In the largest MERS outbreak outside Saudi Arabia, South Korea reported two fatalities and three new cases, taking the country's death toll to 27.
The two men -- aged 84 and 87 -- died from Sunday night to Monday morning of Middle East Respiratory Syndrome, the health ministry said, adding both had been battling cancer.
They contracted the virus at Samsung Medical Center in Seoul and Daecheong hospital in the western city of Daejeon and were diagnosed on June 9 and 12, respectively.
The ministry also reported three more cases of the disease to bring the total number of those infected to 172, including 27 who have died.
The three included two patients at Samsung hospital and Konkuk University Medical Center in Seoul and one caregiver at Daecheong hospital.
Samsung -- a major hospital where more than 80 patients, families and medical workers have been infected -- suspended most services on June 14 to stem the spread of the virus.
Fourteen patients were in critical condition, the ministry said, adding 50 people had recovered and were released from hospital so far, including seven from Saturday to Sunday.
The spread of the virus has slowed since the first two weeks of June, when the number of patients often grew by double digits including a daily record of 23 on June 7.
On Saturday the authorities reported no new cases for the first time in 16 days.
The outbreak began on May 20 when a 68-year-old man was diagnosed after returning from a trip to Saudi Arabia.
Since then the potentially deadly virus had spread at an unusually rapid pace, sparking public alarm that prompted the temporary closure of thousands of schools and trip cancellations by more than 120,000 foreign tourists.
Most schools have reopened except for five in Gyeonggi province surrounding Seoul, the southern port of Busan and the southeastern city of Daegu.
