    Science Says | What HIV Does to Your Immune System — The CD4 Story

    HIV doesn't announce itself. It works silently — targeting a specific type of immune cell called a CD4 T-cell. These are the cells your body depends on to fight infection. As HIV destroys CD4 cells over time, the immune system weakens. When the CD4 count drops below 200 cells per cubic millimetre, the body can no longer defend itself. That is the clinical threshold between HIV and AIDS. The good news: with modern antiretroviral treatment, most people living with HIV keep their CD4 count well above that threshold — and live full, healthy lives.
