19. 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.

20. 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.
