Face mask effectiveness: What we know now 

Right!?!? All these people talking about "correct fitting N-95 masks" definitely aren't the majority.

Masks dnw anyway.

if you watched the entire video she did talk about cloth masks as well

@@destinationlimbo378 🐑

yeah, I have a PhD in organic chemistry. Not totally qualified to talk about this for sure. But have some understanding. We work with infectious disease processes. She states 80 percent efficacy which is probably also false. Surgical masks were designed to block large particulates such as Sputum from contacting a open surface. Were never meant to protect the surgical staff from illness. Other than splatter or what not. Sure there may have been some benefit in dispersing viral load but was probably very minimal.

I work as a medical assistant and I never got sick in patient facing areas when I had a mask. I did sit next to my sick co-worker at lunch however...

Ok, well what was even the point of surgical masks if we knew they were worse. What kind of public health policy would not specify the difference explicitly.

They never promised 100% coverage....

*an N95

same experience here. 3m aura n95s are my favorite tool discovery in this ONGOING pandemic followed by my diy corsi rosenthal air filter. i never remove my n95 in a public space for a ‘short break’ and never in an unoccupied public restroom either. airborne respiratory viruses can be transmitted well after an infected person has left the room. depending on the public opinion at the time, 90-100% of people i see at the grocery etc are unmasked. many are coughing, sneezing, glaring, etc. whether i smile and nod, or shake my head in disgust, it has no affect on their behavior. i, myself, have remained uninfected as far as i know, but i acknowledge up to 60% of cases can be asymptomatic. a driving reason why i refuse to lower my guard.

Masks don’t work.

Scientifically if you wore a mask, you’re not clinically sane

Me too, don't give a dame what others think.

@@Native722 it has been proven scientifically that the mast did absolutely nothing if you saw the size of a viral particle moving through a mask you would think that someone who wore one was clinically insane

Same... I can't get vaccinated for COVID or for the flu. I almost died from a flu shot about a decade ago. So I have to wear a mask, and luckily I've avoided the flu. I haven't had it in 4 years now. The way I ended up with COVID is because my ex-husband refused to wear a mask at work and brought it home and I got too. UGH. Also, the other plus side about wearing a mask, is that you can be slightly more incognito when out and about... an introverts dream come true!

Unfortunately true.

Masks don’t prevent anything 😂😂😂 🤡

Yeah! I'm allergic to so much and wearing masks was a godsend

Masks don’t do anything. You can still breathe right? So they aren’t stopping anything. Covid isn’t a problem as long as you’re healthy. Stop living in fear.

Fantastic statement. I'm stealing your shoe comparison 😊

I don't wear masks. ever. Wearing a helmet in your car will reduce your chance of death. Wear a helmet.

Okay, and? Masks doesn't stop anything. You were lied to. Played like a fool. Accept and move on.

Ahh, Yes when bad public policy/health meets the general public it is always the people who 'did NOT consistently wear a mask in a properly fitted manner", instead of the guidance itself.

Well Charles, aren't you glad you aren't required to wear one! Common sense would tell you a mask helps, just because a bunch of GOP liars and cheats, couldn't write a decent piece of legislation if their lives depended on it decided to make this into a political football, doesn't mean you have to be a fool and follow along. Use common sense, and remember to wash your hands at the minimum after being out and about. Cheers

Both me and my family contracted the covid virus and got sick, so. I have long since been better and we never wear a mask😅 We also didnt fall in the pit with everyone else for the JUICE😅 Re-breathing your own air isnt healthy by any means.

I think a lot of people forget that N95s were being tested and certified in the US way before Covid, so "Do masks work" should not be a question in 2023. Yeah, there's A LOT of basic Covid info. that has not been "messaged" and disseminated well, which is understandable because it's a new virus and "special interests" got involved in public health. What's incomprehensible to me is that most people don't seem care to learn the basic facts of how the virus spreads and how to prevent it from spreading (masks are only one tool). I like to think that most people are not selfish, they are simply tired of hearing about Covid, they have busy lives and they don't know where to turn for accurate information, so they cling to whatever helps them justify their behavior so they can feel normal.

quiet please, dont wake the Bear

It's not that simple, as the video highlighted. Consider seat belts. They are more or less effective depending on the design, the individual using it (their height, weight, body type, etc) the height of the shoulder strap, and so on. The important data is that using a seatbelt is safer than not, the same is true of masks.

@sgtjohnson49 My point is when you create a video titled "Face mask effectiveness: What we know now", and what we know now is nothing different than what we've known for years, I would like more information. Otherwise it's just another click bate video and title.

So would she.

The virus particles "bounce around" the fibers of the mask .. Only thing she doesn't tell you is by scale it's like trying to catch mosquitos through a chainlink fence! 😆

Distancing doesn’t work either. To be actually effective would require 30 feet of space, which no one would ever accept. So they made up “six feet” out of whole cloth, based on nothing. There was and is absolutely no science to support it.

Social distancing was born when scientists thought COVID was spread by droplets. Now it has become evident that masks and improving air quality work a lot better, considering how COVID spreads through aerosols.

They want something physical. When you wear a mask and everyone sees you, you can think, "See how smart I am?" It works coz people seeing them find entertainment value too so everyone gets something out of it.

Just mask about between bites. Mask down, bite, mask up, chew, swallow. Mask down, bite, mask up, chew, swallow. Mask down, bite, mask up, chew, swallow. Simply do that 150 times per meal, 500 times per day.

​@@tabbycat8511do we not remember that even fauci himself was once aware that each time you move the mask you defeat it's purpose?

Such an ignorant comment. Surgical masks were designed to prevent dribbling saliva into open wounds, not stop microscopic pathogens.

@@jaysonoweh2227 Lol, the comments to this video are absolutely incredible. I think these are the people you see walking around in the middle of summer with a mask on their face while walking or in their car alone.

...the masks that surgeons use are meant to keep them from accidentally sneezing and coughing on an open wound. In the outside world, you dont need to wear a mask because your body has something called an immune system, that constantly gets infected and makes antibodies custom to youre body.

it’s all about harm/risk reduction. nothing you mentioned is a good idea if your goal is to remain uninfected. what you brought up is the less than perfect regulatory environment. eating indoors, flying, and packed indoor venues are all great ways to catch covid, flu, colds, etc. i’ll bet you don’t trust your government in many ways, but you follow all the rules they make around masking and covid? make it make sense. it’s sad (but expected) they have contributed to misinforming the public. even though powerful politicians called the pandemic over (it’s not) and told us masks are unnecessary, why is nearly everyone still getting sick? - still healthy over here rocking my n95 and only getting takeout.

As long as they mask up between bites, no problem.

Well, then schools have to be properly ventilated. More air purifiers (or Corsi-Rosenthal boxes, they can be done cheaply) at lunch rooms and the amount of viruses spreading in the air will significantly reduced. It's about layers of protection.

@@Insill how are we still worried about covid 😂😂😂

@@Anonymous2.2 because about 1k Americans are dying each week from it.

She might have used a lot of words for you, but the short answer was "yes, using models that would simulate the size of covid particles."

You're smarter than this. Oftentimes the people wearing the mask are coming and/or going from a place where they feel that a mask is necessary. Or perhaps it's a short ride and they'd rather not have to readjust their fit. Not really much different than somebody wearing a swimsuit while driving their car.

Brainwashed people. They don’t know WHY they’re doing something, they just know that someone told them to “wear a mask”.

She says all masks "do something" because anything between you and Covid is "something" and definitely better than nothing, but anyone who tests masks will tell you that cloth masks and those "baggy blue" surgical masks are way less effective than respirators with "electrostatic layers" like N95s, KN95s, KF94s and FFP2s.

Lol, baaah. Bah. Baaaaah. Baaah.

SHHHHHHHHHHHHHHHHHH

Exactly, that's how stupid they view their audience .. Instead she uses this childlike imagery, when in reality by scale trying to block a virus with a fabric mask is like trying to keep mosquitos out using a chainlink fence 🤣

YOU ALREADY KNOW THE ANSWER

All masks are different, but I learned that many N95s, KF94s, KN95s, etc. can be used for over 40 hours in normal conditions. Yes, they can get germy, but sweat/snot/dust probably won't make you sick--it's the virus that you want to avoid, and those masks have a middle layer with static, so that viruses are trapped there, where they are less likely to rub off onto your hands. It's a good idea to keep them as clean and dry as possible, of course, and some people choose to leave their used masks untouched for about 3 days to allow time for any viruses to die off--when masks start to stink and look gross, yeah, you want to change them. And there are some budget-friendly masks out there for those who don't want to reuse.

N95s and the better ones, can stay good up to 40 hours as long as they don't get diry, soiled, wet, and u take care of them like u said. Certainly u can change them mroe often than that, too!

You do realize when you wear a mask that you are harboring bacteria on youre face

Well it’s New Jersey they already contracted every disease known to man.

the misinformation from politicians and public health and social pressure from their peers has been highly effective. there is also a theory that a covid infection can affect the part of your brain that handles risk assessment.

I know! Why risk bacterial pneumonia when you don't have to?

So does Exercise

Yep, they're all compartmentalized, studying their narrow little fields .. Clueless as to the compound effects of such an obviously stupid behavior such as blocking the amount of oxygen your body can consume.

Anecdotal. My entire family wore masks during covid and we all caught it multiple times.

Plenty of studies have been done that you can look up in journals. Most reach the same conclusion: masks work. The real question is, are you actually open minded and want to learn, or were you just asking for some ax-grinding polemics?

Not always true especially with masks

@@Fornax70 Lets see if I can get yet another warning from YT censor drones. I found the info at C 19 Early very useful.

Yeah, like some oxygen is better than none right?

at the cost of education and employment and future diagnosis.....seems fair. What have we done about it since?

You need to study the size of food particles and smell. And you were wearing a KN95? Why not an N95 or a P100? Do you even know the difference? Unlikely.

I see other people saying this but I don't understand--maybe you can explain the confusion. Do you mean the very first question? He asks if masks are "helpful" and she says they are "very helpful" and then explains how they work. Isn't that an answer to the question? I think he was quick to change his question from "does a mask prevent Covid" to "is it helpful" because he knows, like she says, that no one can say they are 100% effective (just as with other protections like seat belts and helmets and birth control), but she explains that even 80% effective masks reduce the amount of virus inhaled which means there is less of a chance you will be exposed to enough virus to make you sick. Yes, she's choosing her words carefully, but the words and examples she uses show me that she DOES think masks work to block and trap virus particles and that there is no doubt in her mind that they are very helpful. But yeah, maybe she's not the best spokesperson for masks?

One minute in: Were you able to show that masks work scientifically? The answer is "no" because she deflects on the answer. What they showed could help, hurt or have no impact on transmission. The Cochrane Review has the best data. Hand washing seems to work a little, masks probably not.@@plum33

Thanks for the response. Correct me if I'm wrong@@captkerosene: I thought the Cochrane mask study gave people masks and noted that many didn't use them--so the MASKS were not tested. If we're talking about the same study, I don't think there was ANY DATA about how many particles the masks attracted and blocked. I read that they later clarified: “Many commentators have claimed that a recently updated Cochrane review shows that ‘masks don’t work,’ which is an inaccurate and misleading interpretation,” Karla Soares-Weiser, the editor in chief of the Cochrane Library, said in a statement. “The review examined whether interventions to PROMOTE mask wearing help to slow the spread of respiratory viruses,” Soares-Weiser said, adding, “Given the limitations in the primary evidence, the review is NOT able to address the question of whether mask wearing itself reduces people’s risk of contracting or spreading respiratory viruses.” For examples of actual mask testing, you can research "NIOSH approved" for example. In the US, if a mask is NIOSH approved it means that it was scientifically tested and shown to be effective at blocking and capturing VERY SMALL PARTICLES like dust and aerosols we breathe (that can carry viruses). I've actually seen the testing being done--lots of tools and technology I don't understand, but I think it makes sense if you think of it like this--putting a barrier between you and harmful particles is one way to keep those particles away from you, and the less particles you are exposed to, the less likely you are to be harmed by those particles.

12 air changes per hour are best. You need the filter in the building room u are in, as well as on your face. Guess what, if the filter is not on your face and a covidy person is next to u, you're going to get the virus from them even if you have the best HEPAs and corsi Rosenthals in the room. Right uo next to you without a filter on your face? The HEPAs won't clean the air in time in how quickly the infected breath will infect u. Same with RSV, TB, which is spreading everywhere, and flu. Yes, tuberculosis is back in the States. Look it up.

Sorry you lost your parents, they are still very much alive and you will see them again. In the meantime, thinking 3 mask is a bit much if you are saying that's how you wear them.
