According to study had minimal effectiveness in hospitals and homes (long term care homes?)
BUT
NOT EFFECTIVE AT ALL in broader community
They found that surgical or medical procedural masks, which are often blue with three pleats, offer at least “moderate protection” against contracting an infection in a home setting when a sick person and a healthy person are both wearing one. In those situations, the likelihood of contracting an infection is reduced by 18 to 31 per cent, the researchers said.
The researchers were unable to say whether the wearing of face coverings like artisanal masks or other cloth barriers in front of the mouth and nose were effective. They did notice that medical masks seemed to be more effective at preventing infection than cloth barriers in a medical setting, but they would not say whether this would probably extend to the community, citing insufficient research.
Even goes so far as to acknowledge that anti-maskers will "probably" use their findings. I esp love the "other countries seem to think" despite what the SCIENCE in CANADA has shown
“Absolutely, the anti-maskers are going to use it. But you will understand that we must not make science say what it cannot say either,” he said. “But I strongly recommend that you wear it, because in the current context, some countries seem to have shown a decrease in incidence with it.”
