SOUTH KOREA-FIRST CASE OF SWINE FLU.

Seoul: Authorities said a South Korean woman has tested positive for swine flu in additional examinations after travelling to Mexico, making her the country’s first "probable" case.

The Korea Centers for Disease Control and Prevention said final tests are still necessary to confirm whether the 51-year-old has swine flu.

The woman has remained quarantined since returning from a trip to Mexico on Sunday. She contacted authorities upon her return, complaining of high fever, cough and a runny nose.

All 315 others on the same flight from Los Angeles, and about 40 people living together with her at an unidentified "institution" were being tested, but officials says none have shown positive.

They refused to say where she was living, citing privacy.
