U.S. Rep. Billy Long @USRepLong
I’m glad a federal judge threw out the ridiculous #mask mandate for commercial air travel. We shouldn’t be mandating masks for air travel while every other part of our lives are mask optional. 2:40 PM · Apr 18, 2022
Close contacts with any unmasked exposure to persons with COVID-19 had significantly higher odds of receiving a positive SARS-CoV-2 test result compared with those who had only masked exposure. In addition, close contacts who had multiple exposures, whether masked or unmasked, had higher odds of a positive test result than did those with only a single exposure. The percentage of positive test results among close contacts in this study (30.7%) was similar to that observed in previous studies (approximately 31%) (2,3). Consistent with findings from studies in nonuniversity settings (4,5), the findings from this study reinforce that universal masking and having fewer encounters in close contact with persons with COVID-19 helps prevent further transmission in in-person university settings.
Wearing masks and having fewer encounters with persons with COVID-19 reduced the odds of transmission in a university setting. In addition, there was no evidence of secondary transmission from either of the two students with only masked exposure who received positive SARS-CoV-2 test results, and who, because of the modified protocol in place, were allowed to forego quarantine. Universities opening for in-person instruction could consider taking mask use into account when determining which unvaccinated close contacts require quarantine if enforced testing protocols are in place. CDC recommends that universal masking be adopted in indoor spaces for vaccinated and unvaccinated persons in areas with substantial or high transmission rates and that masks should be worn in indoor spaces in areas without substantial or high transmission rates if you are not fully vaccinated (9). In addition, CDC recommends COVID-19 vaccination for individuals aged ≥12 years.
SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe. CDC recommends community use of masks, specifically non-valved multi-layer cloth masks, to prevent transmission of SARS-CoV-2. Masks are primarily intended to reduce the emission of virus-laden droplets (“source control”), which is especially relevant for asymptomatic or presymptomatic infected wearers who feel well and may be unaware of their infectiousness to others, and who are estimated to account for more than 50% of transmissions.1,2 Masks also help reduce inhalation of these droplets by the wearer (“filtration for personal protection”). The community benefit of masking for SARS-CoV-2 control is due to the combination of these effects; individual prevention benefit increases with increasing numbers of people using masks consistently and correctly.
Source Control to Block Exhaled Virus
Multi-layer cloth masks block release of exhaled respiratory particles into the environment,3-6 along with the microorganisms these particles carry.7,8 Cloth masks not only effectively block most large droplets (i.e., 20-30 microns and larger)9 but they can also block the exhalation of fine droplets and particles (also often referred to as aerosols) smaller than 10 microns ;3,5 which increase in number with the volume of speech10-12 and specific types of phonation.13 Multi-layer cloth masks can both block up to 50-70% of these fine droplets and particles3,14 and limit the forward spread of those that are not captured.5,6,15,16 Upwards of 80% blockage has been achieved in human experiments that have measured blocking of all respiratory droplets,4 with cloth masks in some studies performing on par with surgical masks as barriers for source control.3,9,14
Filtration for Personal Protection
Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns. The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron .14,17-29 Some materials (e.g., polypropylene) may enhance filtering effectiveness by generating triboelectric charge (a form of static electricity) that enhances capture of charged particles18,30 while others (e.g., silk) may help repel moist droplets31 and reduce fabric wetting and thus maintain breathability and comfort.
Human Studies of Masking and SARS-CoV-2 Transmission
Data regarding the “real-world” effectiveness of community masking are limited to observational and epidemiological studies.
An investigation of a high-exposure event, in which 2 symptomatically ill hair stylists interacted for an average of 15 minutes with each of 139 clients during an 8-day period, found that none of the 67 clients who subsequently consented to an interview and testing developed infection. The stylists and all clients universally wore masks in the salon as required by local ordinance and company policy at the time.32
In a study of 124 Beijing households with > 1 laboratory-confirmed case of SARS-CoV-2 infection, mask use by the index patient and family contacts before the index patient developed symptoms reduced secondary transmission within the households by 79%.33
A retrospective case-control study from Thailand documented that, among more than 1,000 persons interviewed as part of contact tracing investigations, those who reported having always worn a mask during high-risk exposures experienced a greater than 70% reduced risk of acquiring infection compared with persons who did not wear masks under these circumstances.34
A study of an outbreak aboard the USS Theodore Roosevelt, an environment notable for congregate living quarters and close working environments, found that use of face coverings on-board was associated with a 70% reduced risk.35
Investigations involving infected passengers aboard flights longer than 10 hours strongly suggest that masking prevented in-flight transmissions, as demonstrated by the absence of infection developing in other passengers and crew in the 14 days following exposure.36,37
Seven studies have confirmed the benefit of universal masking in community level analyses: in a unified hospital system,38 a German city,39 a U.S. state,40 a panel of 15 U.S. states and Washington, D.C.,41,42 as well as both Canada43 and the U.S.44 nationally. Each analysis demonstrated that, following directives from organizational and political leadership for universal masking, new infections fell significantly. Two of these studies42,44 and an additional analysis of data from 200 countries that included the U.S.45 also demonstrated reductions in mortality. An economic analysis using U.S. data found that, given these effects, increasing universal masking by 15% could prevent the need for lockdowns and reduce associated losses of up to $1 trillion or about 5% of gross domestic product.42
Experimental and epidemiological data support community masking to reduce the spread of SARS-CoV-2. The prevention benefit of masking is derived from the combination of source control and personal protection for the mask wearer. The relationship between source control and personal protection is likely complementary and possibly synergistic14, so that individual benefit increases with increasing community mask use. Further research is needed to expand the evidence base for the protective effect of cloth masks and in particular to identify the combinations of materials that maximize both their blocking and filtering effectiveness, as well as fit, comfort, durability, and consumer appeal. Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation.
And, this from a member of the republican majority in the Missouri House:
Rep. Justin Hill @HillForMissouri
Replying to @Kip_Kendrick
Masks don’t work against COVID. 9:52 PM · Nov 14, 2020
Some of the responses:
@HillForMissouri what medical school did you graduate from?
@HillForMissouri another thing. From an ER nurse at Progress West today, where my mom in law tested + today. 6 dead on her shift last 24 hrs. 2 couples came in husbands passed. It’s going to be a bad winter. Stay in & wear a mask when out. Funeral homes cant keep up. Ur a liar
Can you walk outside in the cold & see your breath? Do you know why? Because it shows the aerosol droplets when you exhale.. this is an amazing visual of how the virus can spread.. guess what happens when you put a mask on?? It’s the craziest.. thing you don’t see your breath
I wonder how someone can be this dense, but then I see you attended Liberty “University.” The stranglehold conservatives have on Missouri will doom us all.
Look, sir. Your constituents are DYING because of this stubbornness. Masks are not a 100% miracle armor but YES there is a ton of evidence that they help prevent transmission. A LOT. It’s a cheap, painless way to HELP. Seat belts don’t work either if you don’t buckle up.
You think Rep Hill cares if people die? Come on…the man is staunchly pro-life because it’s ok to regulate a woman’s body but it’s a crime to force her to wear a mask to keep from killing actual people.
Really? Then why did MO Governor @GovParsonMO approve this new set of guidelines for MO schools which emphasize mask wearing? You could go spend a day in an ICU full of COVID patients, where you don’t wear a mask or need one, to prove your claim. Prove all of them wrong.
The ignorance Justin Hill is demonstrating with this tweet is dangerous and an embarrassment for his constituents. He is not fit for office.
You can scroll his Twitter for 2 seconds and find that out. Koolaid drinker if I’ve ever seen one.
What a jackass statement.
This is why your district has been called out by the physicians on the task force in recent weeks for increases in both case numbers and hospitalizations.
I could share scientific journals, including from the US Navy, to prove you wrong, but you wouldn’t care. Quite a dangerous game you’re playing with our lives.
Here’s a simple explanation
a mask reduces the distance a bunch of your spew goes
I make contact with less or none of your spew & I don’t end up getting your crud
Also, a mask helps limit the amount of crud I suck in
All documented by scientists which you are not one.
Based on this tweet alone, I can say you are no public servant.
The next time you go seek medical care please ask your doctor not to wear a mask and hope it’s not one of the many that still have to work while they are covid positive.
And this is exactly the reason why we’re not able to get the virus under control here.
He’s doing this for attention. Most of his tweets are “look at me, I’m so shocking”. We need leaders in this state, instead we have preformitive attention seekers.
Kinda like a life vest doesn’t keep a boat afloat or a parachute doesn’t prevent airplanes from falling out of the sky?
What doesn’t work against COVID is the GOP.
You keep going out without one. The virus will beg to differ.
Actually, masks do help. Prideful ignorance, on the other hand, does indeed not work against COVID.
Science is impenetrable to the feeble-minded
That’s a lie that will get people killed.
Good to see you grew up, but you didn’t get over chugging lead paint.
That’s a lie that can cause death and the overwhelm of our health system. Who hurt you? Seek therapy.
This is ignorant and puts your constituents at risk. Masks work, so quit politicizing the issue.
Stupidity doesn’t work against the virus.
That Liberty education failed you…may want to ask for a refund.
Masks work. The doctors and scientists say they work. Crackpots don’t believe it.
And in your case, science doesn’t work against ignorance.
The ignorance just keeps on giving … just incredible
Bless your heart little man. Good to know you are so humble about your medical and scientific credentials #MOLeg
Got that good Liberty education, i see.
This is a reckless lie, Mr. Hill. Your constituents & all Missourians deserve better.
Repeating a lie does not make it true.
The Show-me State.
Because reading is hard.
Oh you dangerous idiot.
Dedicated public servant? That’s a joke.
Wait just a sec everybody, I’m sure an intellectual like Justin Hill just wants to have a good faith debate about the research he’s conducted which led him to contradict the prevailing consensus among public health/infectious disease experts. Lol jk, he’s weapons-grade stupid
You are not a scientist or medical professional. You are barely sentient.
There are no words for folks like you. To be raised by parents who hate and to pass that hate onto your children is truly remarkable. And that basically says everything about you. Satan will welcome you with open arms.
Stop with the Trumpist tropes. We all know about that article from last winter, and that there have been numerous studies of mask and covid19 that clearly demonstrate that masks most definitely work against this virus.
Keep up or go home.
You’re not very bright. That’s the tweet.
Masks do help to slow and prevent the spread of COVID
Masks don’t work against stupid.
Not only stupid but dangerous.
No wonder Missouri’s fucked.
Are you able to present empirical data to support that statement? If not, you are being reckless and irresponsible. Missouri deserves better.
Yes they do asshole
You don’t read much do you.
Fuckin clown show. Liberty education baby!
Found the liberty grad easily.
Goddamn do they feed you lead paint chips there or what?
You are proof nothing works against stupidity.
What? Are you stupid?!!!
Your stupidity is dangerous. That’s incredible really. To be so stupid that you’re a danger to the community. Pathetic
Justin…you’re easily be dumber than a bag of hammers. I swear the next time you park your stupid jeep in front of my house im going to get it towed. You are a sycophant and complete idiot endangering lives of your constituents.
There’s another story in there, don’t you think?
Damn you are dumb
You are as dumb as a rock. Is the earth flat in your world, too
My physician wife would strongly disagree with you. You absolute fucking MORON!! Come to the covid unit of the ICU without a mask. DM me for my number and I’ll hook you up. Seriously.
What are you, 12? Oppositional defiance? Grow up. Wear a damn mask.
You are an idiot. I could have sarcasm about it, but you are just an idiot, plain and simple.
You really must be some kind of stupid! Why don’t you volunteer in a COVID unit for 24 hrs and prove it!!
Former Vice President Joe Biden (D) [2020 file photo].
FOR IMMEDIATE RELEASE
October 2, 2020
Statement by Dr. Kevin O’Connor
Vice President Joe Biden and Dr. Jill Biden underwent PCR testing for COVID-19 today and COVID-19 was not detected. I am reporting this out in my capacity as both Vice President Biden and Dr. Biden’s primary care physician.
“Hey, where is your collection of old press credentials?”
“On the book shelf in the extra room. Why?”
“Don’t they have elastic cords on them?”
Even the most dedicated prepper doesn’t have everything they really need stored away for the next apocalypse. I mean, who could expect a quilter with a vast stash of cotton fabrics, including Batiks, to keep a supply of elastic cord.
There we are.
Every individual who has ever been issued a press credential to cover a major event (political or otherwise) saves those credentials. Some are fancy, with slick graphics, industrial lamination, and high end lanyards. Some are a scrawled piece of paper hastily thrown into a sleeve. Others still, are somewhere in between. Some of those old credentials were in sleeves with elastic cords to help hold them around the neck.
The credentials get saved. They may be thrown in a pile on a shelf somewhere, or matted and framed (depending on the perceived historical value) and displayed for all visitors to see.
Over the thirteen years of covering political events for this blog I’ve accumulated quite a collection of issued press credentials. I even have a few from rock/popular music concerts.
The surgical masks sewn by our resident quilter fit and work beautifully and happen to look great, too. Cotton Batik is used because it has a tight weave. There are multiple layers, a sleeve for wire or a pipe cleaner for the nose bridge, a sewn in pocket to insert paper towel or additional filtering material, and elastic cords on each side to fit over the ears and hold the mask in place.
But no one anticipates an urgent need for elastic cord for home sewn surgical masks, right?
In a time of plague, when one has a critical need for raw material which exists as part of another whole product, you cannibalize it.
And so, we did.
Press credentials as a source of raw material.
The finished products.
They wear well.
Self portrait .
Ironic on a certain level, don’t you think?
Stay Home. Wash your hands. Don’t touch your face.
