 AB    OBJECTIVE: In order to elicit the seroprevalence of HIV in the people at
       the Tokyo district, we have been engaged in HIV antibody testing from
       1987. METHODS: HIV antibody testing has been done for the persons who
       have visited health centers of Tokyo metropolitan district, using ELISA
       as the screening test, western blot and indirect immunofluorescent assay
       as the confirmation test. HIV-1 seropositive samples were tested for
       subtyping with V3 peptide ELISA. RESULTS: 193 HIV seropositive samples
       have been detected among 66731 samples that have been assayed since Feb.
       1987 to Dec 1993. 113 seropositive samples and 72 ones were detected in
       1992 and 1993 respectively. 152 samples out of seropositive ones were
       assayed to differentiate HIV-1 from HIV-2, and all were positive for
       HIV-1. In typing of V3 peptide ELISA, Euro-American type and Thai type
       has been predominant. DISCUSSION AND CONCLUSIONS: It is suggested that
       the infection rate of HIV-1 has been increased in a recent few years.
       HIV-2 infection has not yet prevailed among the people in Tokyo, we are
       going to the surveillance of HIV-2 as well as HIV-1.
