The Health Department tested 170 students and six staff members who might have been at risk at the Queens school Tuesday as a precaution.
“Given that the person with TB is receiving treatment, there is no health risk to students or staff currently at the school,” a department spokeswoman said.
Tuberculosis cases are on the rise in the city for the first time in a decade, health officials said. They increased 1 percent from 651 in 2012 to 656 in 2013.
Most people infected were foreign-born, living in Flushing, western Queens and Sunset Park in Brooklyn, according to the Health Department.
Officials said 19 out of 100,000 people have contracted the disease in Corona, Woodside, Elmhurst, Jackson Heights and Maspeth and 15 out of 100,000 in Flushing.
“Many are likely infected in their country of origin and developed TB after entering the U.S.,” Health Commissioner Dr. Mary Bassett said.
Smokers and people with diabetes or HIV have a higher chance of getting tuberculosis and should be tested for the disease, Bassett said.
Tuberculosis, which usually affects the lungs, spreads from person to person through the air.
