What does the abbreviation HIV stand for?

The abbreviation HIV stands for Human Immunodeficiency Virus. This virus is a significant health concern as it attacks the body’s immune system, specifically targeting CD4 cells (T cells), which are crucial for immune response. Over time, if untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), where the immune system is severely compromised, leading to increased susceptibility to infections and diseases. Understanding this acronym is fundamental in the medical field, especially in discussions of virology, infectious diseases, and public health. The other options do not relate to a viral infection or the context of immunology, demonstrating the specificity of the correct choice regarding its medical significance.
