Texas county facing second TB case in one month

Nurses in Dallas County, Texas, will be offering tuberculosis testing for the second time this month to students and teachers that were exposed to a student who tested positive for the disease.

Though officials did not release the name or school the student belonged to, Dallas County Health and Human Services reported on January 26 that a Seagoville school student had come down with TB, according to DallasNews.com.

In the first case, diagnosed earlier this month, a North Dallas High School student was diagnosed with the infectious disease. The North Dallas student, whose name was never released, had left the school in October for health reasons and later died of an unrelated cause.

“We are looking into the possibility that the two cases might be linked, but preliminary indications are that they are not,” Blanca Cantu, a spokeswoman for the health department, said, according to DallasNews.com.

Because of medical confidentiality rules, no further information about the case has been released.

“Our TB staff is working hard to determine the extent of possible exposure to students and staff where this student attended school,” Zachary Thompson, the department’s director, said of the second case, according to DallasNews.com.

Cantu said pediatric cases are uncommon.

“The population most commonly affected by TB includes working adults and retirees,” Cantu said, DallasNews.com reports. “From time to time, we do see pediatric cases with TB, but it’s a small number of patients.”
