The number of fatalities in the largest outbreak of the virus outside Saudi Arabia remained at 10 as of June 12, the Health Ministry said.

Mediheal Hospital will remain shut until June 23, a Seoul City spokesman.
A total of 52 health care facilities including 18 in Seoul and 16 in the surrounding Gyeonggi Province have been exposed to the virus.
Pyeongtaek St. Mary's hospital, where the first wave of 37 patients were diagnosed, will also remain closed until Friday, based on the incubation period for the disease.
But Samsung Medical Center, where 58 out of the 126 confirmed cases contracted the disease - the largest single outbreak - remains open after being sanitized.
More than 3,800 people who came into close contact with those infected are under quarantine, either at their homes or at healthcare facilities.
