Concern about the spread of SARS is affecting college campuses across the country and in Minnesota. So far, three universities in the U.S. have said they do not want families from SARS affected countries to attend their graduation ceremonies, and one high profile university is banning some Asians from attending summer school. Minnesota colleges are just starting to develop their own SARS policies. Officials say while it's wise to be cautious, it's important to keep fear of SARS in check.
