ED nurses taking care of MERS-CoV-infected patients should be aware that burnout is higher for nurses in their divisions than nurses in other hospital departments and that job stress is the biggest influential factor of burnout. To be ready for the outbreak of emerging contagious diseases such as MERS-CoV, efforts and preparations should be made to reduce burnout. Job stress should be managed and resolved. Working conditions for mitigating job stress and systematic stress management programs should be provided, and hospital resources for the treatment of MERS-CoV need to be reinforced. Moreover, promoting support from family and friends is required.

Similar to other emerging infectious diseases, Middle East respiratory syndrome outbreaks may occur in other countries. The results of this study can be used to develop and apply efficient and feasible Middle East respiratory syndrome education programmes for nursing students during Middle East respiratory syndrome outbreaks.

Through this study, we obtained information on emergency nurses' ethical problems during the Middle East respiratory syndrome-coronavirus outbreak and identified the factors that influence them. As found in this study, nurses' ethical problems were influenced most by cognitions of social stigmatization. Accordingly, to support nurses confidently care for people during future health disasters, it is most urgent to promote appropriate public consciousness that encourages healthcare workers.

Preventive behavior against emerging infectious diseases such as MERS-CoV was found to be affected most significantly by attitude and risk perception. It is crucial to provide nursing students with information or knowledge, but it is also important to help those in nursing education recognize that active preventive behavior can prevent this infectious disease and stop its spread.
