title: [Anonymous and free-of-charge centers for screening for HIV infection. Results of 30 months of activity in Public Assistance in Paris hospitals].
abstract: The results of 30 months of activity of anonymous and free-of-charge HIV detection centres in Paris hospitals are presented. During this period (April 1988 to December 1990), 15805 subjects were seen. This population accounts for about 11 percent of all French anonymous and free detection centres  in 1990, and for 26 percent of the number of subjects consulting in detection centres of the same type. Risk factors could be listed in 8132 consulting subjects: 73 percent were heterosexuals and not drug-addicts; 19.5 percent were homo- or bisexuals; 6 percent were drug-addicts; 0.6 percent were both homosexuals and drug-addicts; 29 percent of the 7806 persons questioned about their use of condoms stated that they used them often or always. A total of 15271 blood samples were taken. The percentage of seropositivity was 4.73 percent with a significant fall from 5.87 percent in 1988 to 4.38 percent in 1990; 23.4 percent of homosexual drug-addicts, 17.6 percent of heterosexual drug-addicts, 9.3 percent of homo- or bisexuals and 1.3 percent of heterosexuals were seropositive. In the seropositive population, 46.4 percent were homo- or bisexuals, 29.8 percent were drug-addicts, 19.7 percent were heterosexuals and 3.7 percent were homosexual drug-addicts. Three subjects had been contaminated by blood transfusion. The percentage of seropositive subjects in our study was superior to the mean found in other anonymous and free detection centres (4.73 percent versus 3 percent in 1990), this probably reflecting the high prevalence of the infection in the Paris region. The seropositive subjects usually belonged to the categories primarily affected by the HIV. The percentage of seropositivity in our drug-addicts (17.6 percent) was much lower than that usually reported in French drug-addicts (30 to 40 percent).
