Supposedly if it has a valve (which some N95’s have) it only blocks particles from being inhaled, but not from coming out.
And isn't the protection offered by masks mainly about protecting other from droplets or aerosols being exhaled?
RWJ Hospital in New Brunswick, NJ has a sign disallowing masks with vents for visitors. No medical workers that I saw there had masks with vents either.
A new study compares 14 different types of masks for preventing droplet transmission, valved N95 masks are not nearly as bad as many of the masks that people are allowed to use. https://advances.sciencemag.org/content/early/2020/08/07/sciadv.abd3083.full

So... the CDC changed the current best estimate of the IFR to .65% (which is much more in line with reality) without telling anyone. I’m waiting to hear some breathless news reports in another couple of weeks about this “breaking news”.(They also assume that asymptomatic people are 75% as infectious as symptomatic people, and 50% of transmission occurs before symptoms appear).https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios.html#box
From what I'm seeing in FL, it seems the fatality rate is stabilized at roughly 1.5%. Given the amount of testing, I think the IFR should be ticking up a bit closer to 1%.
How do you get those numbers? If you just divide cases by deaths 536k/8200 = .65% which is right in line with what the cdc said. And when the cases count was higher per day the deaths were still low.
