School officials say 25 of the 175 students
and staff members tested for tuberculosis at Meadowcreek High
School had positive readings and now must have a chest X-ray.

Sloan Roach, spokeswoman for Gwinnett County Public Schools,
said those with positive readings showed no signs or symptoms of
having TB. She said the results of their skins tests just indicated
they have been exposed to TB at some time in their lives.

The school system said those who were tested for the airborne
disease were identified as people who were in closest and
continuous contact with an 11th-grader who had a suspected case of
TB.
