Provost Joseph Steinmetz 3/19/14 The recent outbreak of mumps on the Columbus campus has all of us concerned. While relatively few students have been affected, any number is too large, and the university is taking precautions to ensure that the outbreak is controlled as rapidly as possible. Those precautions include Student Health Services and Columbus Public Health’s urging students who have fallen ill with mumps to stay home and avoid school, work, and other public settings for five days after their symptoms appear. This request means that affected students will be unable to attend school, perhaps for several days. If you have such students in your classes, I ask that you offer them all reasonable accommodation to make up any quizzes or exams, labs, class activities, or other work they’ve missed while sparing their classmates from possible infection. If you are a course supervisor, please make sure this information is communicated to your instructional staff.
