SINGAPORE/SEOUL -- Authorities across Asia are taking bolder action to contain the new coronavirus, in some cases going as far as to make patients' movements public to warn anyone who may have come in contact with infected people.
South Korea has focused on tracking and disclosing where patients went after they developed symptoms, using credit card histories and mobile phone data. People who came within 2 meters of patients are urged to stay home, with the government shouldering any lost wages.
