South Korea has reported more than 120 new virus cases and the country's fourth fatality, raising the total number of those infected to 556.
The fresh national figures for the disease that emerged in China in December came as the number of viral infections soared mostly in and around the southeastern city of Daegu, where they were linked to a local church and a hospital. Thousands of worshipers have been screened for the virus.
The Korea Centers for Disease Control and Prevention says 113 of the 120 new cases were reported in Daegu and its surrounding province.
