Vocal duo December will be postponing their activities, as member Yoon Hyuk has been diagnosed with H1N1 (a.k.a, 'swine flu'). On January 12th, his agency revealed that Yoon Hyuk was admitted to the hospital with a high fever and severe coughing.  They stated, "We weren't able to contact Yoon Hyuk on the 11th, so his manager went to his house and found him on the floor with a high fever.  His manager carried him all the way to the hospital, and Yoon Hyuk was diagnosed with swine flu.  He's currently hospitalized and is receiving treatment." They continued, "He's had to juggle a schedule based off two hours of sleep a day in order to make all of his broadcast and concert appearances.  His immune system has weakened due to fatigue. Until he fully recovers, he'll be focusing on his treatments.  December's broadcast appearances will be postponed until then." Source + Photo: Star News via Daum
