“On the advice of his doctor, the Prime Minister has tonight been admitted to hospital for tests,” the Prime Minister’s Office said in a statement.

The decision to go to the hospital was described as a “precautionary step.”

“Prime Minister continues to have persistent symptoms of coronavirus 10 days after testing positive for the virus,” Downing Street explained in a statement, Sunday. “The Prime Minister thanks NHS staff for all of their incredible hard work and urges the public to continue to follow the Government’s advice to stay at home, protect the NHS and save lives.”

CNN’s Medical Analyst Dr. Kent Sepkowitz says that the tests Johnson will receive could reveal “several more variables of lung function and might indicate whether he is just fatigued and spent, or actually in some danger.” 

In the time since his diagnosis, Johnson has worked from home and lived in accordance with social distancing guidelines.

On Friday, Johnson released an update video on Twitter saying he was still experiencing symptoms: “I still have a temperature. So in accordance with government advice I must continue my self-isolation until that symptom itself goes.”

There are now more than 1.2 million cases of coronavirus around the world. Over 68,000 have died.
