After downplaying the effectiveness of non-medical face masks, both the chief public health officer and federal health minister now say they would wear them in cases where physical distancing isn't possible in public.
Theresa Tam, the country's top doctor, said Tuesday that while the scientific research "is not quite there" yet on the effectiveness of non-medical masks in stopping the spread of COVID-19, she wouldn't hesitate to use a mask when grocery shopping or riding transit.
"That's one option," she said of wearing a mask. "It is an added layer of prevention and protecting the spreading to others."
Tam has suggested a t-shirt or bed sheet could be fashioned into a homemade mask. But medical-grade masks should be strictly reserved for health care professionals, given the ongoing shortages, Tam said.
Health Minister Patty Hajdu said she hasn't had to wear a mask to this point because she's been able to maintain that two metre distance between herself and others — but she would wear one if it meant protecting others in confined spaces.
谭医生，卫生部长也要戴口罩了。不知道谭医生，戴上口罩会不会抓脸，捅眼，摸嘴？
口要有效需要证据，口罩有害不需要证据。双标的典型例子啊。
