DURHAM -- Public health officials say a student from Northern High School in Durham has tuberculosis.

The student is getting treatment and has been isolated at home until they're no longer infectious.

School officials confirm parents of other teens who may have come in contact with the infected student have also been notified.

The Durham County Department of Public Health says TB is spread through the air when someone who is infected with the bacteria coughs, speaks, laughs, sings, or sneezes. 

“We are taking the necessary actions to identify students and staff of Northern High School who may have been exposed to TB,” said Arlena Seña, medical director, DCoDPH in a statement.  “We will be conducting initial evaluations and blood tests for TB at the school to make it easier on parents and students. We ask for patience as we work with Durham Public Schools on this communicable disease investigation.”

“We’re grateful for the health department’s support,” said Northern High School principal Dan Gilfort in a statement. “We’ve worked closely with them to make sure that every student who needs a doctor’s checkup has been identified.”

Another TB case was reported at UNC-Chapel Hill. It was reported Oct. 13.

Health officials say TB disease is treated by taking several drugs for six to 12 months. Those with a latent TB infection can take a preventative medication for four to nine months to prevent the disease later in life.
