No case of infection with the Middle East Respiratory Syndrome (MERS) was reported in South Korea on Monday, while no death was added for six straight days, the health ministry said.

The total MERS contagion cases were unchanged at 186, according to the Ministry of Health and Welfare.

The spread of the deadly viral disease showed signs of abating because only one case was added in the past four days through Sunday. No case was reported for four days through July 1.

The South Korean government planned to declare an end to the MERS spread if 28 days, or twice the 14 days of incubation period, pass by without any case of MERS infection reported.

No death was reported for six days in a row, leaving the death toll at 33 and the fatality rate at 17.7 percent.

One more patient was discharged from a hospital as he completely recovered after being infected. The discharge number increased to 117.

Excluding the dead and those discharged, 36 patients are under treatment. Among them, 12 are still in unstable conditions.

The number of those quarantined reduced from 982 on Sunday to 907 on Monday.
