Jung Il Woo has recently recovered from herpes labialis.
His label confirmed that he was diagnosed with it in December, but he has currently recovered and is filming 'Haechi' without any problems. His label explained that he lost 14 kg (31 lb) in 1 month for his new character. Because of the sudden weight loss, his immune system lowered, resulting in his herpes.
He suffered from it for 2 weeks, and still has a cut from it. He is recording through makeup and CG.
His drama 'Haechi' will start airing on February 11th.
