LANSING, Mich. -

State health officials are investigating a case of tuberculosis exposure at four health care facilities in Detroit.
 
The Michigan Department of Community Health said Thursday a worker unknowingly was ill with TB and worked last year at multiple hospitals. The MDCH says the worker was in contact with about 560 patients who received dental care between Aug. 1 and Dec. 17.

The worker has not been identified.

The affected Detroit health care facilities are: Detroit Medical Center, Henry Ford Hospital, St. John Hospital and Medical Center and University of Detroit Mercy School of Dentistry.

Patients and staff who may have been exposed have been notified and encouraged to get tested.

TB is a treatable bacterial disease that can be serious and is spread through the air from one person to another.

Detroit Department of Health and Wellness Director Vernice Davis Anthony told Local 4 the number of TB cases being tracked in the city is minimal.

"Right now, we have no more than about 12 cases of TB in the city of Detroit. So, it's not a disease that is really widespread," she said. "Just because you've been exposed doesn't mean you have the disease."
