ユッキーナがA型インフル、自宅で療養中
タレント、木下優樹菜(21)がA型インフルエンザでダウンしたことが6日、所属事務所のHPで発表された。 5日夕に38度を超える高熱を出し、都内の病院で検査したところ、A型インフルと診断された。担当医の指示で、現在自宅で安静にしており、完治するまで仕 事を休んで療養に努めるという。7日に出演予定だった福岡・中村学園大の学園祭はキャンセル。レギュラー番組の出演は体調を見て決める。
Basically, it says that talento Kinoshita Yukina (21) has been diagnosed with Influenza A on the 6th (today). On the evening of the 5th she had a 38 C fever and after an examination at the hospital she was diagnosed with the flu. On doctors advice, she's curently at home to recover. All her work has been cancelled to not infect other poeple.
Wow, I don't hope she infected others, because she appaers on tv-shows with a lot of other popular actors/singers/comedians. She's probably also in a relationship with FUJIWARA's Fujimon, so I don't hope she infected him. Same goes for the Hexagon Family with whom she had a big live concert last week. A lot of people of the Hexagon Family are very busy at the moment, like Kamiji Yusuke, who's currently promoting his new single and is also appearing in the drama Gyne. And of course other people like Satoda Mai, Suzanne, Tsuruno Takeshi, misono, Yaguchi Mari, Tsuji Nozomi, Shinagawa Shouji, Ungirls and many others. If she got a few of those people infected then I think there will be some trouble. XD
Get well soon!
