A nurse helps move a patient dying of HIV-AIDS in Port Moresby

The USA Centers for Diseases Control published for the first time in 1982, what AIDS is. Their definition was "It is a special deficiency of cell-mediated immunity in persons with no known (inherited; a ) cause for diminished resistance.

It was only in 1984, that a reduction in the helper cell/suppressor cell ratio of less value of 1 was indicated as the measure of immunodeficiency.

Such changes in the helper cell/suppressor cell ratio are by no means diagnostic for a new disease, but they are known in several other sicknesses such as malaria caused by Plasmodium Falciparum, measles, glandular fever, Cytomegalo, Virus infection, Herpes simplex infection, atopic eczema, and mycotoxin.

Originally the Centers for Diseases Control defined AIDS to be the emerging of 25 unusual diseases or changes, although five of these diseases do not at all occur increased in AIDS and even occur without immunodeficiency.

Nocardiosis and Strongyloidosis for example, are tropical diseases, which in the USA have not played a part until now. In 1985, three other diseases were included in the definition. Two can also arise in persons without immunodeficiency. 

A new version of the Centers for Diseases Control definition was published in 1987. Main changes are Aspergillosis was deleted and an extrapulmonary disease caused by Mycobacterium tuberculosis was added.

A new, fourth version was published in 1992. Here evidence of less than 200 helper cells/ml in persons with HIV-antibodies is labelled AIDS no matter how healthy the persons are.
