The disease AIDS, which stands for Acquired Immunodeficiency Syndrome, is caused by a virus known as HIV (Human Immunodeficiency Virus). This virus works by attacking the immune system, specifically targeting CD4 cells, which are crucial for the body's defense against infections. As the HIV virus depletes these cells, the body becomes increasingly vulnerable to various infections and diseases, ultimately leading to the progression of AIDS.

Understanding that AIDS is caused by a virus is fundamental in grasping concepts related to its transmission, prevention, and treatment. This knowledge also aids in recognizing the significance of antiretroviral therapy, which can manage the virus and prolong the lives of those affected, demonstrating the importance of correctly identifying the pathogen responsible for this syndrome.
