PUBLIC health officials are investigating a case of TB (tuberculosis) at a Newport high school.

A "single" case of the infection was discovered at The John Frost School, in Duffryn, Public Health Wales (PHW) confirmed today, Tuesday.

"As a precaution all pupils and teachers who had contact with the individual will be offered screening for TB," PHW said in a statement.

"There is nothing to suggest that the case contracted TB at the school, rather they have attended the premises when they unknowingly had the infection.

"No outbreak has been declared."

James Adamson, acting consultant in health protection at PHW, is chairing a multi-"agency incident management team" which includes Aneurin Bevan University Health Board and Newport City Council.

He said: "Following established infection control procedures we have identified individuals who may have had contact with the individual concerned, these individuals have been contacted and offered screening for TB which is easily treated with a course of antibiotics."

Local GPs have been informed of the case, he added.

Dr Adamson said the notification of local GPS was "a routine process" and if any other TB infections are found as a result, "appropriate treatment will be offered".

"TB is difficult to transmit," he added. "It requires close and prolonged contact with an infectious individual for a person to become infected.

"In this instance, and to limit the potential spread of infection, we are treating all pupils and teachers who may have had contact with the individual as close personal contacts.

"I would stress that the risk of infection with TB to the general public remains very low however, we encourage parents, pupils and staff members to be aware of the symptoms."
