The wording of that is rather suggestive. Mostly, I've been just posting other information as the evidence for this really isn't as settled as you seem to indicate. As I stated earlier, we had the chance to do better studies that may have settled this question. My opinion is that it might help, doesn't hurt anything, and isn't really a burden on anyone. The side effects are minimal. Previous studies suggest cloth masks have some small efficacy in reducing the spread from sick people to healthy ones with other airborne viruses, which is different from the CDC recommendation you posted. No, most of the day, I'm the only person in my work space. I have them available when I go to those places which request or require them. I don't find them onerous, but it seems some people posting in this thread do apparently find them extremely uncomfortable.
