At present, the difficulties of AIDS prevention education in colleges and universities include: sex education in colleges and universities is in the state of making up lessons, sex values education is relatively insufficient, and attitudes and skills to prevent AIDS need to be improved.

AIDS, that is, acquired immune deficiency syndrome, English name acquired immune deficiency syndrome, AIDS. It is a syndrome that human beings are infected with human immunodeficiency virus, leading to immune deficiency, a series of opportunistic infections and tumors, and even death in severe cases. 1983, human beings first discovered HIV.

At present, AIDS has become a public health problem that seriously threatens the health of people all over the world. It targets T4 lymphocytes, which are the most important in the human immune system, devours and destroys T4 lymphocytes in large quantities, thus destroying the human immune system and finally causing it to collapse, leading to illness and death due to the loss of resistance to various diseases.

Influenza-like or serum-like symptoms may appear at the initial stage of infection, then enter a long asymptomatic infection period, then develop into the pre-acquired immune deficiency syndrome, and finally various serious opportunistic infections and malignant tumors appear, which becomes acquired immune deficiency syndrome. Scientists call this virus human immunodeficiency virus.

The average incubation period of HIV in human body is 12 to 13 years. Before they develop into AIDS patients, they look normal. They can live and work for many years without any symptoms. 65438+February 1 is World AIDS Day every year. So far, there is no effective means to prevent and treat AIDS, and there are few successful cases, so it is called super cancer.

Pathogenesis of AIDS:

1, primary infection

HIV needs to enter the cell through receptors on the surface of susceptible cells, including the first receptor and the second receptor. After HIV enters the human body, it reaches the local lymph nodes within 24-48 hours, and the virus components can be detected in the peripheral blood in about 5 days. Viremia followed, leading to acute infection.

2. The process of HIV infecting human cells.

Adsorption and permeation: After HIV- 1 infects human body, it selectively adsorbs on CD4 receptor of target cell and enters host cell with the help of helper receptor. After cyclization integration, transcription and translation, assembly, maturation and budding, mature virus particles are formed.

3. Three clinical outcomes after 3.HIV infection.

Because the body's immune system can't completely destroy the virus, it forms chronic infection, which can be manifested as three clinical outcomes: typical progressor, rapid progressor and long-term non-progressor.
