HIV infection process AIDS medicine is called "acquired immunodeficiency syndrome" (Acquired Immune Deficiency Syndrome - AIDS), by the human immunodeficiency virus (HIV, also known as the AIDS virus) cause. Tongsudejiang, AIDS is the body's immune system to destroy HIV was, so that the body of a variety of life-threatening loss of resistance to pathogens, which occurred in a variety of tumor or infection, resulting in the death of a serious infectious disease. Transmission of the virus for life, destruction of the human immune system so that the loss of human resistance to various diseases. When the HIV virus by the immune function of severely damaged, and can not maintain a minimum capacity of the disease, infected people will develop into AIDS patients. With the human body's immune system to reduce, people will more and more frequently infected with a variety of pathogenic micro-organisms, but also the extent of infection is becoming increasingly serious, and there will be complex due to a variety of infections and deaths. HIV, including the main route of transmission of blood, sexual contact and maternal genetic and so on. AIDS is still incurable disease. HIV infection process Referred to as the AIDS virus HIV, a human immune system to attack the virus. It is the body's immune system to the most important T4 cells as a target, a large number of swallow, T4 cell damage in order to break the human immune system, so that the final collapse of the immune system so that the human body as a result of loss of resistance to various diseases and disease And death. Scientists to the virus called "human immunodeficiency virus." AIDS virus in the body of the average incubation period of 12 years to 13 years. In developed into AIDS patients looked normal before the appearance, they can not have any symptoms to live and work for many years, we will be able to spread the virus to others. AIDS clinic is divided into 3: 1. HIV infection. Patients infected with AIDS virus have no symptoms, only the blood of HIV-positive test results; 2. AIDS-related syndrome. Patients other than the groin lymph nodes for more than two unexplained swollen lymph nodes and continued for more than 3 months, at the same time general symptoms like fever, fatigue, loss of appetite, weight loss and diarrhea; 3. AIDS stage. The patient is to highlight the performance of the pathogenic infection, the incidence of malignant tumors, and can not find the reasons for the cellular immune deficiencies. HIV resistance to the external environment is weak, leaving the human body, the room temperature can only survive a few hours to several days. High temperature, dry, as well as common disinfectants can kill the virus. Although there is no effective vaccine to prevent AIDS, but there has been for the clinical treatment of a variety of anti-viral drugs are effective in inhibiting the body of the HIV virus replication, to a large extent alleviate the symptoms of AIDS patients and prolong life. Since 1981, U.S. researchers found the first case of AIDS cases in the world, AIDS on a global scale spread rapidly emerging as the world's attention to an important public health and social issues. In June 2001, the United Nations General Assembly Special Session on AIDS adopted the "AIDS", AIDS prevention and control of the international community for action to formulate a unified goals and action plans to achieve by the year 2015 to halt and begin reversing the spread of AIDS Trend The overall objective. In July 2008, UNAIDS published the "2008 global AIDS epidemic report," pointed out that after many years of the international community to combat AIDS and make positive efforts to combat the global AIDS in 2007 for the first time there have been "marked significant progress "New HIV infections and deaths have declined. The report shows that in 2007 new HIV-infected people at 250 million, down from 1998's 3,200,000 people; in 2007 about 200 million people died of AIDS, more than 200,000 young people in 2001. However, the global spread of the AIDS epidemic trend has not been reversed. According to UNAIDS statistics, a total of 33,200,000 worldwide infected with HIV, of which 22,500,000 infected people in sub-Saharan Africa many countries; Asia have infected nearly 5,000,000; Eastern Europe and Central Asia about 1,500,000; Latin America, about 1,700,000; North America, Western Europe and in Central and Eastern Europe, about 2,000,000, of which about U.S. 1,200,000.
