London (CNN) British Prime Minister Boris Johnson is "able to do short walks" after he was moved out of intensive care at a London hospital where he has been receiving treatment for the coronavirus, a spokesman said Friday.

"The Prime Minister has been able to do short walks, between periods of rest, as part of the care he is receiving to aid his recovery," the spokeman for 10 Downing Street said.

"He has spoken to his doctors and thanks the whole clinical team for the incredible care he has received.

"His thoughts are with those affected by this terrible disease."

Workers have been erecting a fence in recent days to block the view of the ambulance entrance at St Thomas' Hospital in London, where British Prime Minister Boris Johnson is being treated for coronavirus.

Johnson, 55, is "just beginning his recovery " and "continues to be in very good spirits," his official spokesman said earlier Friday.
