Tests conducted at Salt Lake's Hillside Intermediate School indicate 69 students have been exposed to tuberculosis, but the school still only has one confirmed case of the disease.
Health officials have tested 666 students, said Teresa Garrett, tuberculosis control officer for the Utah Department of Health. Salt Lake City-County Health officials offered free tests after a Hillside student was diagnosed with the disease.Students who test positive should undergo an X-ray. A positive test simply means a student has been exposed to the disease at some point in life. A healthy immune system generally keeps the disease in check, Garrett said.
Tuberculosis is a lung ailment caused by airborne bacteria spread by sneezing and coughing. The disease is treated with oral antibiotics.
