What virus is known for causing AIDS?

The virus known for causing AIDS is HIV, which stands for Human Immunodeficiency Virus. This virus attacks the body’s immune system, specifically targeting CD4 cells (T cells), which are crucial for the immune response. As the infection progresses, it can lead to the condition known as Acquired Immunodeficiency Syndrome (AIDS), characterized by a severely weakened immune system that cannot effectively fight off infections and diseases.

HIV is primarily transmitted through certain body fluids from a person who has HIV. It can be spread through sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding. Understanding the role of HIV in the progression to AIDS is critical for public health awareness and prevention strategies.

The other viruses listed, such as HCV (Hepatitis C Virus), HPV (Human Papillomavirus), and HBV (Hepatitis B Virus), are associated with different diseases and health complications but do not cause AIDS. Therefore, recognizing HIV as the causative agent of AIDS is essential for anyone studying in the medical or health fields.
