Human immunodeficiency virus infection and acquired immune deficiency syndrome(HIV/AIDS) is a diseasespectrum of the human immune system uh caused by infection with human immunodeficiency virus(HIV).Following initial infection, a person may experience a brief period of influenza-like illness. This is typically followed by a prolonged period without symptoms. As the infection progresses, it interferes more and more with the immune system, making the person much more susceptible to common infections like tuberculosis, as well as opportunistic infectionsand tumorsthat do not usually affect people who have working immune systems. The late symptoms of the infection are referred to asAIDS. This stage is often complicated by an infection of the lung known as pneumocystis pneumonia, severe weight loss, a type of cancer known as Kaposis sarcoma, or other AIDS-defining conditions.
