Johnson County and Kansas health officials say a student at an eastern Kansas high school has been diagnosed with tuberculosis.

The Olathe Northwest High School student was diagnosed Tuesday and is being treated. The student, whose age and gender weren’t released, will not attend school for at least two weeks.

Health officials say they’re working to identify students and employees who should be screened for the disease. The deputy director of the Bureau of Disease Control and Prevention predicts there probably will be around 300 screenings.

Tuberculosis 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.

People with the disease are most likely to spread it to others they have prolonged contact with.
