This is the text (if you need help).
The U.K. Prime Minister, Boris Johnson, thanked the National Health Service for saving his life. Mr Johnson, 55, tested positive for COVID-19 and self-isolated in London. He continued to lead the UK's response to the coronavirus pandemic. However, his condition worsened. He went to hospital for tests and was moved to an intensive care unit. This was a "precautionary move". He remained conscious and could breathe without help from a ventilator.
Mr Johnson said the care he received from nurses was "exemplary". He said: "I can't thank them enough. I owe them my life." He is now recovering and making "very good progress". He is doing puzzles and watching films. His biographer said: "Boris...believed he was strong enough to keep going regardless of any symptoms from which he might be suffering. His strong [tendency] was to overwork, not to put his feet up."
