OBJECTIVE: To determine the modalities of application and impact of the revised CDC/WHO AIDS case definition on surveillance in Europe.

METHODS: A survey was carried out among the 32 countries of the WHO European region investigating modalities of surveillance of AIDS and application of revised cases definition.

RESULTS: Of 20 countries having answered by end of January 1989, 15 have set up a surveillance system for HIV+ individuals. 20 countries have an AIDS surveillance system of which 13 are mandatory and 6 voluntary. Under reporting has been assessed by few countries 9/20 mostly by matching AIDS cases with death certificates. Revised case definition was applied in all 20 countries by 01/01/88. Six countries have actively carried out a retrospective investigation on cases previously reported with AIDS and 3 have also investigated HIV patients not previously diagnosed with AIDS. 636 AIDS patients fitting the revised case definition have been reported representing an increase of 4%. This is much lower than figures reported in literature.

CONCLUSION: Most of the 20 countries having answered by end of January 1989 had applied the case definition by first of January 1988. Impact of new cases is extremely low and will be assessed when complete set of answers are received.
