 AB    OBJECTIVE: To compare sentinel survey prevalence rates of HIV antibody
       and p24 antigen in direct and indirect female sex workers, and male STD
       clinic users in 5 northern Thai provinces, and to measure HIV antibody
       negative, p24 positive prevalence METHODS: The Thai national sentinel
       surveillance for HIV has sampled high risk populations for HIV antibody
       twice-yearly since 1989. In 1991-1992 we added testing for p24 Ag to 3
       sentinel surveys in 5 northern provinces. HIV Ab was assayed with
       commercial ELISA, p24 with sandwich ELISA and confirmed with a
       neutralization assay. RESULTS: No HIV antibody negative p24 positive
       indirect CSWs were identified in 3 surveys of 100 women each. Direct sex
       workers and male STD patients showed: TABULAR DATA, SEE ABSTRACT VOLUME.
       CONCLUSIONS: The prevalence of both HIV Ab and HIV p24 Antigenemia has
       been increasing in 2 groups of high risk northern Thai adults. Of 34 HIV
       p24 positive subjects, 22 (65%) were HIV Ab negative by ELISA.
