The Dallas County Community College District and Dallas County Health and Human Services are investigating a single suspected case of tuberculosis at El Centro College.
Students who attend three classes with the individual involved are receiving written notification during either their afternoon class on Monday or morning classes on Tuesday.
Tuberculosis is spread through the air, but generally those who are at the highest risk of infection are those who have spent several hours with the infected person. Dozens of students may have been exposed, officials said.
Only those El Centro College students who attend those classes and may have been exposed should be screened for TB.
Those students impacted can receive a routine TB skin test administered by DCHHS staff members on either Wednesday from 1 to 4 p.m. in room 269, Building B, or on April 24, from 9 a.m. to noon in the same location.
Students who attend those classes and have questions can contact Ken Johnson, the college nurse, at 214-860-2113.
They also can call their community physician or the Dallas County Health and Human Services TB Clinic at 214-819-2071 for information about TB, which is a preventable and treatable illness.
