A resarch associate at the University of Colorado-Boulder who taught this summer in the School of Education has tested positive for tuberculosis, officials said today.

The associate is a Denver resident who has submitted to a voluntary home quarantine, according to Denver Health Medical Center officials who are working with Boulder Public Health and CU officials.

The person's name, sex, age and related information were not released.

"We do not feel this individual represents a health threat to our larger student body and campus community," said Gary Chadwick, director of Wardenburg Health Center on the CU-Boulder campus.

Denver Health officials estimate that six people had sufficient contact with the patient to require testing. However, as a precautionary measure, a number of family members, faculty, staff and associates of the faculty member also were tested.

Laboratory results can take two to three weeks to determine the precise strain of tuberculosis.

It is not yet known how the faculty member was exposed to tuberculosis.
