RICHMOND, Texas – A total of 20 people tested positive for tuberculosis after two rounds of testing at George Bush High School, officials announced Wednesday.

Fort Bend County Health and Human Services officials said 10 people tested positive after the first round of testing on June 19, and 10 more tested positive during the second round of testing on Aug. 3.

Officials said just because a person tests positive for tuberculosis does not mean they have an active case of the disease. All of those who are infected are receiving treatment aimed at preventing an active case, officials said.

Tuberculosis is a disease of the lungs that can affect other organs, officials said. It is not as easily spread as a cold or flu, but it can be spread by a cough or sneeze.

Symptoms include a persistent and productive cough lasting more than two weeks, unexplained fevers, night sweats, unexplained weight loss or coughing up blood, officials said. Anyone with these symptoms should immediately see their health care provider.
