HIV Invades CD4+ Cells
HIV is a virus that invades CD4+ cells, which are a critical part of our immune system. Once inside a CD4+ cell, the virus uses the cell to create more virus. In the process HIV destroys the original cell.

As more and more immune system cells are destroyed, the body has a harder time fighting off both HIV and other illnesses. Illnesses that would not affect people with healthy immune systems take this opportunity to establish themselves. They are called opportunistic infections and conditions. Pneumocystis carinii pneumonia is an example of an opportunistic infection.
