(Memphis) Final exams start a week away at Wooddale High School, but the test results everyone's waiting on are from tuberculosis tests after someone at the school got infected.
Tuberculosis is a very contagious bacterial infection that can spread just by having a conversation with an infected person.
Parents of students Wooddale High say they found out about the infection at the school by watching it on the news.
Linda Rudd's granddaughter goes to Wooddale.
"I am like what the hell? We are over here everyday picking up kids. I heard nothing about it I asked my granddaughter if she got a letter, she said no ma'am."
The health department wouldn't tell us if the person with TB is a student or faculty member, but they did say they are being held in quarantine.
A letter was sent out to people they think came in contact with that person, but they would not give us a copy.
Doctor Helen Morrow said if they alerted everyone about a TB case in the area, they'd be sending out letters weekly.
"We don't normally warn the whole population. It is in your community. Period."
Morrow says if more than ten percent of the students and teachers tested this week show signs of exposure, then more people will be notified.
"This does not take place in an hour like on CSI it does not take place in two days it does not take place in one week it actually can go on for months."
Still, high schools are a breeding ground for germs and parents think the school could, and should, do more in the future.
Rudd said, "Awful. We need to know what's going on. If they get in trouble or they get a suspension we get a notice about that so they need to be together on everything."
The first round of test results should be in on Friday.
School ends next week, but the health department has a group of investigators, and if more people need to be tested, they will track them down at home.
