The arrival of spring break was cause for concern as well as celebration. Many students left campus with active conjunctivitis or as carriers of the outbreak strain, and some students traveled to places that are popular vacation spots for college students. The outbreak of conjunctivitis at Princeton, caused by the same strain identified at Dartmouth, suggests that transmission occurred between the two campuses. Students from these two Ivy League schools compete in sporting matches and participate in a variety of joint social events. Outbreaks at other college campuses may still occur.
