[Epidemiological surveillance of HIV-seropositive subjects identified in Provence-Alpes-Cote d'Azur in 1996-1997].

OBJECTIVE

The aim of this study was to assess trends in new HIV-positivities identified in the Provence-Alpes-Cote d'Azur area in southern France in 1996 and 1997 and to identify any weaknesses in the screening policy.

METHODS

Data were collected from the EVALVIH epidemiological surveillance system initiated in 1995. The data were obtained from both anonymous reports of medical biology laboratories and of prescribing physicians in the area.

RESULTS

From January 1996 to December 1997, 825 persons (67% men, 33% women) were found to be HIV-positive. Although the percentage of intravenous drug users (18%) and homo-bisexual individuals (23%) remained high, the proportion of heterosexuals was higher (45%). The number of identified cases of HIV seropositivity fell from 271 in the first semester 1996 to 137 in the second semester 1997, i.e. a 49% decline (p < 0.001). There was no significant difference in this trend for age, gender, transmission mode, or geographical origin of the subjects.

CONCLUSION

These results confirm the positive impact of the HIV prevention program in the Provence-Alpes-Cote d'Azur region and the insufficiencies of the screening policy requiring urgent reconsideration.
