No more "active" cases of tuberculosis have been detected at the Air Force Academy.
A cadet came down with the disease in August. The school has been testing more than 42-hundred cadets ever since.
Officials say more than 230 cadets tested positive for exposure to the respiratory disease during the past two weeks. The cadets will be retested before they go home for winter break.
Health experts say people who test positive for exposure are not contagious, and may never develop the disease themselves.
Tuberculosis is the most common infection in the world, with more than five percent of the population testing positive.
Health officials earlier said Colorado could end up having more cases of tuberculosis this year than in the past two decades.
