For studies that focus on mask effectiveness, please see my original comment’s study and the three studies I linked here: https://www.freerepublic.com/focus/news/3886112/posts?page=60#60
As for Arkansas, your argument is not with masks; it’s with mask mandates. A mandate doesn’t make the problem disappear. If it did, we wouldn’t see any shootings in “gun-free school zones”. A mandate doesn’t reduce the risk of viral transmission. Most or all of the population wearing a properly made, properly worn mask the entire time they’re in a situation where it makes sense to do so (indoors in a public place, outside doesn’t matter since it doesn’t spread much at all there) reduces the risk of transmission.
It has been 3 months. They don’t work here.
I don’t want a study. I want real world results not bullshit studies that require a perfect setting.
