"We have to wait and see how fast they improve their health. Until then, we can't give an answer on the group's appearances on music programs."

Got7 had been booked for television appearances on the Korean Broadcasting System program "Music Bank," Munhwa Broadcasting Corporation's "Music Core," and Seoul Broadcasting System's "Inkigayo" (or "The Music Trend") just in this week alone.

Got7 vocalist Jr. was the first to feel symptoms of swine flu.

The 19-year-old singer was reportedly taken to the hospital on Monday after complaining of a high fever and feeling achy.

One hospital staff member assured fans they were doing all they could for Jr., according to the publication eNEWS.

"Since we have to be watching for the improvement of his health, we plan on focusing more on his body's condition," the staff member said.

Jr.'s bandmates Youngjae, 17, and JB, 20, reportedly started feeling their own symptoms on Monday, when they were diagnosed with also having swine flu.

A seven-member hip-hop boy band that debuted on JYP Entertainment in 2012, Got7 is currently in the midst of promoting the "Got It?" EP, released on Jan. 20.

The music video for their new single "Girls Girls Girls" was released on Jan. 15.

According to the US Centers for Disease Control and Prevention, swine flu symptoms include a fever, cough, sore throat, body aches, a headache, chills and fatigue.

When left untreated, it has been known to lead to death through respiratory failure or pneumonia.
