The discoverer of HIV even in the first name with the name of the AIDS virus. The CDC started using the word AIDS in September 1982, and defines the disease. In 1993, the CDC expanded their definition of AIDS to include all people the number of CD4 + T cells below 200 per mL of blood or 14% of all limfositnya as people with HIV positive.
