What does AIDS stand for?

AIDS stands for "Acquired Immunodeficiency Syndrome." This term describes a condition characterized by a progressive failure of the immune system, caused by the HIV virus, which weakens the body's ability to fight infections and certain cancers. The acronym highlights two key aspects: "Acquired," indicating that it is not inherited but rather contracted; and "Immunodeficiency," signifying the significant impairment of the immune system's function.

The use of "Syndrome" indicates a group of symptoms and medical problems that occur together and are associated with this condition. Understanding the correct terminology is crucial for both medical professionals and the public, as misconceptions can lead to stigma or confusion regarding transmission and treatment of the disease.

In contrast, the other choices either include incorrect terms or inaccurately describe the condition, leading to misunderstandings about what AIDS actually represents in the context of public health and medical practice.
