Boris Johnson forced to continue self-isolation with high temperature after testing positive for coronavirus

Boris Johnson has been forced to remain in self-isolation with a temperature after testing positive for coronavirus last week.

The Prime Minister posted an update on his condition on Twitter, saying that he continues to suffer from one of the symptoms of Covid-19.

He said: “In my own case, although I’m feeling better and I’ve done my seven days of isolation, alas I still have one of the symptoms, a minor symptom, I still have a temperature.

“And so in accordance with Government advice I must continue my self-isolation until that symptom itself goes.​

“But we’re working clearly the whole time on our programme to defeat the virus. You’ll have seen the big announcement yesterday about 100,000 tests a day by the end of the month.”

Mr Johnson urged Brits to abide by lockdown rules this weekend, despite the warm weather forecasts.

He said: "I reckon a lot of people are going to think that this is all going on for a long time and they’d rather get out there - particularly if they’ve got kids in the household and everybody might be going a bit stir crazy, and there may be a temptation to get out there, hang out and start to break the regulations."

The Prime Minister asked Brits to stick to the guidelines to help lower the burden on the NHS.

He added: "This country has made a huge effort, a huge sacrifice, done absolutely brilliantly well in delaying the spread of the virus.

"Let’s stick with it now. Remember that incredible clapping again last night for our fantastic NHS. Let’s do it to protect them and save lives."

Mr Johnson's words follow warnings by both Public Health England and the Met Office that the public shouldn't break the lockdown for the warm weather.

Their advice comes after Health Secretary Matt Hancock said on Friday that the peak of UK coronavirus deaths may come sooner than expected and suggested the lockdown may have to be prolonged.

Another large increase in UK infections and fatalities is anticipated this afternoon on top of yesterday’s official tally of 33,718 confirmed cases, including 9,291 in London alone, and 2,921 deaths.

The Government said on Thursday that it is considering handing out "immunity passports" to those who have already had the virus - to allow people to "get back, as much as possible, to normal life” amid a nationwide lockdown.

But experts have criticised the potential move as "dangerous".

Eleanor Riley, Professor of Immunology and Infectious Disease at the University of Edinburgh, said: "We don't know yet whether somebody who has had this virus is immune.

"They have antibodies, they've clearly been exposed, yet will those antibodies protect them against reinfection? I'm not sure that we know that."
