United Kingdom Prime Minister Boris Johnson has confirmed that he has tested positive for COVID-19. This information comes from a tweet the Prime Minister himself posted, which can be viewed below.

In a video included in the tweet, Johnson confirmed he had a fever and a mild persistant cough. "At the advice of the Chief Medical Officer, I have taken a test that has come out positive. So I am working from home, I'm self-isolating, and that's entirely the right thing to do," he added in the video. Despite his illness, Johnson was quick to assure everyone that he will still be able to work, and was also quick to give thanks to the employees of the National Health Service, the police, social workers, and more.

If Johnson can no longer continue to serve his duties as Prime Minister, the New York Post is reporting that his stand-in will be Foreign Secretary Dominic Raab.

According to CBS News, Johnson is the first world leader to test positive for COVID-19. Shortly after Johnson posted his message on Twitter, the UK Secretary of State for Health and Social Care, Matt Hancock, also shared he has a similar diagnosis.

In Hancock's video, he mentioned the importance of working from home and maintaining social isolation measures to help slow down the spread of the Coronavirus. "The truth is that all of us can learn that working from home can be really, really effective," he said before ending his video.

According to the Evening Standard, there have been at least 11,658 confirmed cases of coronavirus across the UK, with at least 578 deaths.
