JYJ's Jaejoong has updated fans on the condition of fellow member Yoochun's eye infection.

Jaejoong took to his Twitter and wrote, "For JYJ membership week, the C-jes family worked really hard; fans, please enjoy to your heart's content~. Although I felt very bad for Yoochun after seeing his [swollen] face today, he was smiling widely while watching the exposition [progress]~. Don't worry too much ^^."

Along with the tweet, Jaejoong uploaded a picture of himself and fellow member Junsu standing in front of a huge JYJ poster. The event at which the picture was taken was at the 'JYJ Membership Week' exposition organized by JYJ and C-Jes Entertainment.

During this event, we reported that Yoochun did not take questions from reporters. It has been revealed that the reason behind this is because Yoochun caught an eye infection, and as a result his face became swollen. Specifically, Yoochun seems to have an acute case of conjunctivitis, also known as the pink eye or Apollo eye, caused by internal bleeding. It is a common eye infection, which induces a stinging kind of pain.

Due to these events, it seems that Jaejoong found it necessary to communicate to his fans about Yoochun's health and his thoughts concerning the exposition.

Fans who read the tweet replied, "So Park Yoochun-ssi had conjunctivitis," "I like that Jaejoong-ssi [took the time to] deliver this piece of news to us like that," and, "Even though you probably caught the eye infection after working so hard, [please] get well soon."
