A probable case of tuberculosis at Bryan Adams High School was reported to Dallas County health officials last week.
County health officials say a Dallas high school student has a probable case of tuberculosis.
The case at Bryan Adams High School was reported to the Dallas County Health and Human Services Department on Friday.
The county sent notes home to parents that said the risk of exposure was low but that certain students would need a skin test on Tuesday.
Dr. Garry Woo, the county's tuberculosis elimination medical director, said quickly ordering the tests was the biggest concern.
"Because school was going to end soon, we felt it was urgent to conduct the contact investigation for the simple fact that it would be difficult to find students once they are dismissed from school," he said.
The skin test results will be read Wednesday or Thursday. Follow-up testing will be done if necessary.
Despite recent tuberculosis cases in Ennis and at El Centro and Tarrant community colleges, the bacterial infection is largely under control in Dallas County and across the country, Woo said.
Tuberculosis is largely under control in Dallas County and across the country, Woo said. He said he is not overly concerned about the infection making a comeback.
"It hasn't been out of line," Woo said. "In fact, tuberculosis in the United States and Texas has dropped significantly in the past 10 years."
Dallas County had 195 confirmed cases of tuberculosis in 2009, 188 cases in 2010 and 206 cases in 2011.
