The Women’s Interagency HIV Study (WIHS) was established in August of 1993 to investigate the impact of HIV infection on women in the U.S. The core portion of the study includes a detailed and structured interview, physical and gynecologic examinations, and laboratory testing. The WIHS participants are also asked to enroll in various sub-studies, such as cardiovascular, metabolic, physical functioning, and neurocognition. New proposals for WIHS sub-studies are submitted for approval by various scientific investigators from around the world.

Please visit the WIHS Dossier for key summary statistics and a summary of published WIHS papers.

Proposals must focus on innovative investigations and must have scientific merit (Please visit our Investigator Information page if you are interested in submitting a scientific proposal to the WIHS). The WIHS welcomes collaborations with other HIV-specific cohorts. If you are interested in
learning more about potential and ongoing collaborations with the WIHS, please visit our Collaborations page.

The WIHS is funded by the following government agencies: the National Cancer Institute (NCI), the National Center for Research Resources (NCRR), the National Institute of Allergy and Infectious Diseases (NIAID), the National Institute of Child Health and Human Development (NICHD), and the National Institute on Drug Abuse (NIDA).

The WIHS continues to produce highly successful investigations on HIV infection in women. In addition, the WIHS continues to define the status of women with HIV in the early 21st century, while bridging the gap between theoretic benefits and sustainable gains of antiretroviral therapy.
