Quick Answer

AIDS is the advanced stage of HIV infection, when the immune system is severely damaged and the body struggles to fight off certain infections or cancers. HIV is the virus that causes AIDS; with modern treatment, many people with HIV never develop AIDS.

  • HIV is a retrovirus that attacks CD4 cells, the immune system's helpers.
  • AIDS is diagnosed when CD4 count drops below 200 or an opportunistic infection appears.
  • Undetectable viral load means HIV is not transmitted sexually (U=U).
  • Antiretroviral therapy (ART) can keep HIV suppressed and prevent progression to AIDS.
  • AIDS is not a separate virus; it is the late stage of HIV.
  • With early treatment, life expectancy can approach normal.

Context Most Pages Skip

The letters AIDS stand for Acquired Immunodeficiency Syndrome, a term that describes the most severe phase of an HIV infection. Understanding the difference between HIV and AIDS matters because the two are often confused, yet they are not the same thing. HIV is the virus that enters the body and, without treatment, gradually weakens the immune system. AIDS is the clinical condition that results after years of untreated HIV, when the immune system has lost too many CD4 cells to defend against everyday germs. Modern antiretroviral therapy changes this trajectory: it can stop the virus from multiplying, keep the immune system healthy, and prevent AIDS from ever developing.
