So it was no surprise that the release of the 2023 Cochrane Review , which determined that masking is ineffective against the spread of respiratory illnesses such as influenza or COVID-19, was greeted by a chorus of crickets in the media.
The review analyzed the findings of 78 other studies that involved more than half a million people from across the globe and found that wearing a medical or surgical mask “probably makes little or no difference” in reducing the spread of respiratory viruses.
It makes little or no difference in anything, even infections in surgical patients.
Masks literally do less than nothing.
