Study finds mask wearing likely makes 'little or no difference' regarding flu transmission.

This verdict ought to be the death knell for mask mandates, but that would require the Centers for Disease Control (CDC) and the rest of the public-health establishment to forsake “the science”—and unfortunately, these leaders and their acolytes in the media seem as determined as ever to ignore actual science. Before the pandemic, clinical trials repeatedly showed little or no benefit from wearing masks in preventing the spread of respiratory illnesses like flu and colds. That was why, in their pre-2020 plans for dealing with a viral pandemic, the World Health Organization, the CDC, and other national public-health agencies did not recommend masking the public. But once Covid-19 arrived, magical thinking prevailed. Officials ignored the previous findings and plans, instead touting crude and easily debunked studies purporting to show that masks worked.
