Teaching process
1. What is AIDS?
The full medical name of AIDS is "Acquired Immune Deficiency Syndrome" (English abbreviation AIDS). A serious infectious disease caused by the AIDS virus (Human Immunodeficiency Virus - HIV). After HIV invades the human body, it destroys the body's immune function, causing the body to develop a variety of infections and tumors that are difficult to cure, eventually leading to death.
HIV antibodies can only be detected in the blood 4 weeks to 3 months after infection with HIV, but you are already infectious before the antibodies are detected. The blood, semen, vaginal secretions, breast milk, and wound exudates of HIV-infected people contain a large amount of HIV and are highly contagious.
It takes an average of 7-10 years (incubation period) for people infected with HIV to develop into AIDS patients. People who appear normal before becoming AIDS patients can live and work without symptoms for many years but can transmit the virus to others.
Adolescents are at great risk. About 70% of HIV-infected people worldwide are young adults aged 15-39. Adolescents in the stage of sexual development are the main victims; female adolescents are particularly susceptible. AIDS is all around us; AIDS prevention work cannot wait and we should take action now.
2. Current status of the AIDS epidemic
Today, 20 years after the first clinical case of acquired immunodeficiency syndrome was reported, AIDS has become the most devastating disease ever experienced by mankind. disease. Since the AIDS epidemic began, more than 60 million people have been infected with the virus. AIDS is currently the leading cause of death in sub-Saharan Africa. Globally, it is the fourth leading killer.
Since the first case of AIDS was discovered in my country, the epidemic has continued to rise. At the beginning of the epidemic, the growth rate of AIDS was slow. Within eight years of 1993, the cumulative number of HIV-infected people reached 10,000. Subsequently, the epidemic gradually accelerated, and in just two years in 1995, the cumulative number of infections reached 100,000. In the next five years, the number of people infected with HIV in my country will increase by 100,000 per year. From 2000 to 2001, the number increased by 150,000 to 850,000. By the end of June 2002, the cumulative number of people infected with HIV had reached 1 million.
It can be seen from the above data that AIDS has spread rapidly and widely around the world, and has become a public health and social hot issue that attracts worldwide attention. It is closely related to human behavior and greatly damages family and social productivity.
AIDS is an infectious disease that currently has no effective cure and a very high mortality rate, but it is a serious infectious disease that is completely preventable. Informing everyone about prevention knowledge through publicity and education and improving self-protection capabilities are currently one of the most effective ways to prevent and control AIDS.
3. The transmission route of AIDS
HIV mainly exists in the body fluids of HIV-infected people - AIDS patients, including blood, semen, vaginal secretions, and breast milk , wound exudate, etc. Any behavior that results in the exchange of body fluids has the potential to spread HIV. Epidemiological surveys have confirmed that HIV has three transmission routes: sexual contact, blood transmission, and mother-to-child transmission.
1. Sexual transmission: transmitted through heterosexual or same-sex sexual behavior.
2. Blood transmission:
a. Injecting drugs with non-sterile syringes or needles through vagina;
b. Transmitting HIV-containing HIV Blood or blood products;
c. Use of various medical instruments that are not sterilized or not strictly sterilized (such as needles, acupuncture needles, dental and beauty instruments, etc.); d. Shaving through surgery Transmitted by (shaving) knives and toothbrushes
3. Mother-to-child transmission: transmitted through the placenta, birth canal and breastfeeding.
4. The serious harm of AIDS
1. Although scientists around the world are researching day and night, no drug that can cure it has been found so far, nor can it effectively prevent its occurrence. of vaccines.
2. Once a person is infected with HIV, most people will get sick and die sooner or later.
3. The losses caused by AIDS are not limited to individuals, but also involve families, children, relatives and friends.
4. AIDS is not a simple disease problem, but a major social problem that threatens human survival and development. It has caused catastrophic impacts such as retarded social development, loss of labor force, sharp increase in medical expenses, and decline in social welfare levels, affecting the entire country and people.
5. Important measures to prevent AIDS
1. Do not disclose the names, addresses and personal privacy of patients and infected persons at will;
2. Do not disclose information at will Exaggerate their illness and living conditions, causing harm to the physical and mental health of them and their families;

8. Summary
1. AIDS is a serious infectious disease that currently has no effective cure but is completely preventable. Adolescents are the main victims of AIDS and are the key to preventing AIDS. new force. Teenagers should learn knowledge and skills about sexual health and prevention of HIV infection through formal channels. They should not be overly fearful and prejudiced about AIDS, nor should they ignore the alarming rate at which AIDS is spreading and the social harm it causes. sex.
I hope that all students can communicate the knowledge they have learned this time with their classmates, friends and family members, so as to arouse the whole society's attention to AIDS and a correct understanding of AIDS.
