Human immunodeficiency virus (HIV) sero-prevalence in sexually transmitted disease clinic populations.

Two HIV sero-prevalence surveys conducted during 1989 in public sexually transmitted disease clinics in the Kansas City SMSA tested 1,561 males and 1.043 females. There were 23 sero-positive males; no sero-positive females. The rate for males using the Missouri clinic was nearly triple that of males using the Kansas clinic. Among males the sero-prevalence rate for white males was 8.4 times that for black males. Of the 14 HIV sero-positive males for whom risk factor information was available, 12 were gay or bisexual and two were heterosexual intravenous drug users.
