Popular blue surgical face masks do NOT stop people from getting or giving the Chinese Flu

We’ve always known that, but The Daily Mail has escaped from behind the Twitter bar to tell us again.

But masking has never been about stopping disease; it’s theatre, a demand for an outward display of obeisance by the little people. And in that regard, it’s done very well.

Yarusevych and team said that many people wear masks that don't fit their faces properly, unlike the N95, which straps itself tightly around the wearer. 

This causes aerosol droplets to escape through multiple openings between a person's face and the cloth mask, which could spread COVID-19 in populous areas. 

The N95 was conversely able to filter over 50% of aerosol droplets while the other half is dispersed above the wearer's head. 

Yarusevych team added that ventilation tests revealed even modest ventilation rates provide about the same level of protection as the highest quality masks.
