Precautions at the Samsung Medical Center in Seoul have been stepped up
"We apologise for causing great concern as Samsung Medical Center became the centre of the
spread of Mers," he said.
"This is entirely our responsibility and failing, as we did not properly manage emergency-room
staff."
Mr Song said he would review the suspension on services on 24 June.
More than 70 cases have been traced back to the hospital, authorities say.
Among them was an emergency ward orderly who worked for days after developing symptoms and came into contact with more than 200 people, officials said.
It is believed the orderly picked up the virus from an infected person who waited for days in various parts of the emergency ward, potentially exposing the virus to an estimated 900 staff, patients and visitors.
The World Health Organization (WHO) has warned that the outbreak is "large and complex" with
further cases expected, although it does not expect the outbreak to spread among the wider
community.
