DENTON (CBSDFW.COM) – It doesn’t look like Denton’s problem with tuberculosis will be near as bad as it was in Ennis.

Chest X-rays performed on students and staff at Denton High School for possible cases of tuberculosis all show no sign of active TB. That means there are no new cases of TB and no indication of an outbreak at the school.

Tests of about 300 students got underway after a student with TB transferred to Denton High from Ennis.
