Going to post the scientific paper that backs that info up? Or is it a case of “my mate Dave down the pub told meâ€
No scientific paper. I'm referring to news reports about WHO advice from back in march when we were asking why we weren't being told to wear masks from the start.
I said last I heard, not last scientific paper I read but it feels like you're really saying you don't agree with me when all I'm saying is I'm surprised more people haven't raised the issue of the effectiveness of masks.
