Canadian Prime Minister Justin Trudeau is quarantining himself as his wife awaits test results to see if she has the coronavirus.

The Canadian first lady, Sophie Gregoire Trudeau, “began exhibiting mild flu-like symptoms including a low fever” after returning from “a speaking engagement” in London, according to a statement released by the prime minister’s office on Thursday. She is being tested for the COVID-19 virus and is self-quarantining and working from home until she gets the results.
