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 Tcell 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.
