Cloth face masks offer little to know protection against COVID-19! As the saying goes, something is better than nothing. While it's true cloth face masks do provide a barrier, they do not filter particles which attach to the fibers of the cloth material.
As a face mask expert, my advise is if you have to wear a cloth mask then avoid large crowds. It's best not to wear cloth when in groups because there are so many particles flying through the air they're going to stick to the outside of the cloth.
Give it a few weeks and the CDC will catch up to the reality that cloth face masks should be a last resort. In the meantime, don't wait for the CDC to issue guidelines about protecting yourself from COVID-19.
