What does HIV stand for?

HIV stands for Human Immunodeficiency Virus. This term accurately reflects the nature of the virus, which specifically attacks the immune system, impairing the body's ability to fight off infections and diseases. The term "immunodeficiency" is crucial because it describes the weakened state of the immune system that occurs in an individual infected with HIV. Over time, if untreated, this virus can lead to Acquired Immunodeficiency Syndrome (AIDS), which represents a more advanced stage of infection.

The incorrect options do not accurately describe the virus or its function in the body. For example, "Human Immunity Virus" and "Human Immune Virus" are misleading because they suggest the virus supports or maintains the immune system rather than weakening it. "Human Insulin Virus" is not related to HIV at all and incorrectly references insulin, which is a hormone central to glucose metabolism rather than the immune response.
