LAFAYETTE — About 200 people at Lafayette High School need to be tested for exposure to tuberculosis after a suspected case of the disease was reported there earlier this week, said Dr. Tina Stefanski, regional public health director on Wednesday.

Tuberculosis is a lung disease that can be transmitted by sharing the same space with an infected person for an extended period of time.

The school system notified Lafayette High parents Tuesday of the suspected tuberculosis case at the school and that those students identified as being at risk of exposure would be sent home with a letter Wednesday about exposure testing to be conducted by the Office of Public Health on Monday and Tuesday.

Stefanski said the exposure testing is a precaution and tuberculosis has not been confirmed at this time.

She said, “It could be months or years before someone exposed actually develops active tuberculosis.”

“The exposure test will identify whether someone was exposed to TB, so we can give medication and prevent them from developing active disease,” Stefanski said.

Stefanski said the 200 people identified for testing include faculty, students and staff at the school.

She encouraged parents to contact the public health office at (337) 262-5311, if they have any questions.
