Acquired Immune Deficiency Syndrome (AIDS) is a serious condition caused by the human immunodeficiency virus (HIV), which attacks the immune system and weakens the body's ability to fight off infections and diseases. AIDS is considered the advanced stage of HIV infection, characterized by a significant decline in immune function and the development of infections or cancers. Symptoms of AIDS can include repeated fevers, unexplained weight loss, persistent diarrhea, and intense fatigue. Without treatment, AIDS can be life-threatening. However, with advancements in antiretroviral therapy (ART), many people with HIV can prevent the progression to AIDS and live long and healthy lives.
