The city health department is testing students and staff at a Queens high school for tuberculosis.
The department says an individual at Hillcrest High School was recently exposed to the bacterial infection.
The person is recovering.
As many as 170 students and six staff members were tested Tuesday.
While officials say there is no health risk to anyone at the school, some students say they are nervous.
"Now all the students are, like, really paranoid. And, like, every time I cough, my friend would be like 'Stay away from me,' cause they'll think I have tuberculosis. So we're all really paranoid," said one Hillcrest student.
Officials say TB cases are on the rise in the city for the first time in a decade.
The DOH says 656 cases were reported last year, up from 651 the year before.
