The purpose of this article was to investigate the issues related to nursing students' clinical practicum when severe contagious diseases occur. Based on the concept that patient-benefit must come first, the authors suggested that nursing students should remain on duty even if there were an outbreak of a severe contagious disease. The authors also discussed relevant issues in terms of professional roles and the safety of the learning environment. The problems identified and the proposed strategies for solving them are outlined in this article. There is no single strategy applicable to all conditions, however. Finally, the authors urge schools and hospitals to develop effective communications and close cooperation and to remain well informed about severe contagious diseases.
