British Prime Minister Boris Johnson Tests Postive

British Prime Minister Boris Johnson has tested positive for coronavirus and has been forced into isolation during the worsening emergency in the United Kingdom.

A Downing Street spokesperson said that the Prime Minister was tested after experiencing symptoms on Thursday "on the personal advice of England's Chief Medical Officer, Professor Chris Whitty."

"The test was carried out in No. 10 by NHS staff and the result of the test was positive," the spokesperson said.

In a video posted to Twitter, Johnson, aged 55, said he had developed mild symptoms and was tested inside by Downing Street by National Health Service staff on the advice on the country's chief medical officer.

He vowed to continue leading Britain's response to the pandemic via teleconferencing, however the diagnosis will raise questions about the Prime Minister's contact over recent weeks with other key officials and cabinet ministers.

The confirmation comes just over a week after a top government adviser on the virus, Neil Ferguson, said he believed he had been infected and warned: "There is a lot of Covid-19 in Westminster."

Ferguson had met with the Prime Minister, as well as Whitty, and Chief Scientific Adviser Patrick Vallance. It was not clear, however, where Johnson may have contracted the virus.

The infection also raises concerns over Johnson's fiancee, Carrie Symonds, who is pregnant.
