SEOUL, South Korea – South Korea on Monday reported 161 more cases of a new virus that has spread rapidly around a southwestern city, bringing the nation's total to 763 cases a day after the president called for “unprecedented, powerful” steps to combat the outbreak. Two more deaths were confirmed, raising South Korea's death toll to seven from the COVID-19 illness, which is caused by a newly identified coronavirus that has infected tens of thousands of people, mostly in China. More than 140 of South Korea's new cases were in and near the city of Daegu, where most of the country’s infections have so far occurred.
