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

4
T Cells

• T cells circulate in your body looking for cells
  that dont 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)

5
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

6
AIDS

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