Despite the vast amounts of research that has gone into the effectiveness of wearing a mask for reducing the spread of disease — that is, after all, why surgeons and dentists, among many others, have worn them for hours on end for decades — the efforts of the anti-mask movement in America have swayed far too many people.
And indeed, there has been some confusion about whether or not people should be wearing masks, and if so, in what situations they're necessary. Much of that stems from efforts early on in the COVID-19 pandemic to conserve PPE for use by frontline healthcare workers.
But the science is clearly on the side of wearing masks and who better to break down the reasons why than Bill Nye The Science Guy?
