JACKSONVILLE, Fla. -- One student has tested positive for exposure to tuberculosis at Andrew Jackson High School, according to the Duval County Health Department.

Exposure is not the same as having the disease.

Two students tested positive for the having the disease earlier this month. The alert prompted the testing of about 100 students and faculty who came in contact with the students who had TB.

Health experts have completed tests on 68 people so far. The one person exposed to TB has what's called latent tuberculosis infection.

No new active cases have been identified.

TB is a disease caused by germs spread through the air between persons in close contact through the air. TB germs are put in the air when a person with TB, a disease of the lungs or throat, coughs, sneezes, speaks or sings. People who breathe in the air containing TB germs can become infected.

TB is diagnosed by a skin test or blood test, administered by a health care provider or local health department. A positive test usually means the person has been infected with the TB germ; however, it does not necessarily mean the person has active TB disease. Additional tests, such as an X-ray or sputum sample, are needed to determine if the person has active TB disease. TB can be easily cured through proper medical treatment.
