South Korea confirmed the death of yet another patient, thus taking the death toll to 16. Officials also reported five new cases in the country, making it the largest outbreak outside the Middle East.
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.
Meanwhile, health analysts have blamed South Korea's largest health service provider Samsung Medical Center as the reason for the spur in cases. Nearly 70 cases have been traced back to the hospital.
Issuing a public apology, Samsung Medical Center's president Mr Song Jae-hoon told reporters that the hospital would stop treating outpatients and admitting new patients to prevent further infections among patients and medical staff.
"We apologise for causing great concern as Samsung Medical Center became the centre of the spread of Mers," he mentioned.
