AIDS or Acquired Immuno Deficiency Syndrome is a disease which reduces the ability of the infected person to fight other diseases. HIV or Human Immuno Deficiency Virus causes AIDS. This disease is transmitted through blood or other body fluids. People get infected while sharing needles or while having unprotected sex with an infected person. An unborn child can be infected by its HIV positive mother.
