For over 100 years, NIH has supported biomedical research to enhance health, lengthen life, and reduce the burdens of illness and disability. The Fact Sheets on this site tell the stories of research discovery, current treatment status, and future expectations for the prevention and treatment of diseases and conditions affecting the nation's health. Several of the Sheets also describe NIH policies and organizations in place to enhance public health safety and the public understanding of health science.

Search through the Fact Sheets and follow the interactive links for additional information on NIH-supported clinical studies, initiatives, and research endeavors currently underway. Each Sheet also contains links to the homepages of relevant NIH Institutes, Centers, or Offices.
