HIV is a virus. AIDS is a condition caused by HIV.
You can have HIV without developing AIDS, and many people live for many years with HIV without ever developing AIDS. But if you have AIDS, you have to have HIV.
The National Institutes of Health (NIH) have more detailed information about the medical diagnosis of AIDS, which consists of having HIV plus having a very low count of CD4 cells and/or an opportunistic infection. CD4 cells are part of the immune system, and are attacked/destroyed by HIV.
The best way to fight HIV is to know your status. A simple test can determine if you are infected with the virus.
Our diverse programs help thousands of people every year. From testing to prevention to care, our services assist communities where need is greatest.
