Acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV). The illness interferes with the immune system, making
people with AIDS much more likely to get infections, including opportunistic infections and tumors that do not usually affect
people with working immune systems.
