[Seroprevalence of HIV infection among sexually transmitted disease clinic attenders. Study Group of the Seroprevalence of Anonymous HIV Unrelated to Patients Consulting a Sexually Transmitted Disease Clinic].
BACKGROUND
To estimate the seroprevalence of HIV infection among sexually transmitted disease (STD) clinic attenders.


METHODS
Unlinked anonymous serologic survey among patients from six STD clinics in 1998.


RESULTS
Among 1,303 patients 3.7% were found to be infected by HIV. Seroprevalences were 48.3% in injecting drug users, 16.7% in homosexual men, 1.3% in prostitutes, 0.9% in heterosexuals from sub-Saharan Africa or Caribbean, and 3.1% in other heterosexuals.


CONCLUSIONS
In STD clinics attenders heterosexuals from sub-Saharan Africa or Caribbean and prostitutes showed the lowest seroprevalences of HIV infection.
