SEOUL, South Korea — South Korea has added more than 1,000 infections to its coronavirus caseload for the second straight day amid growing fears that the virus is spreading out of control in the greater capital area.

The Korea Disease Control and Prevention Agency on Thursday said the COVID-19 death toll was now at 634 after 22 patients died in the past 24 hours, the deadliest day since the emergence of the pandemic. Among 12,209 active patients, 242 are in serious or critical condition.

Nearly 800 of the 1,014 new cases were reported from the densely populated Seoul metropolitan area, where health officials have raised alarm about a looming shortage in hospital capacities.

Thursday was the 40th consecutive day of triple digit daily jumps, which brought the national caseload to 46,453. The country reported 1,078 new cases on Wednesday, its largest daily increase.

The viral resurgence came after months of pandemic fatigue, complacency and government efforts to breathe life into a sluggish economy.

Officials are now mulling whether to raise social distancing restriction to maximum levels, which could possibly include bans on gatherings of more than 10 people, shutting tens of thousands of businesses deemed non-essential and requiring companies to have more employees work from home.
