Fort Myers, Fla - A group of students at Edison State College testing positive for a germ that could lead to tuberculosis. The results came weeks after a student at the school was diagnosed with the disease.

The Lee County Health Department says the latest group was exposed to the student, but that they have may have caught the germ at some point earlier in life. 

"The only person who can transmit TB is someone who is sick with TB", said Dr. Judith Hartner, the Director of county's health department.

51 people at the school were tested and 7 came back positive for TB bacteria. According to the health department, on average, just 1 in 10 infected people become ill with TB. 

Health officials say the most recent group do not pose a threat to students. Dr. Hartner will be answering questions at the school on Thursday at 3 p.m. and Friday at 1 p.m.
