British Prime Minister Boris Johnson's fiancée, Carrie Simmonds praised the medical team that helped him bypass Covid-19, adding that there were "very difficult" times last week.

"I cannot thank our National Health Authority enough. The staff at St. Thomas Hospital were incredibly wonderful. I am not and I will not be able to return your favors," said 32-year-old Simmonds, who also suffered from symptoms of corona and is also pregnant. And I will never stop thanking you. "

"There were really very difficult times during the past week. My heartfelt feelings are with all those in similar circumstances who are anxious for their loved ones."

Johnson spent three nights in the intensive care room while he was staying at St. Thomas Hospital. His office said on Sunday that he had left the hospital and would continue to recover at the Prime Minister's official rural residence.

On leaving hospital, Johnson said - in a five-minute video on Twitter from government headquarters on 10 Downing Street - "I left the hospital today a week after the National Health Authority saved my life, without a doubt."

Johnson thanked the nurses who took care of him, giving their names.

"The reason why my body finally started getting enough oxygen is every second night that they watch, think, take care of me and make the interventions that I needed," he said.

British Health Secretary Matt Hancock said Sunday that Johnson is currently resting at his official residence in Checkers, and there is no advice as to how long this rest will take.

Johnson, 55, was transferred to St. Thomas Hospital in central London on April 5 for suffering from persistent symptoms of the disease caused by the emerging coronavirus. He entered intensive care on April 6 and stayed there until the ninth of the month.
