The Canadian Prime Minister Justin Trudeau is self-isolating himself, after his wife started to show flu-like symptoms.
Sophie Grégoire Trudeau recently returned from an event in Britain.
She began exhibiting mild, flu-like symptoms - including a low fever - on Wednesday and is being tested for the coronavirus.
She is self-isolating at home waiting for the test results.
A statement from Mr Trudeau's office says he is to work from home "out of an abundance of caution".
He will continue to speak with ministers and take part in virtual meetings, it adds.
"The prime minister will spend the day in briefings, phone calls, and virtual meetings from home, including speaking with other world leaders and joining the special COVID-19 cabinet committee discussion".
Canada has reported 103 cases of the COVID-19 virus.
The country has also announced several measures to deal with the outbreak.
This includes support for workers in quarantine or who have been directed to self-isolate, and enhancements to a work-sharing program to help support employers and workers.
Meanwhile 10 people have died from coronavirus in the UK as the country experienced its largest day-on-day increase of cases.
The number of coronavirus cases in Britain has reached 590 - up 134 in the last 24 hours.
