South Korea urges more testing, quarantines as coronavirus cases hit 5-1/2 month high

South Korean health authorities warned on Friday that a cluster of coronavirus infections in the capital Seoul was threatening to spread after thousands of people attended a rally by conservative political groups last week.

The Korea Centers for Disease Control and Prevention (KCDC), reported 324 new cases as of midnight Thursday, the highest daily count since March 8. That took the country’s total to 16,670 cases, with 309 deaths.
