About 85 students at George Washington University are suffering from norovirus, which typically leads to several uncomfortable days, but is not life-threatening, The Washington Post  reported. Students with norovirus tend to experience diarrhea, vomiting, nausea and stomach cramps. Close quarters in which college students tend to live make it easy for the norovirus to spread. In New Jersey, officials at Princeton and Rider Universities  report that outbreaks on their campuses last week appear to be subsiding. At Huntington University, in Indiana, officials are dealing with an outbreak of head lice affecting students in four dormitories, The Journal Gazette  reported. Officials believe that the source of the list is a group of students who were on a trip to India in January.
