Which virus is responsible for causing AIDS?

Human Immunodeficiency Virus (HIV) is the virus responsible for causing Acquired Immunodeficiency Syndrome (AIDS). HIV attacks the body’s immune system, specifically targeting CD4 cells, which are crucial for immune defense against infections and diseases. If left untreated, HIV can progress to AIDS, where the immune system becomes severely compromised, making the individual more susceptible to opportunistic infections and certain cancers.

Understanding the role of HIV in the development of AIDS is fundamental to recognizing how the virus is transmitted, the importance of early diagnosis, and the efficacy of antiretroviral therapies in managing the infection. This knowledge is critical not only for healthcare professionals but also for public health education, as it highlights the need for prevention measures and treatment options available to those infected with HIV.
