HIV stands for which virus?

• A. Human Immunodeficiency Virus
• B. Human Influenza Virus
• C. Herpes Simplex Virus
• D. Hepatitis B Virus

Answer: (A)

Understanding what HIV stands for helps you see why it’s emphasized in infection control: HIV stands for Human Immunodeficiency Virus. It’s a virus that specifically attacks the immune system, weakening the body's defenses by targeting CD4 T cells. Because of this immune suppression, exposure to blood or certain body fluids requires strict precautions and proper post-exposure procedures to prevent transmission. The name itself describes its effect (immunity becomes compromised) and its nature as a virus. The other options refer to different pathogens—influenza is the flu virus, herpes simplex causes herpes infections, and hepatitis B virus causes hepatitis—so they are not the acronym HIV.
