Quick Answer

AIDS starts when HIV, a retrovirus, has severely damaged the immune system, allowing opportunistic infections or certain cancers to develop. It is the advanced stage of HIV infection, not a separate germ. With modern treatment, HIV can be controlled so that it never progresses to AIDS.

  • HIV is a retrovirus that attacks CD4 immune cells.
  • AIDS is diagnosed when CD4 count drops below 200 or an opportunistic infection appears.
  • HIV spreads through blood, semen, vaginal fluids, and breast milk.
  • Not everyone with HIV develops AIDS, especially with treatment.
  • Undetectable viral load means HIV cannot be transmitted sexually.
  • HIV is not present in every human body; it is an infection, not a normal state.

Most people know that HIV can lead to AIDS, but the path between them is often misunderstood. HIV stands for human immunodeficiency virus, and it works by entering and destroying CD4 cells, which are the immune system's coordinators. Over time, if the virus is not controlled, the immune system weakens to a point where the body can no longer fight off infections that a healthy person would easily handle. That vulnerable state is what doctors call AIDS, or acquired immunodeficiency syndrome. The key point is that AIDS is not a new infection; it is the late stage of an untreated or poorly treated HIV infection. Understanding this progression helps clarify why early testing and treatment are so important.

When does aids start?

Timelines vary by infection. Bacterial STIs like chlamydia and gonorrhea show up on NAAT tests within 1–2 weeks, syphilis needs 3–6 weeks, HIV appears on modern lab tests within 18–45 days, and reliable herpes blood tests wait 12–16 weeks.
