It doesn’t really matter if masks are useful or not. People have been breathing on each other for millennia and the idea that we should all face mask to avoid exposing other people to our germs would have been regarded, until a few months ago, as preposterous by most. The idea is still preposterous, and the only non-controversial science about masks is that rebreathing one’s own respiratory wastes is unhealthy. From Jon Miltimore at fee.org:
The top medical experts in the world can’t decide if masks are helpful in reducing the spread of COVID-19 or just make things worse.
enmark boasts one of the lowest COVID-19 death rates in the world. As of August 4, the Danes have suffered 616 COVID-19 deaths, according to figures from Johns Hopkins University.
That’s less than one-third of the number of Danes who die from pneumonia or influenza in a given year.
Despite this success, Danish leaders recently found themselves on the defensive. The reason is that Danes aren’t wearing face masks, and local authorities for the most part aren’t even recommending them.
This prompted Berlingske, the country’s oldest newspaper, to complain that Danes had positioned themselves “to the right of Trump.”
“The whole world is wearing face masks, even Donald Trump,” Berlingske pointed out.
This apparently did not sit well with Danish health officials. They responded by noting there is little conclusive evidence that face masks are an effective way to limit the spread of respiratory viruses.
“All these countries recommending face masks haven’t made their decisions based on new studies,” said Henning Bundgaard, chief physician at Denmark’s Rigshospitale, according to Bloomberg News. (Denmark has since updated its guidelines to encourage, but not require, the use of masks on public transit where social distancing may not be possible.)
Denmark is not alone.
Despite a global stampede of mask-wearing, data show that 80-90 percent of people in Finland and Holland say they “never” wear masks when they go out, a sharp contrast to the 80-90 percent of people in Spain and Italy who say they “always” wear masks when they go out.
Dutch public health officials recently explained why they’re not recommending masks.
“From a medical point of view, there is no evidence of a medical effect of wearing face masks, so we decided not to impose a national obligation,” said Medical Care Minister Tamara van Ark.
Others, echoing statements similar to the US Surgeon General from early March, said masks could make individuals sicker and exacerbate the spread of the virus.
“Face masks in public places are not necessary, based on all the current evidence,” said Coen Berends, spokesman for the National Institute for Public Health and the Environment. “There is no benefit and there may even be negative impact.”
In Sweden, where COVID-19 deaths have slowed to a crawl, public health officials say they see “no point” in requiring individuals to wear masks.
