 AB    OBJECTIVE: To estimate the seroprevalence of human immunodeficiency
       virus type 1 (HIV-1) infection in primary care practices. METHODS:
       Fifty-four practices in the United States participated in an anonymous,
       unlinked HIV seroprevalence study between January 1990 and December
       1992. Residual blood samples drawn for routine clinical tests from
       patients 15 to 49 years of age were centrally tested for the HIV-1
       antibody for 1 month of each quarter. Information about patient
       demographics, clinician-recognized risk factors, the known HIV status of
       the patient, and whether the blood was drawn for HIV testing was
       recorded with each specimen. RESULTS: Of 21,998 specimens collected, 99
       (0.45%) were seropositive. Of these 99 seropositive persons, 31.3% (a
       seroprevalence of 0.15%) were not suspected by their clinicians of being
       infected with HIV. Seroprevalences in men (0.96%) exceeded those in
       women (0.22%), and rates in rural practices (0.18%) were lower than in
       urban practices (0.71%). Among patients with unsuspected HIV infection,
       however, the gender differences, especially in rural areas, were less
       pronounced. Risk factors for HIV infection were infrequently noted.
       There was an increase in the overall seroprevalence during the 1990 to
       1992 study period (0.36% to 0.53%); however, this trend was not
       statistically significant. CONCLUSIONS: Within a 3-year period,
       clinicians in at least two of five primary care practices can expect to
       encounter patients infected with HIV, regardless of practice location.
       Also, nearly one third of the patients with HIV infection will not be
       suspected of having this condition by their clinician.
