We determined the prevalence of other sexually transmitted diseases (STDs) in 56 women infected with the human immunodeficiency virus (HIV) and compared the usefulness of this prevalence to that of standard risk assessment alone in identifying HIV-infected women. Of the 56 women studied, 54 were infected with HIV. These women received instruction as to the modes of transmission and were then placed in standard risk groups based on their own assessments. A history of previous or current STD was obtained and followed by appropriate testing. We found that combining standard risk assessment with a current or previous STD enabled us to identify a greater percentage of women who are infected with HIV.
