LANHAM, Md. (CBSDC) — A case of active tuberculosis has been confirmed at a Montgomery County High School.
Watkins Mill High School in Gaithersburg sent a letter home to parents Thursday, informing them that the affected person is being treated and that there is no risk of additional exposure to students or staff.
The letter went on to say that tuberculosis is usually transmitted only after eight hours of close contact in a small room and that “a healthy person cannot contact tuberculosis from casual exposure such as passing in a hall or sitting in a cafeteria for an hour.”
Although the school believes the risk of any other students having contracted the sickness is small, TB officials within the county Department of Health and Human Services recommend testing for all students and staff who were in any class or after-school activity with the infected individual between October 2013 and January 2014.
The school says those who may need to be tested will be notified by early March. Nurses from DHHS will be available to provide free testing after that point.
