Elba made the announcement on his Twitter page and says he feels no symptoms and has been isolated since his his diagnosis.
“I feel OK, I have no symptoms so far but have been isolated since I found out about my possible exposure to the virus,” he tweeted. “Stay home people and be pragmatic. I will keep you updated on how I’m doing – No panic.”
He also posted a video with him and his wife, Sabrina Dhowre Elba. He said she had not been tested yet but was not showing any symptoms.
He said he found out Friday that someone he had been in contact with had tested positive. He has self-quarantined since and got his test results back Monday.
In the video he encouraged everyone to practice social distancing, wash their hands often and follow other recommendations for lowering the risk of exposure.
“Transparency is probably the best thing for this right now,” he said. “If you’re feeling ill, or you feel like you should be tested or have been exposed, you should do something about it, alright? It’s really important.”
