What does HIV stand for?

HIV stands for Human Immunodeficiency Virus. This term precisely describes the virus responsible for attacking the immune system, specifically targeting CD4 cells, which are critical for the body's ability to fight infections. Understanding the terminology helps clarify the nature of the virus and its impact on health. The use of "Immunodeficiency" in the name indicates that the virus leads to a decreased immune response, making individuals more susceptible to opportunistic infections and certain cancers.

The other options do not accurately capture the nature of the virus. "Human Immune Virus" and "Human Infection Virus" misrepresent the focus on how the virus affects the immune system, while "Healthy Immunodeficiency Virus" incorrectly suggests a positive state, which is contradictory to the conditions caused by HIV.
