[Telephone duty "AIDS Information" at the Vaudois University Hospital Center: who calls and why?].

From January 1989 to December 1990, 7653 phone calls were answered by the AIDS Hot Line of the Centre Hospitalier Universitaire Vaudois. Most of the calls were from the general public (82%), 12% from health care workers and 6% from HIV-infected subjects. The main reasons for calling were information regarding the HIV test (public), scientific inquiries (health care works) and requests for medical or social support (HIV-positive persons).

[364 anonymous screening tests for AIDS at the Vaudois University Hospital Center: who? why?].

From 1 July to 31 December 1988 risk factors for HIV infection were systematically recorded for all individuals tested anonymously at our institution and compared with similar data observed when anonymous testing was introduced (1985-1986). The absolute number of homosexuals and intravenous drug abusers remained stable but their ratio decreased because most tests are now performed in persons with multiple heterosexual partners. More than half of heterosexuals said they used condoms.
