What does 'HIV' stand for?

The correct answer is that 'HIV' stands for Human Immunodeficiency Virus. This term describes a virus that attacks the body's immune system, particularly the CD4 cells (T cells), which are crucial for fighting infections. Over time, if not treated, HIV can lead to the disease known as AIDS (Acquired Immunodeficiency Syndrome), which severely compromises the immune system and increases susceptibility to opportunistic infections and certain cancers.

Understanding the term and its implications is crucial in various fields, including cosmetology, where practitioners must be aware of safety protocols concerning bloodborne pathogens. While some of the other options include terms that sound plausible or similar, they do not accurately represent the definition or context of HIV. By knowing what HIV stands for, individuals can better educate themselves about the virus and the importance of preventing its transmission.
