School shuts down over
high school fears

TYNGSBOROUGH, Mass. - A Massachusetts Catholic school is shutting down for the week because a student has a probable case of swine flu.

The Archdiocese of Boston says the Academy of Notre Dame in Tyngsborough will cancel classes and all activities "out of an abundance of caution" while the school is sanitized.

Notre Dame has a co-educational elementary school for grades 1 through 8 with about 440 students, and an all-girls' high school.

Health officials are also trying to track down patients of Boston University's dental school who had contact with a resident diagnosed with a probable case of H1N1 flu.

Officials believe a dozen patients of BU's orthodontic clinic had contact with the female resident. Officials say they talked with 10 patients who are not showing any signs of the flu.
