“When HIV is left untreated, it can wreak havoc on a person’s immune system. As this happens, the body is less able to fight off infections. AIDS stands for “Acquired Immune Deficiency Syndrome,” which means the immune system has been made less effective by HIV. When this happens, a person is considered to have an acquired immune deficiency or AIDS.
It’s important to note that you cannot have AIDS without being infected with HIV. But people can, and do, live long lives (on treatment) with HIV and never develop AIDS.
Once you have HIV, the virus stays in your body for life. There’s no cure for HIV, but medicines can help you stay healthy.”
