1985 World Health Organization AIDS surveillance case definition

The 1985 World Health Organization AIDS surveillance case definition was developed in October 1985, at a conference of public health officials including representatives of the Centers for Disease Control (CDC) and World Health Organization (WHO) in Bangui, Central African Republic. For this reason, it became to be known as the Bangui definition for AIDS. It was developed to provide surveiling case definition of AIDS for use in countries where testing for HIV antibodies was not available.

It stated the following:

Exclusion criteria

  1. Pronounced malnutrition
  2. Cancer

The diagnosis of AIDS is established when the score is 12 or more.

Revision

The 1985 WHO AIDS surveillance case definition was heavily criticised, for both medical and political reasons. The 1994 expanded World Health Organization AIDS case definition was introduced in 1994 to incorporate the statement that HIV testing should be done. However, if testing was unavailable, then the Bangui definition should be used.
