Being HIV positive does not mean that you have AIDS, but it does mean that you may develop AIDS. Many people are alive and live well above fifteen years or more after testing HIV positive.IV-positive means infected with the virus that causes AIDS or Auto-Immune Deficiency Syndrome. The virus attacks the immune system and destroys T-cells. It makes a person mor â¦ e likely to get a number of diseases.
When the test incorrectly indicates that HIV is absent in an infected person, this is called a false negative. Positive or negative means that the doctor looked for substances the body produces to fight the HIV virus, but not the virus itself.
