South Korea said on Tuesday it will open school classes online next week and reschedule its annual college entrance exams slated for November as concerns persist over the coronavirus and small outbreaks continue to emerge.

The country has postponed the beginning of all schools' new semester three times from early March to April 6 amid a rise in confirmed virus patients.

After a big early outbreak, South Korea has largely managed to bring down its daily number of new cases to around 100 or less, but infections from small clusters including churches, hospitals and nursing homes, as well as imported cases, continue to arise.
