Acquired immunodeficiency syndrome (AIDS) is the most severe stage of HIV infection. HIV is a virus that attacks the immune system, the body's natural defense system. White blood cells are an important part of the immune system. HIV infects and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection. Both the virus and the infection it causes are called HIV.
Medicines can reduce the amount of virus in the body and improve your health. If HIV is not treated, it will usually get worse over time and cause AIDS. People who have AIDS have a low number of CD4+ cells. They get infections or cancers that rarely occur in healthy people. These can be deadly.

If your partner has AIDS, you can help provide emotional, physical, and medical care that will improve their quality of life.
