Newberry Academy's decision to close came as the number of suspected swine flu cases in Mexico climbed past 1,600 and death toll past 100. At least 11 cases has been confirmed in the U.S.
Newberry Academy officials said in a statement that seniors were in Mexico earlier this month and some had flu like symptoms when they returned. Calls to the school rang unanswered this morning.
State Department of Health and Environmental Control spokesman Jim Beasley said test results on the students could come back as early as this afternoon. The agency has stepped up efforts to investigate all flu cases in South Carolina. There have been no confirmed swine flu cases in the state.
