TOMS RIVER - A routine skin test in January found 34 employees at HeathSouth Rehabilitation Hospital of Toms River were exposed to tuberculosis.

None of those that tested positive have shown any symptoms such as heavy cough, excessive sweating or fever. According to the hospital's CEO, Patty Ostaszewski, the lung disease is dormant in their bodies.

The Ocean County Health Department says it has no reason to close the facility since there are no known active cases there, but it has asked all employees to get tested. The hospital's medical director, Dr. Joseph Stillo, suspects it came from an elderly male patient at the end of last year.

The Ocean County Health Department says its investigation into the source remains ongoing.
