I posted this in a reply in the urban section, but it probably belongs here. Everyone should read this link concerning the effectiveness of masks and respirators (all types).

This is not a you should or should not discussion for COVID-19. This is data on masks and mask substitutes and their efficiency in filtration.

One of the things we always talk about is having a bandanna for temporary respiratory protection in the event of an earthquake or other building collapse scenario. If asbestos is part of the equation (older buildings) it is notoriously hard to filter out of the air.

Good share, thank you!

They didn't mention wool masks.

Or pantyhose

"Even the surgical mask performed better with stockings in their study: Testing showed that it went from blocking out 75% of small particles to 90% with the addition of a pantyhose overlayer. An N95 respirator, by comparison, is designed to block out at least 95% of small particles when worn properly."

Interesting, was wondering if buffs would be of use as already have a couple.

Seems might over a surgical mask.

When necessary I wear a neck gator and leave my masks (surgical or washable/reusable) at home. The neck gator (aka buff) fills the need of a face covering. Since it appears that 21% of NY'rs have tested positive for COVID-19 antibodies, this thing is apparently not as deadly as initially reported.

I've been using a section cut from an Oreck vacuum cleaner bag pinned inside a doubled-over shemagh scarf. At the top of the fold of the scarf there's a 4-inck piece of 10-gauge wire pinned in place to shape the scarf where it crosses my nose.

Is that according to the "Tyler Durden" of the prestegious ZeroHedge?
Appears to be so ... uhoh



As of this hour
Total Confirmed 3,344,435
Total Deaths 238,788
238788/3344435 = 7.1398607 /100

1,103,781 US (65,068)
65068/1103781 = 5.89501 /100

In January the tip of the disease burden pyramid said ~2%
In April tip of US pyramid said ~4%

I'd leave the number interpretation to CDC/... not random "journalist"/blogger

The odd thing is that in some states the death rate has been nearly 10%. It's hard to figure why it's so much deadlier in some places than others.

Some coroners have stated that any decedent that tests positive for COVID-19 and did not die of trauma will be counted as a COVID-19 death.

Other places are doing a far better job of granular reporting. My friend the data scientist says that Georgia in particular is doing a very good job of that.
