Acquired immunodeficiency syndrome (AIDS) is one of the most devastating diseases of the modern era. AIDS is the most advanced stage of the human immunodeficiency virus (HIV), which interferes with an infected person’s immune system. The immune system is responsible for fighting off diseases, and over time, HIV infection weakens this system, leading to the development of AIDS. Individuals with AIDS are at a high risk of contracting life-threatening infections and contagious diseases, as well as certain forms of cancer. (Opposing Viewpoints)
