AIDS, medical full name as "acquired immunodeficiency syndrome" (Acquired Immune Deficiency Syndrome--AIDS), the body is infected with human immunodeficiency virus (HIV), also known as AIDS virus as a result of infectious diseases. Popular, AIDS is the body's immune system is AIDS viruses, makes the threatening various pathogens lost resistance to occur in a variety of infection or tumors, finally led to the death of a serious infectious disease. This virus infected for life, the destruction of human immune system, making the human body loses the ability to resist diseases. When the HIV-infected immune function by viruses of serious damage to, or cannot maintain the lowest resistance, infected will develop as AIDS patients. As the human body immunity of lower, people will become more and more frequent infections on various pathogenic microorganisms, and the extent of the infection are also becoming more and more serious, and there will be for a variety of complex infection causing death. AIDS primarily through blood, improper sexual behaviour, drug abuse and mother-to-child transmission of genetic approaches to four. The international medical community has no effective drugs against AIDS and therapy. Thus, AIDS is also called "Super cancer" and "century killers".
AIDS virus called HIV, is a way to attack the body's immune system. The human immune system is the most important T4 lymphocytes as a target, a large number of phagocytosis, destruction of T4 lymphocytes, which breaking people's immune systems, and ultimately make the immune system crashes, makes lose on a variety of disease resistance and morbidity and mortality. Scientists turn this virus is called "human immunodeficiency virus". AIDS virus in the body of the average incubation period of 12 to 13 years. In the development of AIDS patients previously appearance looks normal, they can have no symptoms and living and working for many years, they can transmit the virus to others.
AIDS virus on the outside environment resistance is low, leaving the body, can survive only at room temperature for several hours to several days. High temperature, drying and disinfectants can kill the virus. Although there is currently no effective preventive AIDS vaccine, but have used a variety of clinical treatment of the antiviral drug effective in inhibiting HIV virus in the human body, to a large extent alleviate AIDS patient's symptoms and extend patients ' lives.
Since the United States in 1981, diagnosed since the first cases of AIDS and HIV in the world-wide spread at an alarming rate. According to UNAIDS and who in November 2004, announced in the 2004 AIDS epidemic report statistics show that the number of AIDS infection in the World 2004, breakthrough 3900 million new infections 490 000 and 300 000 patients died in 2004. Sub-Saharan region remains the most serious of AIDS infection, the infection rate in more than 25 per cent, the nine countries of the region's average life expectancy, or less than 40 years ago. The disease is not only in drug users, sex workers and other high-risk populations spread also has spread to the general population. In 2003, the region has a total of 300 000 new cases of infection, 220 000 people died because of AIDS. Currently, only 10 per cent of the global population of sub-Saharan Africa have 2500 million people living with HIV, accounting for 70% of the global total. Reports that have many population of Asia currently in control of the key moments of the spread of AIDS. On the one hand, the majority of countries in Asia the number of HIV carriers not to 1 per cent of the total population, the spread of the virus is still mainly limited to high-risk groups; on the other hand, the region has become the spread of diseases, one of the fastest growing areas, the current global one-quarter of the new cases occur in Asia. In 2003, the Asian region has a total of 110 million people were infected, 50 million people died of AIDS, the region now has a total of 740 million people living with HIV. In addition, in the Middle East, North Africa and Eastern Europe and other regions, and no signs of slowing the spread of the disease. In Europe, America and other high income countries with antiretroviral therapy, AIDS mortality has fallen into disrepute. But since some people guard, involved in drug abuse, pornography, same-sex sexual intercourse, and other transactions in high-risk behavior, many developed countries the number of newly infected and rebound. According to the United States United States Center for disease control estimate that average annual new HIV infections, and around 4 million people across the United States with a total of about $ 85 million to 95 million (December 2003). In the Caribbean region, AIDS has become a 15-year-old to 44-year-old age group of the leading causes of death; in North America, women infections on the rise. HIV/AIDS (UNAIDS) released on November 23, 2004 report on the global AIDS epidemic shows that Latin America has 170 million people infected with AIDS, infections on the rise. Recent years Latin America 9.5 million people died of AIDS, 24 million people infected with HIV.
AIDS-South Africa unbearable pain
China in 1985 the first cases of AIDS infections. 1 December 2003, the Ministry of health in China and the United Nations theme group on HIV/AIDS China jointly issued by the China AIDS joint assessment report show that the Chinese currently have HIV about 84 million, of which AIDS patients about 8 million cases, distributed in all provinces, autonomous regions and municipalities, covering all segments of society. In November 2003, Hong Kong SAR Government Health Department, Hong Kong has found 2172 people affected by the AIDS virus infection.
From 1985 to the end of the 15 years 2000, China reported incidence and deaths respectively 880 patients and 496 cases, whereas in 2001 and 2002, two-year total for the report's AIDS incidence and deaths respectively 1742 cases and 716 cases, 2002 annual report on the number of AIDS cases than the increase of 44 per cent in 2001.
