Nearly all who now say cloth masks are effective..have no experience in this area. Dr. Lisa Brosseau has spent her career on this..worth listening to this interview. Her concern is that public health reversal, gives people false sense of security https://publichealth.uic.edu/news-stories/mask-orders-and-the-science-of-homemade-masks/ …

All good with wanting more evidence on masks—different types, source-control versus PPE—but I find it baffling that "false sense of security" which is *utterly evidence free and if anything has evidence against* is touted by experts who allegedly have high standards for evidence!

My main thing: can wearing a mask HURT you? No. Keep washing your hands, observing social distancing, etc. Masks may not have enough evidence of benefit, but the downsides of wearing them are few.

I have masks. happy to wear them. My concern is people (especially politicians), over stating the benefit (if any, especially when people re-wear disposable masks) which could be a public health risk. but let me defer to Dr. Mike Osterholm https://www.cidrap.umn.edu/covid-19/podcasts-webinars/special-ep-masks …

This expert, too, allegedly has high standards for evidence and wants to convey uncertainty (I'm all for that when appropriate!) but is making claims about false sense of security that are both evidence-free and contradicted by actual evidence! This is such a baffling pattern!
