British Prime Minister Boris Johnson thanked the national healthcare system for saving his life after he was hospitalized for a week with the coronavirus.

"It is hard to find the words to express my debt to the NHS for saving my life," Johnson said.

"The efforts of millions of people across this country to stay home are worth it. Together we will overcome this challenge, as we have overcome so many challenges in the past."

Johnson was released from St. Thomas' hospital, where he had been admitted 10 days after being diagnosed with the coronavirus.

On Wednesday, his condition began to improve, and he was able to communicate with doctors.

Johnson spent three nights in intensive care before returning to a regular ward on Thursday.

Downing Street said the PM would continue the recovery process at his country residence, Chequers.
