what is AIDS
AIDS stands for Acquired Immune Deficiency Syndrome. It is not passed down from generation to generation through genes, but it is acquired. AIDS is a disease that attacks the immune system, a system that is vital in fighting off disease. This disease causes the immune system to be deficient, or weakened, so that it cannot properly fight off diseases because it is unable to produce white blood cells. AIDS is a syndrome or a group of illnesses with many possible symptoms that can occur together in a weakened condition. This disease is not localized in one specific area, its is found all over the world. (http://www.gmhc.org/basics/basics.html) AIDS is the most common and widespread deficiency disease known to mankind. It has already infected and killed millions of people worldwide. Its two viruses, named human immunodeficiency viruses (HIV-1 and HIV-2) are retroviruses that use RNA as its genetic material. When it invades a eukaryotic cell, a retrovirus "reverse transcribes" it's RNA into DNA, which then directs the synthesis of more viruses, using the transcription and translation machinery of the cell. The HIV virus weakens the immune system by infecting and destroying helper T-cells, which are mandato
AIDS is caused by the human immunodeficiency virus, or HIV. This virus attacks the antibodies in a person's immune system, thereby disabling the system. HIV uses the immune system to its advantage. Viruses cannot live unless they are inside of a living cell called a host. The virus uses the host cell to reproduce themselves, causing the cell to die in the process. The HIV virus attacks T4 lymphocytes, which are a special type of white blood cell. These cells are the body's method of defense. Without them, humans are susceptible to disease and infection. It is not HIV that kills people, but the infections that people get because of a weakened immune system. AIDS is spread in several different ways. One method of transmission is through sexual activity. This includes all forms of sex weather it be vaginal sex, anal sex, or oral sex. HIV can be transmitted through vaginal secretions in women to men by way of the bloodstream. In the same way, men can pass HIV to women in their semen. Men can also pass it to other men by way of bodily fluids if the men are bisexual or homosexual. The more sexual partners one has, the greater the risk of contracting HIV.
