Britain's Prime Minister Boris Johnson left the St. Thomas' Hospital in London on Sunday after undergoing rigorous treatment as he had tested positive for the coronavirus a few days back. In a video posted on his Twitter page, Mr. Johnson thanked two nurses, Jenny from New Zealand and Luis from Portugal, for taking good care of him during the ordeal while also extending his gratitude towards the National Health Service (NHS) staff who, "kept putting themselves in harm's way, kept risking this deadly virus". He added, "It is thanks to that courage, that devotion, that duty and that love that our NHS has been unbeatable,".

It is hard to find the words to express my debt to the NHS for saving my life.

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. #StayHomeSaveLives pic.twitter.com/HK7Ch8BMB5

Prime Minister Boris Johnson was admitted in the St. Thomas' Hospital in London on April 5 after showing COVID-19 symptoms after which he was moved the following day to the intensive care unit where he remained until April 9. Prior to be taken to the hospital, Mr. Johnson, 55, had been undergoing treatment by self isolating himself for nearly 10 days after showing mild symptoms for COVID-19 disease.

The Prime Minster's office, 10, Downing Street, issued a statement saying Mr. Johnson would continue his treatment and recovery at his country residence, Chequers, as the total death toll in the UK from the coronavirus has gone up to 10,612 after 737 people succumbed to the disease on Saturday. The statement is as follows: "On the advice of his medical team, the PM will not be immediately returning to work. He wishes to thank everybody at St Thomas' for the brilliant care he has received. "All of his thoughts are with those affected by this illness."

When queried how long it would be before Boris Johnson returned to work, Health Secretary Matt Hancock said, "That will be a clinical decision for his doctors to take with him. The government is operating perfectly efficiently within the strategy he set out." Foreign Secretary Dominic Raab, who has taken over the Prime Minister's duties, is reportedly expecting Mr. Johnson to undergo recovery for as long as a month.
