OTTAWA—Wearing a simple cloth mask is a way for someone who might have COVID-19 without realizing it to avoid spreading the illness to others, Canada’s top public−health doctor said Monday.

Dr. Theresa Tam said the new advice, a shift from previous instructions, flows from increasing evidence that people with the CCP (Chinese Communist Party) virus, commonly known as novel coronavirus, can spread it without knowing they’re sick.
