[HIV-infection and AIDS in the Netherlands: Prevalence and Incidence, 1987-2001]

Objective: To describe the results of HIV-surveillance activities in the Netherlands between 1987 and 2001.

Design: Descriptive.

Method: Data were obtained from HIV-surveillance at STI-clinics, laboratory-surveillance in the region Arnhem, surveillance among injecting drug users, the AIDS-notification, STI-registration and the Amsterdam cohort studies on HIV/AIDS.

Results: In the Netherlands, the highest HIV-prevalences were found among injecting drug users (1-26%) and homo- and bisexual men (0-17%). In these high-risk populations, an increase in HIV-prevalence and--incidence, respectively, was found among injecting drug users in Heerlen and homosexual men (> 35 years of age) in Amsterdam. The HIV-prevalence was lower among heterosexuals in the Netherlands (0-2%). However, in certain local populations an increase was seen. In both Amsterdam and Rotterdam, the HIV-prevalence was higher in individuals tested anonymously than in those tested by name.

Conclusion: Local increases in HIV-infections have been observed recently, in both high- and medium-risk populations.
