Popular talk show host and former interviewer for CNN  Larry King have tested positive for Covid-19, according to a source close to his family.

King, 87, is hospitalized at Cedars Sinai Medical Center in Los Angeles for more than a week now, the source reported. Due to protocols at the hospital, King's three sons have not been allowed to visit him, according to the source. King, who has Type 2 diabetes, has faced a series of medical issues over the years, including multiple heart attacks and quintuple bypass surgery in 1987. In 2017, King was revealed to be diagnosed with lung cancer and successfully underwent surgery to treat it. He also underwent a procedure in 2019 to address angina.

His medical issues inspired him to start the Larry King Cardiac Foundation, a non-profit organization that aimed at helping those without health insurance afford medical care.

King used to host CNN's "Larry King Live" for 25 years, interviewing presidential candidates, celebrities, athletes, movie stars, and everyday people. He retired in 2010 after taping more than 6,000 episodes of the show.

But he couldn't stay off the television scene for too long. In 2012, he became the host of "Larry King Now," a thrice-weekly show on Ora TV, an on-demand digital network he co-founded with Mexican telecommunications mogul Carlos Slim.

Last year, two of King's adult children died within weeks of each other. His son, 65-year-old Andy King, passed away from a heart attack in late July, followed by King's 52-year-old daughter Chaia King, who died in August shortly after she was diagnosed with lung cancer.
