What’s the absolute risk reduction, given the current prevalence of disease?

DrAsh- Somewhere between 10-70% depending on quality. The WHO recommends cloth mask with 3 layers and this should provide protection towards the higher end of this range.

What makes you the expert DocAsh? If I were you I’d show some respect for a person with authority and clearly more knowledge on edipemiology than you.

cloth masks can’t provide medical grade mask protection and medical masks are in short supply globally. Not surprising WHO want to offer community some protection rather than none but you personally dont have to choose.
