Trudeau, wife in self-isolation

On Thursday evening, the Prime Minister's Office said Sophie Grégoire Trudeau had tested positive for the virus which causes COVID-19. It said she and Justin Trudeau will remain in isolation.

"She is feeling well, is taking all the recommended precautions and her symptoms remain mild," the PMO said in a statement.

It said the prime minister will not be tested for the virus at this time because he does not have any symptoms.

I have some personal news to share today. Sophie recently returned from a speaking event in the UK, and last night she was experiencing mild flu-like symptoms. She‘s feeling better, but following the advice of our doctor she is self-isolating as we wait on COVID-19 test results. —@JustinTrudeau

Also Thursday, Deputy Prime Minister Chrystia Freeland told CBC News Network that the United States did not notify Canada before announcing travel restrictions on Europe.

U.S. President Donald Trump announced Wednesday evening that all European travel would be cut off, but U.S. officials later clarified that restrictions would apply only to most foreign citizens who have been in Europe's passport-free travel zone at any point for 14 days prior to their arrival to the U.S.

Trump said Thursday he had excluded the United Kingdom from the curbs because it was doing a good job in tackling the coronavirus. He said he was unable to consult with European officials before implementing the restrictions because he had to move quickly.

"I don't want people dying; that's what I'm all about," said Trump.

"I made a very tough decision last night, and a very tough decision a long time ago," he said, referring to an earlier restriction on travel to and from China.

Federal Health Minister Patty Hajdu said Wednesday that the evidence is still not firm, but that the infection rate could be anywhere from 30 to 70 per cent.

For most, the coronavirus causes only mild or moderate symptoms, such as fever and cough. For seniors and those with underlying health issues, it can cause more severe illness, including pneumonia. But the vast majority recover: people with mild illness recover in about two weeks, while more severe illness may take three to six weeks, World Health Organization (WHO) says.

Here's how the Canadian government is responding

Canada's chief public health officer is urging people to take precautions and make efforts to slow the spread of coronavirus, which WHO has described as a pandemic after it spread to at least 114 countries.

Dr. Theresa Tam urged people to take control measures, including proper hand hygiene, staying home if sick and social distancing.

The Public Health Agency of Canada (PHAC), which has been assessing the risks associated with the outbreak, says the risk from the coronavirus to the general population in Canada is low, but it notes the situation could change quickly. PHAC says people who are over 65, have underlying medical issues or a compromised immune system face "an increased risk of more severe outcomes."

Tam's suggestions came after Trudeau announced a $1-billion fund to help fight COVID-19, with funding for a range of initiatives, including provincial health systems, procurement of essential equipment and protective gear, as well as research into the coronavirus.

What's happening in the rest of the world

The European Union lashed out at Trump's "unilateral" travel decision, saying that the illness does not respect borders.

"The European Union disapproves of the fact that the U.S. decision to impose a travel ban was taken unilaterally and without consultation," EU Council President Charles Michel and Commission President Ursula von der Leyen said in a joint statement.

"The coronavirus is a global crisis, not limited to any continent, and it requires co-operation rather than unilateral action."

They rejected Trump's suggestion that Europe is not doing enough to combat COVID-19, saying the 27-nation bloc "is taking strong action to limit the spread of the virus."

Anthony Fauci, who heads the National Institute of Allergy and Infectious Diseases, acknowledged that the U.S. was lagging other countries in testing for the virus to learn how widespread it really is.

"The system is not really geared to what we need, right now.… That is a failing. Let's admit it," Fauci said.

But Fauci and Centers for Disease Control and Prevention Director Robert Redfield both appeared to support curtailing travel from Europe, stating that 70 per cent of new infections are coming from that continent.

"Europe is the new China" in terms of the epicentre of the pandemic, Redfield said.
