The Sacramento County Department of Health and Human Services says about 150 Florin High School students will be tested for Tuberculosis this week.
A student at the school tested positive for the disease last week.
Doctor Olivia Kasirye is the County Health Officer. She says about 10 percent of people who have been exposed to tuberculosis get sick from the disease.
"The reason that we treat people with latent TB infection, is to prevent it from ever progressing to active disease. Because in a small percentage of people, they might progress to active disease depending on their body's immune system."
Testing will begin Tuesday. The County could have results by late Friday or early Monday.
Sacramento County is holding an event for parents who might be worried about the disease at the high school's library at six o'clock tonight.
