Ontario’s Chief Medical Officer of Health Dr. David Williams said there were 19 people under investigation for coronavirus in the province at the moment.

What that means: Dr. Williams said that for a person to be "under investigation," they must have both signs or symptoms of a respiratory condition and a travel history that is "of importance, which is to Wuhan or around the district of the Hubei province.”

He added that people being investigated for coronavirus will undergo a battery of health tests to rule out other causes.
