Nearly 70 students and staff at Jefferson City High School have many months of medical treatment ahead. They’ve been exposed to tuberculosis. While most of the exposures won’t turn in to active cases, TB section chief for the Missouri department of health, Vic Tomlinson, says they’ll all have to stick to a drug regimen for six to nine months. Only 10% of Missouri’s exposure turn into active cases. Fewer than 1% of the active cases are fatal.
