The halls of Guilford High School will be empty Monday and Tuesday of this week. The entire school shut down because of what district officials call the "increasing spread of flu-like illness."
Nearly half of Guilford High School students were out sick Friday.
Meanwhile, a spokesman for the state Education Department has declared this the first "outbreak" of flu-like symptoms at a public school this year.
As many as 30 percent of the student body was out sick Thursday, and that number climbed to 42.5 percent on Friday.
Students and staff have been encouraged to avoid group gatherings.
Elementary and Middle Schools have not been impacted by the same numbers of ill students.
Education spokesman Thomas Murphy also says Brooklyn Elementary School in Brooklyn is the only other school in the state reporting increased absences because of swine flu-like symptoms.
