SEOUL, South Korea — South Korea has added 1,092 new coronavirus cases in a resurgence that is erasing hard-won epidemiological gains and eroding public confidence in the government’s ability to handle the outbreak.

The national caseload has jumped by a quarter in the last two weeks alone, the death toll is rising and the number of sick patients is raising concerns of a shortage in intensive care beds.

South Korea had been seen as a success story against COVID-19 after health workers managed to contain a major outbreak in its southeastern region in the spring. But critics say the country gambled on its own success by easing social distancing restrictions to help the economy.
