US AIR FORCE ACADEMY, Colo. –  More than 200 Air Force Academy cadets, along with some active-duty personnel, have been stricken with stomach flu, the school said Tuesday.

A news release from the academy said no one had been hospitalized and the 240 cadets and other personnel were being treated with oral and intravenous fluids along with anti-nausea medication.

The Colorado Springs Gazette reported Tuesday that about 180 cadets had been placed in isolation in one of two cadet dormitories.

The first cases were reported last week.

Most of the ill were reportedly among an incoming class of 1,100 who arrived last month.

"The health and safety of our cadets and all those who live and work at the Air Force Academy is our top priority," said Air Force Academy Superintendent Lt. Gen. Mike Gould. "We understand this is a serious matter, and we're taking steps to inform Academy personnel and the community of the precautions necessary to ensure their safety."
