The latest figures show that the death rate of those admitted to intensive care in the UK now exceeds 50%.
Dr Simon Clarke, a microbiologist, told Sky News: "I'll say this to you, the NHS, particularly at this moment, doesn't give up intensive care beds just for people to be looked over - it doesn't work like that, even for prime ministers.
"He would not be in intensive care unless he needed to be in intensive care, especially not at this time, and I think it's probably about time that the press people in Number 10 started levelling with us about what his condition really is."
呢個病真係古怪。最早瀨嘢嗰個衛生部parliamentary under secretary Nadine Dorries同佢老母已經冇事，佢仲要話佢老母
"Unlike with my situation, we know exactly where she caught it from and the irony is, despite her having had major surgery to replace the valves in her heart damaged by childhood illness, despite her pacemaker and breathlessness, her lifetime of smoking, hard work in her early years and poor diet, she had much milder symptoms than me."
