In 2019, an Army laboratory at Fort Detrick that studies deadly infectious material like Ebola and smallpox was shut down for a period of time after a CDC inspection, with many projects being temporarily halted. ABC7 has received documents from the CDC outlining violations they discovered during a series of inspections that year, some of which were labeled serious." Earlier that year, the US Army Medical Research Institute had announced an experiment at the Fort Detrick laboratory that would involve infecting rhesus macaque monkeys with active Ebola virus to test a cure they were developing. Several of the laboratory violations the CDC noted in 2019 concerned "non-human primates" infected with a "select agent", the identity of which is unknown " it was redacted in all received documents, because disclosing the identity and location of the agent would endanger public health or safety, the agency says. In addition to Ebola, the lab works with other deadly agents like anthrax and smallpox. Select agents are defined by the CDC as "biological agents and toxins that have been determined to have the potential to pose a severe threat to public health and safety, to animal and plant health, or to animal or plant products." The CDC notes that the United States Army Medical Research Institute of Infectious Diseases had "systematically failed to ensure implementation of biosafety and containment procedures commensurate with the risks associated with working with select agents and toxins."
