Which virus causes HIV?

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

Answer: (A)

The virus responsible for HIV is the Human Immunodeficiency Virus. This virus attacks the immune system, specifically targeting CD4 cells, which are crucial for the body's ability to fight off infections. As HIV progresses, it can lead to Acquired Immunodeficiency Syndrome (AIDS), a condition characterized by a severely weakened immune system. Understanding HIV is essential for healthcare professionals, including dental hygienists, who may encounter patients living with the virus. The other options refer to different viruses that cause distinct health issues. The Hepatitis Virus is associated with liver infections, the Herpes Simplex Virus is known for causing oral and genital herpes, and the Human Papillomavirus is primarily linked to certain types of cancers. Each of these viruses has unique characteristics and modes of transmission, distinguishing them from HIV.
