What does the acronym "AIDS" stand for?

The acronym "AIDS" stands for Acquired Immunodeficiency Syndrome. This term reflects the condition that arises due to the infection with the Human Immunodeficiency Virus (HIV), which progressively weakens the immune system. The word "acquired" indicates that the syndrome is not inherited but is developed after exposure to the virus. "Immunodeficiency" refers to the reduced ability of the immune system to fight off infections and diseases. "Syndrome" signifies that it encompasses a group of symptoms and signs associated with the progression of HIV infection.

The other options include terms that do not accurately reflect the medical terminology used to describe the disease. For instance, "Autoimmune Immunodeficiency Syndrome" implies an autoimmune origin, which is not the case for AIDS, since it is caused by a viral infection. Similarly, "Affective Immune Deficiency Syndrome" and "Acquired Immune Disease Syndrome" misstate the nature of the syndrome and do not correspond with established medical terminology for this condition. Understanding the correct terminology is crucial for healthcare professionals to communicate effectively about HIV/AIDS and its implications.
