HIV/AIDS
The human immunodeficiency virus (HIV) targets the body’s immune system and weakens it against many infections—including some types of cancer—a healthy immune system can typically fight off. As the virus destroys and impairs the function of immune cells, those infected gradually become immunodeficient. The most advanced stage of HIV infection is known as acquired immunodeficiency syndrome (AIDS), which, if not treated, can take years to develop, depending on the individual. There is no cure for HIV infection. However, through increasing access to effective HIV prevention, diagnosis, treatment, and care, including for opportunistic infections, HIV infection has become a manageable chronic health condition, enabling those living with HIV to lead long and healthy lives.
