What does the abbreviation AIDS stand for?

The abbreviation AIDS stands for Acquired Immune Deficiency Syndrome. This term refers to a condition in which the immune system becomes severely weakened, rendering the body unable to effectively fight off infections and diseases. The "acquired" aspect indicates that this syndrome is not hereditary but is instead developed after birth, typically as a result of infection by the human immunodeficiency virus (HIV).

The term "immune deficiency" reflects the impairment of the immune system, leading to a higher vulnerability to opportunistic infections and certain cancers. Lastly, "syndrome" is used because AIDS is not a singular disease but a collection of symptoms and conditions that occur together. Understanding this terminology is crucial for recognizing the severity and implications of the condition, which is why the correct answer is essential for providing clarity on the subject.
