AIR FORCE ACADEMY, Colo. -- Thirty more cases of the H1N1 virus, also known as swine flu, have been reported by the Air Force Academy, bringing the total number of confirmed cases on the campus to 97.

Of those, 93 cadets remained isolated with influenza-like symptoms.

Academy spokesman said the outbreak has probably reached its peak.

"We're having less in isolation now," John Van Winkle said. "We're on the downward trend."

The academy outbreak is the largest so far in Colorado, which reported 146 confirmed cases through last week.

Those showing symptoms were placed in a separate dormitory on the base near Colorado Springs late last week.

The "doolies," or members of the incoming freshman class, are among about 1,300 recent arrivals for their first weeks of military training.
