The 68-year-old talk show host shared the news Monday in a posting on her verified Instagram account.
Osbourne wrote that she she had been briefly hospitalized with the contagious disease.
“I wanted to share I’ve tested positive for COVID-19,” her Instagram posting read. “After a brief hospitalization, I’m now recuperating at a location away from Ozzy (who has tested negative) while The Talk is on scheduled hiatus. Everyone please stay safe and healthy.”
In September Osbourne quarantined and appeared on her show via video link after she said one of her young granddaughters had tested positive.
Back in March their daughter Kelly Osbourne expressed concern for their health in the midst of the pandemic.
