Myth: If Iâm diagnosed with HIV, my life is over. Fact: Having HIV does not automatically mean you have AIDS. Many years may pass before people with the virus feel ill or develop the disease. Many people now live long and active lives with HIV because of medical advancements.
People who have HIV and donât get treatment almost always die from the virus. But with medication, people with HIV can be healthy and live a long time. Whatâs the difference between HIV and AIDS? HIV is the virus that causes AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. HIV and AIDS are not the same thing. And people with HIV do not always have AIDS. HIV is the virus thatâs passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system (called CD4 cells or T cells) that helps protect you from infections. When you donât have enough of these CD4 cells, your body canât fight off infections the way it normally can.
