The Ambassadors said, HIV is the virus that causes AIDS. AIDS is the most advanced stage of the HIV disease.

HIV is a virus that attacks the body’s helper T cells, which are an important part of your immune system. Without T cells, your immune system is vulnerable to attack. When a person is infected with HIV, if they do not take their medications to keep the virus from attacking the T cells, HIV will keep on attacking T cells, and if the T cell count gets low enough, HIV can progress to AIDS. When a person has AIDS, they are much more vulnerable to everyday illnesses because their immune system can no longer keep them healthy.
