Fort Detrick (/ˈdiːtrɪk/) is located in Frederick, Maryland. Fort Detrick was the center of the U.S. biological weapons program from 1943 to 1969. Since the discontinuation of that program, it hosted most elements of the United States biological defense program.
As of the early 2010s, Fort Detrick's 1,200-acre (490 ha) campus supports a multi-governmental community that conducts biomedical research and development, medical materiel management, global medical communications and the study of foreign plant pathogens. The lab is known to research pathogens such as Ebola and smallpox.
