Canada's chief medical officer of health says she understands why some provinces have shortened the isolation period for COVID-19 infection.
Over the holidays, Ontario and Quebec cut the length of isolation periods for infected people by half, to just five days.
Dr. Theresa Tam says the provinces are trying to pull off a balancing act for the economy.
Tam's deputy, Dr. Howard Njoo, says the federal public health agency is in discussions with provinces and the Centers for Disease Control in the United States about the ideal isolation period.
