Wearing a cloth mask or bandana when unable to maintain distance is better than nothing, but not much. Take a peek at a British mEdical Journal study that shows that a cloth mask filters out only 3% of any particles in the air.

Cloth masks offer very little protection against coronavirus
Do your homework. Vet your sources and double/triple check your info. Don’t take advice from those who are pushing a political agenda, or got their medical degrees from University of Facebook or Twitter State. Don’t be lulled into a false sense of security just because you or someone else has a bandana on their face.
That said, yeah, I’ll wear one to the grocery store, or if I ever get on the el or bus again where maintaining distance doesn’t always happen.
Being outdoors is another story. There is ample opportunity to provide a wide berth to others. If I go out for a hike, I’m not going to wear a mask. No amount of cancel culture tactics will change that. If anyone’s immune system is so compromised, or they are so paranoid, or so afraid, then, with all due respect, they should be the ones who keep their asses in the house.
