Will you do one on surgical masks?

So this is what you had been hinting at on an earlier Zdogg podcast! "Stay tuned..." I remember hearing! @ZDoggMD

@GovPritzker @JBPritzker @chicagosmayor @LoriLightfoot @DrArwady You've said that as the data changes your opinion can change. Well, this paper summarizes that the data on cloth masks is extremely weak. Will you consider making them a personal choice?

I’ve checked a few of the studies reviewed. Most are in households. Face masks, which *reduce* and *slow down* air flow without *stopping* it, are least effective with long exposure times, such as households. That doesn’t mean that they’re ineffective eg at the supermarket

Why publish through CATO? Is there no medical or public health organization or journal that would publish this resource?

Very thorough! May be worth adding for the Theodore Roosevelt study: the sailors weren’t actually wearing cloth or surgical masks during the time period being studied. mobile.twitter.com/EileenCho…

I haven't reviewed the whole of the evidence for cloth masks since then. They might help. But let me take a moment to refute one terrible but widely-cited paper claiming masks worked on the USS Theodore Roosevelt. I can do it with one video. invidious.fdn.fr/watch?v=mPCx4xP6…

Combination of seasonality and the virus going through the most susceptible population first? 🤷🏼‍♂️
