AIDs :: Free AIDS Essays
                    A.I.D.S      Acquired Immune Deficiency Syndrome      A.I.D.S., also known as Acquired Immune Deficiency Syndrome, is a disorder of the body’s immune system. In A.I.D.S. the body stops producing some of its important natural defenses against disease. Victims often die from disease of infections they cannot fight. A.I.D.S is the result of an infection known as HIV, human immunodeficiency virus. A person with HIV gradually loses function of their immune system, becoming less able to fight off common colds and virus, thus eventually leading to death.      HIV was first revealed in the early 80’s in homosexual men. Infection with HIV does not necessarily mean that a person does have A.I.D.S. A person can be HIV positive for years without developing illnesses that are associated with the A.I.D.S. disease. HIV is characterized by a gradual deterioration of the immune system. Cells known as T-Helper cells are disabled and killed during the course of the infection. These cells play an important part in the human body because they signal other cells to perform their special functions.      The AIDS epidemic is growing very rapidly among minority populations and is a leading killer of African American males.      HIV can be transmitted by contact with infected blood, most often by the sharing of drug needles or syringes contaminated with blood containing the virus. The risk of contacting the HIV virus from blood transfusions has decreased since earlier years. Now all donated blood is screened for any signs of the HIV virus. HIV is spread most commonly by having sex with someone who already has the virus. The virus can enter the human body through the lining of the vagina, vulva, penis, rectum, or mouth during sex.      Almost all HIV infected children get the HIV virus from their mothers before or during birth. A drug known as AZT can reduce risk of transmission of the virus from mother to child. The virus can also be transmitted when an HIV infected mother nurses her child with infected milk.      Once HIV enters the body it infects many cell and replicates itself rapidly. Two to four weeks after the person is infected with the virus, they begin to suffer flu-like symptoms. HIV also is spread through contact with infected blood. Before blood was screened for evidence of HIV infection and before heat-treating techniques to destroy HIV in blood products were introduced, HIV was transmitted through transfusions of contaminated blood.          Laboratory studies reveal that saliva has natural properties that limit the power of HIV to infect. Research studies of people infected with HIV have found no evidence that the virus is spread to others through saliva such as by kissing.
