Due to growing concerns about swine flu, some universities have begun canceling study abroad programs in Mexico, including the University of Minnesota, which on Tuesday announced that the 21 students currently in Mexico were being advised to return home and that academic programs beginning in late May had been canceled (affecting 52 students). Various news outlets have also reported the canceling of programs at North Carolina State University and the University of Wisconsin at Eau Claire, to name a few examples. The Centers for Disease Control and Prevention this week recommended that U.S. travelers avoid all nonessential travel to Mexico.
