Mystery Illness Strikes: 19 Cadets Hospitalized from DC Area Youth Military Academy

A sudden wave of illness struck at a youth academy with military-style training near Washington, D.C., sending at least 19 cadets to local hospitals on Sunday. The mysterious sickness triggered a mass casualty response, according to officials.

Emergency personnel quickly arrived at the Capital Guardian Youth Challenge Academy in Laurel, Maryland, after cadets started showing symptoms following lunch, shared the DC National Guard, with reports from FOX 5 DC.

The Capital Guardian Youth Challenge Academy, run by the DC National Guard, offers a structured, military-style life intervention program for teenagers identified as at risk, as described by the academy itself.

One mother told FOX 5 that blood tests at a hospital showed her son had elevated carbon monoxide levels. He reportedly developed delayed symptoms hours after other cadets were taken for treatment, including dizziness, headaches and nausea.

The mother added that the youth academy decided to temporarily close following the incident.

However, Anne Arundel County Fire Department officials said they conducted a carbon monoxide investigation and did not detect elevated levels of the gas, according to the local station.
