A group of students at Bellaire High School will be screened for tuberculosis after the City of Houston determined that one person at the school is undergoing testing and treatment for a suspected case of the bacterial infection, MyFoxHouston reported.

Principal Michael McDonough sent a letter home Monday to parents of students at the school, informing them of the situation.

“I recently met with representatives from the City of Houston Health Department,” McDonough wrote. “They informed me that an individual at our school is being evaluated and treated for a suspected case of tuberculosis (TB). Fortunately, the individual is recovering and feeling much better.”

McDonough added that so far, there have been no other cases of TB identified at the school.

“We are taking this situation seriously and will be working closely with the Houston Health Department to identify any student or staff that should be tested for TB infection,” he wrote.  “…Determination of who needs testing is based on the type of exposure a student or staff has had to the sick individual. If your child is recommended for testing, a separate letter and consent form will be sent home next week.”
