WILSON COUNTY, TN (WSMV) - There's growing concern over the possible spread of tuberculosis. Hundreds of students at risk.
That's because someone at Wilson Central High School tested positive for it.
On Wednesday, worried parents wanted to know how long that person was walking around with tuberculosis and where it came from.
News4 spoke with Myrna Davis learned one of her daughters may have been exposed to the disease.
"The first thought is that's what's wrong with her? So, we went today and got tested. We're not waiting," Davis said.
Principal Travis Mayfield sent an email to parents Tuesday letting them know 450 students and staff members will need to be tested.
That's about a fourth of the school population.
"I hope that all those they screen, negative, every one of them. That's what my hope is," Mayfield.
Mayfield said he learned about the case on Friday.
State health department officials told parents not to panic. They said it would take a lot more than walking through the school hallway to get the air borne disease.
They'll be testing for it next week, which doesn't sit well with some parents.
"We're going to go to school for another week and then we're going to test this 450 and if one of them have it, then odds are these other 450 do too. So, now you're talking about half the school. Where does it end?," Davis said.
The person who has tuberculosis hasn't been at school since being diagnosed.
Mayfield said the school has changed air filters in all the classrooms, and all school buses that service Wilson Central High School have been sanitized.
