Quick Answer
AIDS is the advanced stage of HIV infection, defined by a severely damaged immune system or the presence of certain opportunistic infections. HIV is the virus that causes AIDS, but with modern treatment, most people with HIV never develop AIDS. Undetectable viral load means the virus is untransmittable.
- HIV is a retrovirus that attacks CD4 cells, weakening the immune system.
- AIDS is diagnosed when CD4 count drops below 200 or an opportunistic infection occurs.
- With antiretroviral therapy, HIV can be managed to undetectable levels.
- Undetectable equals untransmittable (U=U) under current guidelines.
- HIV and AIDS are not the same; AIDS is the late stage of HIV.
- Early testing and treatment prevent progression to AIDS.

Understanding the difference between HIV and AIDS is key to grasping how the disease works and why treatment matters. HIV (human immunodeficiency virus) is a retrovirus that infects and destroys CD4 cells, which are crucial for immune defense. Over time, without treatment, the immune system becomes too weak to fight off infections, leading to AIDS (acquired immunodeficiency syndrome). However, modern antiretroviral therapy can suppress the virus to undetectable levels, allowing people with HIV to live long, healthy lives and preventing transmission to others. This guide clarifies the definitions and classifications used by health experts.
