An Olathe school isn’t taking any chances and is testing about 350 students and staff for tuberculosis after they came into contact with an infected student.

The director of the Johnson County Department of Health and Environment says there’s a very low chance the student spread the disease to others at Olathe Northwest High School.

The screenings this week will involve students and staff having their blood drawn. The student diagnosed last week with tuberculosis hasn’t returned to school and is being treated at home.

Parents and students attended a public meeting to learn more about tuberculosis, an airborne disease that can be spread by coughing and sneezing. Symptoms include a bad cough for three weeks or longer, chest pain, weakness or fatigue, and coughing up blood.
