This paper was a retrospective study that the medical records of patients who have undergone MERS
screening to find out whether the proper measures have been taken by Jeju University Hospital and related
organizations in blocking and screening the suspicious MERS patients in Jeju Island in 2015. As a result,
it was found that there were inappropriate points such as inspecting even if it did not meet the screening
indications of the Disease Control Headquarters. It revealed that not only Jeju University Hospital but also
related organizations showed the same results. Also, there was a tendency to increase the number of
screening tests every time media reports about MERS appeared. It is interpreted that not only the public
but also the doctors have also distrusted the government's response guidelines and thought that there was
some fear, and applied the wide range of examination indications for the suspected patients themselves. In
order to respond more effectively in the event of biological disasters in the future, efforts should be made
to establish a response system by the joint efforts of the government as well as related organizations so
that the public can be trusted.
