Kim Jae-joong, a member of the JYJ boy band, posted on his Instagram account with 1.9 million followers that he was hospitalized after coming down with the virus.
“I have been infected with COVID-19. It is a result of my negligence, disregarding the cautionary words of the government and my friends,” he said.
After several hours, the 34-year-old Asian pop icon edited the post to say he had gone too far for “April Fools’ Day”, but thanked his fans who had worried about him.
“I don’t think of this as an April Fool crap … I just wanted to tell you that protecting yourself protects the valuable people around you,” Kim said.
