Are N95 masks actually effective against the virus? And can we up mass production on them?

If N95 masks are actually effective why don’t we just mandate all high risk folks to wear it since the mask will actually protect them. Also can we up the production of them to make sure all who want one can obtain one.

Pretty sure answer is yes & the ramped up production is going to hospitals

If everyone had an N95 mask, how would the OT bitch about people wearing cloth masks?
Posted on 7/12/20 at 11:47 am to STEVED00
Well no frickin way that mask can be worn in the field at this time of the year

Can we ramp it up even more?

They can't even keep up with the demand as it is.

Why would everyone need a N95 mask? The vast majority of the population is NOT high risk.

They have to be fit tested and the wearers have to be trained in how to wear them for them to be effective.
Yesterday at my voting place I saw one of the workers wearing a face shield, N95 mask, surgical gown and gloves. She had stepped outside for a snack and ate the donut with her gloves on, shield flipped up and mask pulled down over one of her chins.
That virus better just go on!!!!!!

Because a majority coming from the 3m plant in South Dakota is going towards the national stockpile. Trump is gonna make sure there is never a shortage again

Is that at Fort Knox?

Make hospital staff start sanitizing them and reusing them. Autoclave for the win.

We do reuse them. That’s the purpose of the surgical mask over the n95.

Look at the OT solving another crisis.

In order for an N-95 to be effective the user would have to have a fit test done to ensure they have the right size and proper fit.
Wearing an N-95 that doesn’t fit correctly would have little to no protection.
Also a proper fit would require all users to be clean shaven.
Remember the face mask (not n-95) isn’t to protect you, but to protect others.....at least that’s the argument they give instead of saying “we’re just trying to see Just how far we can go before people really start pushing back”

As a part of the high-risk population, I will gladly wear an N95 where warranted...and probably will in the future. I don’t right now, because want to leave them for the folks in the healthcare fields.
Trouble is, most people don’t know they have the underlying problems that make them “high risk.” I think almost everybody has one whether they know it or not.

Are N95 masks actually effective against the virus?
2017 trial about both viral and bacterial respiratory illnesses found n95 to be superior to surgical masks when looking at 3591 nurses in Beijing.
Surgical masks showed fewer infections than no mask, but it failed to reach statistical significance. If you click the full study (it's free on Wiley. I just linked the synopsis because I thought the "quick and dirty" would be generally preferred), you can scroll to Table 4 which looks at essentially all droplet-spread respiratory illnesses.
The findings?
Continuous N95 arm RR 0.26 (0.16-0.42) P<.001
Targeted N95 arm RR 0.43 (0.25-0.72) P=.001
Medical mask arm RR 0.65 (0.41-1.04) P=.074
What it means:
RR is relative risk vs control. The parantheseis gives the range that could be expected by the data above and the P is the decimal (convert to percentage by multiplying by 100) chance that this was all due to chance.
So for surgical masks, the study found nurses in sick patients were 65% as likely as someone not masking to get sick, test positive, or be able to culture the same pathogen the patient had. Analyzing that 65% closer says that you may be as good as 41% as likely vs nonmask but as bad as 104% (or slightly MORE likely). The chance that this is random chance (you roll a pair of dice looking for snake eyes and get 12 in a row. A statistical anomoly that very easily could happen but could never continue when carried out an infinite number of times...) is 7.4%.
Generally speaking, when a the number in parenthesis (confidence interval) crosses 1, it means that the available data are not statically significant to draw conclusions from. Similarly, the p value being >5% is generally higher than one would like. Doesn't mean you should just ignores the data, but it means that a better designed or larger study should be done.
So what does that mean for our n95 in the study?
Cuts the rate of transmission to about 1/4 nothing, and we are pretty sure that's not by chance (>99.9% sure)
Problem:
They're uncomfortable.
They can dig into your nose with extended use
If you aren't used to wearing them, breathing is fairly difficult. It's not a fat/skinny or in-shape vs unathletic type of thing. It's just an unusual situation and people take them off a lot.
Good news is that targeted n95 mask use was shown to be effective, but not as effective
The last point is that n95 masks must be fit tested or a general person's use of one isn't nearly as directly applicable.
And then lastly lastly, because of this and the propensity for it to spread via healthcare workers to patients, getting them into hospitals took priority to getting them to normal people and will continue to do so until there is a good supply so that the car wrecks who lay in a trauma ICU bed for a month don't get (and several other groups of similar long-stay patients) don't get COVID as well.

N95 are uncomfortable as frick. My face starts to itch after 10 minutes.
Posted on 7/12/20 at 1:58 pm to STEVED00
Nah, folks who actually need N95 for work-related purposes are supposed to give the only masks that protect them to the healthcare workers.
I guess my future lung issues/cancer isn't a concern.
