Boris Johnson’s chief medical officer Chris Whitty is self-isolating after experiencing coronavirus symptoms.

Professor Whitty said that he would be staying at home for the next seven days in a statement on Twitter, posted just hours after the prime minister confirmed that he had also tested positive for the COVID-19 disease.

After experiencing symptoms compatible with COVID-19 last night, in line with the guidance, I will be self-isolating at home for the next seven days, said the professor.

I will be continuing to advise the government on the medical response to coronavirus, supported by my deputies.

Professor Whitty has been a fixture of the government’s daily news briefings on the UK response to the disease, alongside the chief scientific adviser Sir Patrick Vallance.

He is the third major figure leading the country’s battle against coronavirus to have gone into self-isolation on Friday, following the prime minister and Health Secretary Matt Hancock.

Mr Hancock revealed shortly after Mr Johnson that he had tested positive after experiencing mild symptoms.
