Cloth masks are NOT enough to stop the spread of Covid-19 without social distancing because they let in enough droplets to infect someone standing less than six feet away, study finds
Five types of masks were examined: an N95 mask, s surgical mask, a cloth mask, a two-layer cloth mask and a wet two-later cloth mask
Each mask was tested again a machine that uses an air generator to blow tiny liquid droplets, like those that would escape from a nose or a mouth
The N95 blocked the most at 100% of droplets and the regular cloth mask blocked the least at 96.4% of droplets
