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. 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.

If you are interested in submitting a scientific proposal for consideration by the WIHS, please visit the Investigator Information page for more information. Additionally, 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 the Collaborations page.

The WIHS dedicates this website to all WIHS participants for dedicating their time and effort to the study. Their contributions have been invaluable to the WIHS and women's HIV research and their commitment inspires many.
