The Health Secretary Matt Hancock has revealed he has coronavirus. 

His announcement comes just hours after the prime minister Boris Johnson announced he had tested positive or the disease. 

Addressing the public in a tweet, the minister wrote: "Following medical advice, I was advised to test for #Coronavirus.

"I‘ve tested positive. Thankfully my symptoms are mild and I’m working from home & self-isolating.

"Vital we follow the advice to protect our NHS & save lives #StayHomeSaveLives."

Mr Johnson is currently self-isolating at Downing Street after coming down with a mild fever.

A study by Oxford University published earlier this week found that as many as half the population could have coronavirus.

However the findings were rubbished by rival universities.

“It’s a little concerning that they’ve taken it straight to the media,” Tim Colbourn, an epidemiologist at University College London’s Institute for Global Health, told online publication Wired. “It has not been properly sense-checked against any data.”
