social harm. I hope that all students will share what they have learned with their classmates, friends and family around them, so as to arouse the attention of the whole society and a correct understanding of AIDS.
Nine, recite the "prevention of AIDS-three-character classics"
AIDS is a terminal disease. If you are infected, you will die. Although this disease is dangerous, please don't be surprised. To prevent it, you must remember it clearly.
No whoring, no drug addiction. Teenagers value virginity, and they should cherish themselves before marriage.
Good couples are loyal, avoid promiscuity and detached feelings. Know how to love yourself, be honest, do well and keep peace!
