(New York Times) There are now more than 2,000 swine flu victims on college campuses, according to an American College Health Association survey. And as colleges welcome students back this month, they are keeping those infected with the H1N1 virus at a safe distance. On top of dispensing face masks, circulating lists of warning signs and encouraging contagious students to stay home, many campuses are roping off sick-student-only zones. Carnegie Mellon University designated a vacant sorority house for the infected. St. John’s University set aside a gymnasium. And Princeton did the opposite, reserving spaces for healthy students, so sick roommates can sleep in solitude. Swine flu is most prevalent at colleges in the Southeast and Northwest, according to the health association survey, with the largest outbreaks at campuses in Georgia, Mississippi, Pennsylvania, Tennessee and Washington. Of the 189 colleges that responded to the survey, more than half had experienced a swine flu case in the last week of August.
