Quick Answer
Human immunodeficiency virus (HIV) is a virus that attacks the immune system, specifically CD4 cells (T cells), weakening the body's ability to fight infections. Without treatment, HIV can progress to AIDS, the most advanced stage. Modern antiretroviral therapy (ART) can suppress the virus to undetectable levels, allowing people to live long, healthy lives.
- HIV is a retrovirus that inserts its genetic material into human cells.
- HIV is transmitted through blood, semen, vaginal fluids, and breast milk.
- Untreated HIV can lead to AIDS, a severe immune deficiency.
- With ART, viral load can become undetectable, meaning HIV cannot be transmitted sexually.
- HIV is not spread by casual contact, air, water, or insect bites.
- Early testing and treatment greatly improve long-term health outcomes.
Context Most Pages Skip
HIV stands for human immunodeficiency virus. The name describes exactly what it does: it infects humans, causes immune deficiency by destroying key immune cells, and is a virus, meaning it replicates inside host cells. Understanding this mechanism helps clarify why HIV is serious but manageable. The virus specifically targets CD4+ T cells, which coordinate the immune response. Over time, if untreated, the loss of these cells leaves the body vulnerable to opportunistic infections and certain cancers. However, modern antiretroviral therapy can stop the virus from multiplying, preserving immune function and preventing transmission. The goal of treatment is to achieve an undetectable viral load, which also means the virus cannot be passed to sexual partners.
