Earlier reports said a 61-year-old South Korean female, who has no history of travelling abroad and has not been in contact with other infected people, was infected. She was screened at a public health centre in Daegu, and the test showed the presence of the virus. She is now in quarantine.
According to the KCDC, 16 people have recovered and have been discharged in South Korea, so there are still 66 people undergoing treatment. Another 1,633 are being tested.
Chinese health authorities earlier reported a total of 2,118 fatalities from the new virus in mainland China, with more than 74,576 people infected.
An outbreak of pneumonia caused by a new strain of coronavirus originated in the Chinese city of Wuhan last December. It has since spread to more than 25 countries around the globe.
The World Health Organisation (WHO) has designated COVID-19 as the official name of the new virus and declared a global health emergency over the coronavirus outbreak.
