South Korea reported its first death from a new Coronavirus on Thursday while the mayor of a southeastern city urged his 2.5 million people to refrain from going outside as viral infections, linked to a church congregation, spiked.

The death of a previously confirmed patient in South Korea marked the world's ninth virus fatality outside mainland China. The Korea Centers for Disease Control and Prevention said the South Korean man, believed to be around 63 years old, died at a hospital on Wednesday and posthumously tested positive for the virus. It said authorities were investigating the exact cause of his death. The center confirmed 22 additional cases of the virus, raising the total in South Korea to 104.
