The Warren County Health Department has confirmed the presence of several Campylobacter infections at Blair Academy, a private high school in Blairstown, where about 80 per cent of its 460 students board at the school.

Peter Summers, Warren County health officer, said that “a few” of the tests that were sent out to labs came back positive for campylobacter after approximately 30 people had reported becoming ill since mid-November.

Officials at Blair Academy could not be reached for comment, but Summers said he believed parents of students were notified of the infection within the last week or so.
