persons who correctly or incorrectly reported no history of risk behavior or no
partner[s] at risk for or infected with HIV) (Table 2). These two heterosexual groups
had a combined seropositivity rate of 2.0%, yet accounted for 28.1% of reported
positive tests for persons whose risk category was reported. For the "heterosexual
with reported risk" category, seropositivity rates by reported partner characteristic
were: partner infected with HIV, 11.7% (1455/12,440); partner with hemophilia, 5.1%
(34/667); IV-drug-using partner, 5.0% (1792/36,167); and bisexual partner, 4.1%
(2312/56,830).

*Totals vary from those in Table 2 because of variance in reporting by both persons and test
sites.
Of 828,847 tests for which some demographic information was given, race/
ethnicity was specified for 754,900 (91.1%). Of tested persons with known race/
ethnicity, seropositivity was highest in Hispanics (8.6%) (Table 3). When compared to
the overall U.S. population, both blacks and Hispanics were substantially overrepresented among HIV-antibody tests and positive tests.
Males accounted for 459,046 (55.4%) of the 828,847 tests and 30,758 (79.7%) of all
positive tests. Seropositivity in males and females was 6.7% and 2.1%, respectively.
Of 735,584 persons for whom age was known, most (73.1%) tests and most (78.9%)
positive tests were from persons aged 20-39 years. Seropositivity rates for persons
aged 20-29 and 30-39 years were 3.6% and 6.0%, respectively.
