State health officials say more than 80 people exposed to a southern Indiana student with a confirmed case of tuberculosis have now tested positive for the disease.
The State Department of Health said Friday that 85 people have tested positive to TB in skin tests, up from 54 positive tests on Wednesday.
Those individuals who've tested positive for the TB bacteria don't have tuberculosis, but will receive antibiotic treatment so that symptoms don't develop and to prevent the infection from spreading to others.
The 85 individuals who've tested positive to date had contact with a student with a confirmed case at Rock Creek Community Academy in Sellersburg, about 10 miles north of Louisville, Kentucky, or at a church in the area.
That student is isolated and responding well to treatment.
