Aids and HIV HIV stands for Human Immunodeficiency Virus It is the virus that causes AIDS HIV enters the body through the transmission of bodily fluids and attacks a specific type of immune cells called T Cells

T Cells T cells circulate in your body looking for cells that “don’t belong” They will attack and destroy invading bacterial cells and cancer cells When infected with HIV, the virus begins to reproduce within the T Cell (this destroys the T Cell)

The Onset of AIDS An infected person eventually reaches the point in which the body has too few T Cells to defend against invaders At this point the person has AIDS

AIDS AIDS stands for Acquired Immune Deficiency Syndrome AIDS is 100% fatal
