British Prime Minister Boris Johnson was admitted to a hospital Sunday for tests, his office said, because he is still suffering symptoms, 10 days after he was diagnosed with COVID-19. The prime minister’s Downing St. office said it was a “precautionary step” and Johnson remains in charge of the government. Johnson, 55, has been quarantined in his Downing St. residence since being diagnosed with COVID-19 on March 26 — the first known head of government to fall ill with the virus.
