South Korea has its first confirmed case of swine flu, media outlets in the country reported on Saturday. According to the Yonhap news agency, final tests confirmed a 51-year-old woman has the disease after recently returning from a trip to Mexico. She had been listed as a probable case since Tuesday. Officials have said she had recovered enough to consider being discharged from a hospital where she remains quarantined. Officials declined to confirm the report, saying they will make a formal announcement later.
