Human immunodeficiency virus (HIV) is a lentivirus. HIV destroys cells in the body called CD4 T-cells. CD4 T-cells are a type of lymphocyte or a white blood cell. These are important cells that protect the body against various bacteria, viruses and other 'germs'. HIV actually multiplies within CD4 cells and cannot be destroyed by white blood cells because the virus keeps on changing its outer coat not allowing the white blood cells to fight the infection. HIV is transmitted through direct contact of mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, and breast milk. Once affected with HIV a person can then develop Acquired immune deficiency syndrome (AIDS). To develop AIDS a person usually has the HIV virus for several years developing infections and other AIDS-related problems. This is because it usually takes several years for the number of CD4 T-cells to reduce to a level where your immune system is weakened. Acquired immune deficiency syndrome (AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV). This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors. HIV is transmitted to 1000’s of individuals yearly and is still a growing concern for the United States since its first case in 1981. Since the first case in 1981 it is estimated that over 1.7 million people have been infected with HIV including over 600,000 who have already died. The Centers for Disease Control and Prevention estimated that there were approximately 50,000 people newly infected with HIV between 2006 and 2009 and 20% of the United States population that are unaware that they are infected. There are a number of state and federally funded programs to support the prevention of HIV/AIDS.
