On Thursday, Lost actor Daniel Dae Kim made the following announcement on his Instagram and Twitter accounts: “I wanted to let you know that yesterday I tested positive for COVID-19, the disease caused by the coronavirus.” While quarantined at his home in Honolulu, the 51-year-old actor detailed his symptoms, diagnosis, treatment, as well as many of  his personal convictions during a ten-minute video.

Initially, Kim felt fine as he was working on the set of the NBC series New Amsterdam while in New York over the course of weeks. “Ironically,” he says, he was portraying a doctor who “gets recruited to help patients during a flu pandemic,” in the medical series. 

“It’s important for you guys to know that I was asymptomatic during all of this time,” he said. But when the shoot was cancelled due to the fast-spreading, highly contagious virus, Kim took a flight home to Hawaii. Before the plane landed, he noticed a “scratchiness” in his throat. “To be safe, when I got home I quarantined myself in a room in the house and tried to rest on my own,” he shared, and as his doctor advised, he monitored his symptoms.

Unfortunately, things took a turn for the worse when Kim’s symptoms became more severe—he experienced tightness in his chest, a fever, and body aches. So his doctor advised him to get tested for COVID-19 as soon as possible. Thankfully, a nearby drive-through testing facility had just opened up in Honolulu. But getting tested was not fun. “They shove a huge swab into your nose and into your throat,” Kim explains. “But it was worth it.” Before the results came in, Kim’s doctor told him to start taking medicine. Fortunately, drinking plenty of liquids for days and taking the medication seemed to do the trick in Kim’s case. He’s well on the road to recovery.

But Kim anguishes over the cast, crew, or other individuals he may have inadvertently and unknowingly infected along the way. Everyone working on The New Amsterdam has been put on notice of their possible exposure to the virus. Also, Kim was relieved to hear that his family members tested negative for COVID-19. 

Kim expressed much gratitude towards the healthcare professionals who are bravely working to help the afflicted and trying to contain the pandemic. But as for some of the younger folks who continue to live a more carefree lifestyle during the crisis, Kim has a message:

“For all those out there, especially teenagers and millennials who don’t think this is serious, please know that it is. And if you treat this without care, you are potentially endangering the lives of millions of people including your loved ones.” He urges everyone to follow the CDC’s guidelines of thorough and frequent hand washing, not touching your face, maintaining ample social distance, and self-isolation as needed. 

Born in South Korea, Kim grew up in New York and Pennsylvania. He earned a MFA from NYU’s Graduate Acting Program and went on to appear in a steady stream of popular TV shows including CSI: Crime Scene Investigation, The Good Doctor, Charmed, The Shield, Seinfeld, ER as well as film roles in Spider-Man 2, Crash, and Hulk. But the actor is best known for playing Jin-Soo Kwon in the ABC series Lost and Chin Ho Kelly in the CBS reboot Hawaii Five-0.

Daniel Dae Kim joins the growing list of other celebrities who’ve contracted the disease including actors Idris Elba, Tom Hanks, and Rita Wilson; NBA players Rudy Gobert, Donovan Mitchell, and Christian Wood; and Sophie Gregoire Trudeau, the wife of Canadian Prime Minister Justin Trudeau.
