The Immune System
• A healthy individual has approximately 1,200 T-cells
• A T-cell is like a “soldier cell”. They go out and attack the bacteria or virus.
• The immune system then forms anti-bodies to protect you.

HIV and the Immune System
• When the HIV virus attacks the body. The virus takes over the T-cells and makes them HIV factories.
• T-cell count decreases and the HIV viral load increases.
• HIV antibodies appear 3 weeks to 6 months after infection.
• When the individuals T-cell count drops below 200, an AIDS diagnosis is given.
• Once you are given an AIDS diagnosis, it does not change. Regardless of your T-cell count.
• The virus is the same…the only thing that has changed is the number of T-cells.
