At least 19 cadets at a military‑style youth academy in the Washington, D.C., area were taken to area hospitals on Sunday after reporting symptoms of an unknown illness, prompting a mass casualty response.
Emergency crews responded to the Capital Guardian Youth Challenge Academy in Laurel, Maryland, after cadets began experiencing symptoms following lunch. The academy is operated by the DC National Guard and serves as a life‑intervention program for at‑risk teens.
One parent said blood tests at a hospital showed elevated carbon monoxide levels in her son. He developed delayed symptoms hours after other cadets were treated, including dizziness, headaches, and nausea.
The parent added that the academy decided to temporarily close after the incident.
Anne Arundel County Fire Department officials said they conducted a carbon monoxide investigation and did not detect elevated levels of the gas.
Officials said they have not yet determined the cause of the illness but suspect it may be related to food.
DC National Guard officials said the health and safety of cadets and staff remain their highest priority and that they are working with emergency medical personnel and public health authorities as the investigation continues.
While 19 cadets were sent to area hospitals, one adult was evaluated at the scene and declined further medical treatment.
