A student at La Plata High School has been diagnosed with tuberculosis (TB), the Charles County Department of Health confirmed.

The school system is working closely with the health department to ensure there is no further risk in the school.

TB is a bacterial illness that responds well to proper medical treatment, but it can be spread through the air by coughing or sneezing. Generally, a person must have prolonged exposure to TB before contracting the infection.

Additional information about tuberculosis is available on the Department of Health website. A fact sheet is also available on the school system website.

The school system is working to determine who, among students, teachers and staff, may have had prolonged exposure to the student who contracted the disease. They will receive an exposure letter and a testing consent form, which the health department will provide.

Yesterday, La Plata emailed and mailed an information letter home to all parents. Questions can be directed to your family physician or the Charles County Department of Health’s Communicable Disease Control Program at 301-609-6900, ext. 6025, from 8 a.m. to 5 p.m., Monday through Friday.
