ENNIS (CBSDFW.COM) – Students who had tested positive for the non-contagious form of tuberculosis in the Ennis Independent School District are able to return to classes on Monday morning. The health scare first surfaced in August. School officials said that a teacher was the initial carrier of the illness.

According to a press release issued by the district, students who are currently enrolled in classes at Ennis High School – including those who were previously excluded from being on campus due to an active or a suspected tuberculosis diagnosis – have been cleared to return.

While students are returning to campus on Monday, the teacher who is believed to be the initial carrier of the disease will remain away from campus.

School officials said that the most serious cases of tuberculosis have been identified. The district and state health officials analyzed 1,648 skin tests which were taken by both staff members and students in the Ennis ISD. Of those skin tests, 225 came back positive for a form of tuberculosis. But the disease, they said, is no longer spreading.

“This is tremendous news,” said Ennis ISD Superintendent Dr. Barbara Qualls in a written statement for the press, “as we are so pleased that these students are able to return from their treatments and resume their instruction at Ennis High School.”

School officials did not elaborate on how many people came down with the more serious, contagious form of the disease. State health officials plan to stay on campus to operate a latent tuberculosis infection clinic.
