Due to the COVID-19 pandemic, NIH is limiting visitors at all facilities. All non-essential visits should be re-scheduled.
Face coverings are required at all NIH facilities.
The NIH headquarters, known as the “NIH campus” to the local community, are located in Bethesda, Maryland. Administrative and program operations facilities are also located in off-campus buildings in the surrounding area. NIH scientists conduct their research in laboratories located on the main campus, and in several field units across the country and abroad.
