British Prime Minister Boris Johnson's is now in an intensive care unit ... a strong sign his coronavirus symptoms are worsening.
Johnson was admitted to St. Thomas' Hospital Sunday night ... according to a government spokesperson, who added "the Prime Minister has worsened and, on the advice of his medical team, he has been moved to the Intensive Care Unit at the hospital."
It's not a great sign, however, the spokesperson says Johnson is conscious and doesn't need a ventilator, yet. They say he's been moved to ICU, just in case he needs one in the near future.
The 55-year-old UK leader has nominated Foreign Secretary Dominic Raab to run the country.
Johnson announced 10 days ago he'd tested positive for COVID-19. It appears he underestimated the seriousness of the virus early on, because he shook hands with patients weeks before his own diagnosis.
As you know, Prince Charles also tested positive, but has since said he's "on the other side" of the illness. Here's hoping Boris finds his way there too.
