In the early days, the CDC did not have an official name for the disease, often referring to it by way of diseases associated with it, such as lymphadenopathy, the disease after which the discoverers of HIV originally named the virus. They also used "Kaposi's sarcoma and opportunistic infections", the name by which a task force had been set up in 1981. At one point the CDC referred to it as the "4H disease", as the syndrome seemed to affect heroin users, homosexuals, hemophiliacs, and Haitians. The term "GRID", which stood for gay-related immune deficiency, had also been coined. However, after determining that AIDS was not isolated to the gay community, it was realized that the term "GRID" was misleading, and the term "AIDS" was introduced at a meeting in July 1982. By September 1982 the CDC started referring to the disease as AIDS.
