Which virus is known to cause AIDS?

The virus that is known to cause AIDS is HIV, which stands for Human Immunodeficiency Virus. HIV attacks the body's immune system, specifically the CD4 cells (T cells), which play a critical role in helping the body fight off infections. Over time, as HIV destroys these cells, the immune system becomes weaker, leading to the development of AIDS (Acquired Immunodeficiency Syndrome), the most advanced stage of HIV infection.

HIV is primarily transmitted through contact with infected bodily fluids, and without treatment, it can progress to AIDS, characterized by the occurrence of certain opportunistic infections and diseases due to a severely weakened immune system. Understanding the nature of HIV is crucial for prevention, treatment, and education regarding the transmission and progression of the virus.
